  1. Howdy y'all, I built an audio PC (see specs here) and am using HDPLEX's 200W linear power supply. This is plugged into a Furman PST-8D power conditioner. Question is this: would it be particularly unwise to place an Alexa "Smart Plug" in the middle, for some fun n funky home automation commands with Alexa? Proposed setup is as such: LPS > Smart Plug > PST-8D > (wall outlet) I've invested in this LPS and power conditioner—and all the other components in the PC including a JCAT USB card FEMTO—to optimize for audio quality. Would I be shooting myself in the foot by introducing something like this just for ease of use w/ voice commands? My gut says don't put a $10 piece of tech in between two several hundred dollar pieces of tech, which is why I'm posting this. But this may have no effect at all, which would be nice. Thanks in advance for your help 🙏🏻

  3. Given the other thread has spiraled out of control I'm starting my own. As OP here are my guidelines which I'll thank people to note and please try to respect: ON Topic: Discussion with the manufacturer and without asking him to reveal his secret sauce a chance to try and understand what he feels he's doing that provides high performance. Probing or critical questions are permitted as long as they are presented in a respectful manner. ON Topic: Any user experience. Past, present or future with these products. Ideally any comparisons to the usual LPSU suspects. OFF Topic: Assertions and arguments about building techniques that don't further our understanding of how these products may or do sound. OFF Topic: Sarcastic, rude and argumentative replies that do nothing to further the discovery element of this conversation. @Neverfinished0 - Hi Paul - I understand your frustration from the other thread and for what it's worth I feel you've had a terrible welcome to this site. That said there are some great and very knowledgeable members here and discussing details with manufacturers hopefully helps both the manufacturers and the community. I'll therefore respectfully ask you to please engage here in what is hopefully a more moderate thread. FWIW I have no knowledge or experience of your products beyond the other thread, but I'm intrigued. I am also potentially in the market so here's my situ: Audiolinux i7 NUC Server powered by 12V SOTM SPS-500 Audiolinus i7 NUC Endpoint powered by 12V Uptone LPS-1.2 Whilst both of these PSUs are pretty great, recent posts by other users have indicated that there may (or may not) be improvements to gain by providing: A. More voltage headroom. The i7 NUCs accept 12-24V and apparently higher is better. B. More amperage headroom. The otherwise truly excellent LPS-1.2 provides only 1.1amps and users need to disable a shitload of functions on the NUC to get it running on an LPS-1.2 I'm therefore considering: The Clones Audio Deluxe Powerstation. Dual rail, 15V, 1.5amps. Very good if very infrequent praise on some of the forums. The Paul Hynes SR4. Widely regarded as THE psu to beat. But alas Mr Hynes skills are offset slightly by the notoriety of his production lines reliability. So it's fair to say I'm intrigued but skeptical about your product lines. Skeptical partly due to lack of details and partly due to the low price point. But obviously I'd be delighted if PSUs at your price point do indeed perform so well. It doesn't help that is looks very much (based on posting and interaction style) that the other thread was posted by a user who has been banned twice here for a very aggressive and confrontational approach to those trying to help him. I truly hope I am wrong here. But some of the posts on the other thread exhibit a very, very similar style to that troubled user. So a couple genuine questions: 1. What would you recommend for my needs above? 2. Why would you say I should go for your products rather than say the Clones Audio Powerstation? Many Thanks, Alan
  4. Background If you are reading this review, then you probably already appreciate the key role that power plays in the sound quality of an audio system. I own or have owned a JS-2, two LPS-1, two LPS-1.2, and two sPS-500. I have also heard the benefit of a double regulated SR7 powering my OCX-10 master clock. With one exception, all of my DC cables are Audio Sensibility Signature Silver DC cables. The Audio Sensibility cables are made from cryogenically treated Neotech twisted pair 16 AWG solid core silver wire and terminated with cryogenically treated Oyaide connectors. The exception is a Linear Solution DC cable made from Neotech twisted pair 16 AWG solid core silver wire and terminated with Oyaide connectors. I have not had time to compare the Audio Sensibility and Linear Solution cables. Earlier this year, I decided to start migrating to double regulated power supplies for their superior performance. The obvious solution was to buy a second Paul Hynes SR7. However, from my perspective, the SR7 is no longer a practical alternative. I am now in the 14th month of waiting for my first order, and there is still no hint of a delivery date. One day, while looking at The Linear Solution website, I noticed that the LPS-912 power supply specifications were remarkably similar to those of the SR7. Was Adrian using the same transformer as Paul Hynes? Were these numbers even real? I knew some trusted sources had found the power supply that shipped with his OXCO switch to be lacking. Was Adrian capable of building a power supply equivalent to a double regulated SR7? I decided to find out. I had numerous exchanges with Adrian discussing my objectives and expectations while doing my best to assess his ability to build a power supply meeting his published specifications. Ultimately, I decided to take a chance and placed an order. Once Adrian began work, I found his commitment to be exceptional. He went through several design iterations until he was completely satisfied with the sound quality. One of his key goals was to create a circuit that worked equally well for both digital and analog devices. He delivered the power supplies only after he felt that they met his objectives and designated them as Reference 1. I took delivery 5 months after placing my order. The final build is as follows: Single rail 12v/6A with dual regulators Cryogenically treated transformer Class A circuit Parallel super diodes Quad rectifier diodes Neotech 16 AWG stranded silver internal wiring Mundorf capacitors Furutech FI-06 NCF IEC Ground post Black case Dimensions - L: 16” W: 12” H: 4” (ground post adds another 1.75” to overall length) As you can see from the photos, there is a large heat sink attached to the case. Consequently, it is always cool to the touch. Impressions Back in August, I had the opportunity to meet with @austinpop and @limniscate for a master clock comparison. One protocol was to determine the best power supply for my modified OCX-10. Listening to The Chain by Fleetwood Mac (96-24 version) on Eric’s Magnepan 3.7i speakers with dual Rythmik F12G subs, we compared the JS-2 and SR7. The SR7 was unanimously declared the clear winner. I am very familiar with The Chain, but with the SR7 powering the OCX-10, I heard elements of the music that I never knew existed. When I returned home, I was naturally disappointed to find my JS-2 powered OCX10 was unable to reproduce virtually all of those elements through my HE1000 v2 headphones. After the Reference 1 was burned in for a few days, one of the first songs I played was The Chain. Now, I can hear all of the missing elements just as I remember them on Eric’s system. Am I claiming that my headphones now sound like Eric’s speakers? Certainly not. I am simply saying that to the best of my memory, the previously missing musical elements are now all present just as I heard them in August. More generally, detail and dynamics are enhanced, with a better sense of space and image separation. The bass is tighter and more well-defined, extends deeper, and sounds more natural overall. The texture of instruments and voices is richer and more complex. For example, I have been enjoying and appreciating the vocalizations of Mark Knopfler and Robert Plant more so than in the past. It is as if the microphone feed goes directly to my headphones. Overall, the music has more energy and is more palpable. Limehouse Blues from Jazz at the Pawnshop (192-24 version) has always sounded dynamic and lifelike on my system, but now I seem to be present in the room, a mere 15 feet in front of the musicians, and surrounded by others in the audience. I also have experienced Jimmy Page’s guitar in a new way. There are now times when I can feel the speed and energy emanating from it. I have made a few tweaks that have yielded varying results. First, I connected the ground post to my Synergistic Research ground block via a Synergistic Research HD grounding cable. Grounding the Reference 1 in this way had a surprisingly noticeable and positive effect. The primary enhancement was to further extend the bass with even better definition. Second, I replaced the stock fuse with an Audio Magic ultimate beeswax SHD fuse. I could hear a small improvement, but I believe Adrian did a good job of selecting a fuse. I would recommend first applying those funds to a better power cable. Finally, I replaced my Audio Sensibility statement power cable with a Synergistic Research UEF blue high current 10 AWG power cable. This cable had a dramatic effect in terms of lowering the noise floor while improving the soundstage and dynamics. I highly recommend it. At some point, I will compare a Synergistic Research blue quantum fuse to the Audio Magic fuse. The blue quantum fuse produced a startling improvement in sound quality with my Auralic Vega DAC. I will also place some EMI paper on the inside of the case. Adrian has endorsed EMI paper as long as it is applied in moderation. In conclusion, the Reference 1 is an excellent product worthy of consideration by anyone who is interested in a bespoke, custom linear power supply as a means of extracting the best performance from their audio system. It is clearly head and shoulders above all of the other power supplies that I have owned. Until I am able to hear one side-by-side with an SR7, there is no way to conclusively state that they are truly equal. Hopefully, @austinpop, @limniscate, and I can find a time and place to perform such a comparison. For perspective, my chain at the time of these listening impressions can be described as follows: FMC > switch > sMS-200ultra > tX-USBultra > DAVE > HE1000 v2 The OCX10 re-clocks the sMS and tX, which in turn re-clock the switch and both FMCs. (The FMCs and switch were modified by SOtM.) The OCX10 and tX are each powered by a Reference 1, the sMS and switch are each powered by an LPS-1.2, and the downstream FMC is powered by a JS-2 rail. I utilize a Synergistic Research ground block and HD cables to ground various components and cables, as well as a Gutwire HD cable to ground the DAVE.
  5. So, while I patiently awaited release of the Sonore microRendu, thankful for my spot in the initial queue, I followed all the news and pondered what power supply option made the most sense for me. I could afford the lowest cost iFi but longed for the higher performance of other options available at a cost over my budget. This led me to a friend who has been building his own audio gear for many years; everything from Pass First Watt DIY single ended amps to video & music DVR/servers. He is squarely camped with one foot in the DIY world and one in the audiophile world regularly participating in local audio club events so he gets regular opportunities to listen to many very high performing systems. I've always been impressed with his ability to combine solid proven engineering concepts and an open-minded but skeptical approach to many of the audio "traps" that many enthusiasts fall into. After begging, pleading, much food & drink, etc. I talked him into taking on the D-I-H "Do It Himself" project of building me a suitable LPS to use with my microRendu. So for the benefit of anybody considering a similar approach & to motivate the builders here, you can see a description and some pics below. (No, he isn't looking to build/sell these to others!) Sorry, I am no engineer, so might not be able to answer some of your technical questions about the circuit. Sonically, I am thrilled with the results. A significant upgrade from the adjustable Hosa wallwart that I had been using. At a cost of $185 in parts, plus a number of days of toil & sweat, I think we have the sonic equivalent of a much more expensive LPS and about as good as possible sound quality within my budget. It also needs to be repeated that the Sonore microRendu is a remarkable achievement and I can't recommend it more highly! Thanks for reading.

  6. I'm building a 2-chassis music server/controller and have been reading about all the various external power supply vendors. I'm pretty confident that replacing the switch mode supply that I buy from Newegg with a purpose-built linear supply will make a big difference, especially in a highly resolving system like mine. There are a ton of companies that make lab-grade multi-output linear supplies that have very good specs. However, I've not found anyone in a forum who has re-purposed one to power a music PC. For example, this model (http://www.tequipment.net/InstekGPC1850D.html#tab-specifications) sells for $400 and appears to have superior specs compared to the audio PS vendors. Of course, in order to power an ATX mobo a custom wire loom is required but that isn't overly hard to make. Which brings me to my questions: Are there aspects of the purpose built music server power supplies that make them superior to the lab-centric benchtop products? If so, what are they and could I find a lab power supply that has those superior specs. Ultimately, I like getting good value for my money and there are an order of magnitude more lab PS vendors than audio PS vendors which means I can get cheaper gear and have a good selection of excellent used gear as well. I appreciate any thoughts, feedback and guidance you can provide.
  7. I just finished my DIY audiostreamer. The base is an AsRock motherboard with onboard processor (Q1900-ITX), wide PicoPSU, 3 linear power supplies (PSU) for the mobo, the ssd and the PPA USB V2 Card (Paul Pang). I made linear PSU’s based on the sigma 11 DY project by AMB laboratories (USA). Currently, I have installed Daphile. More info and photo's on: https://audiostreamerdiyproject.wordpress.com/
  8. Okay here is my question. I have a HDPlex 100W linear power supply and a SOtM sMS-200 on the way. I will power the sMS with the linear power. My DAC is powered by USB and also receives digital signal over the same cable from the sMs. I am wandering, because I am supplying the sMS-200 with clean linear power, will the DAC will benefit as well or if I need to get an adapter like the UpTone Audio USB Regen to split the power off from the usb out on the sMS-200 and add back in power from my HDPlex supply? So firstly would it be beneficial to power the DAC separately versus off of the sMS (powered from a 100W linear supply)? Secondly, if it is beneficial to power the DAC separately, instead of an expensive USB Regen and more high quality cables, could I not just order a high quality USB-Y cable and remove the ground and 5v connections from the first male end that goes into the sMS-200 and then just plug the other male end directly into my linear power supply so that data is received from one male tip in the sMS and power is received from the other male tip in the linear supply?
  9. I was wondering if I use an iUSB Purifier if I'd still need or want to get a Linear USB PSU for my Paul Pang USB Card? Does the iPurifier accomplish the same thing for less money and hassle? Also do all SATA (like SSD Drive ) require the same voltage and power requirements? Is it possible to find a Linear PSU that will supply power to both the USB card and SSD drive? WHat manufacturer?
  10. Hi, I am brand new to the forum but have been reading furiously in the last few days. Just joined. I am very curious as to what you guys think of my plans, as well as advice and constructive criticism. I have built pc's countless times, but this is my first audio specific build that will be designed for high quality digital out. Okay into the meat of things. Here is the main use: My dad has an extremely nice stereo room in his basement and a very refined ear. The room is very acoustically pleasing and I am unsure of his current equipment because he is always switching between his favorites, but for any of you skeptics out there, the last set of speakers he owed and sold were a set of ATC SCM 150 Active Speakers in a custom birds-eye maple finish that were purchased by a recording studio in Nashville. Look them up if you are unfamiliar, made me well up with tears the first time I heard them running with tubes. Anyways, I have a huge collection of 'lossless' audio we would like to play on his stereo and my father has been interested in joining a service like tidal to stream lossless but currently has no dedicated equipment to handle these tasks. I have bought parts to build something to take on the challenge and hopefully please his ears. Motherboard: I prefer MSI motherboards. Also I wanted something with a low power consumption. Small form factor was also a goal initially (before I found out the size of my CPU cooler). I went with a mini ITX MSI H110i Pro AC. Will not be taking advantage of the wireless guys, I know better. I already have a ethernet cable run direct from the source through the wall to where the finished product will sit. https://us.msi.com/Motherboard/H110I-PRO-AC.html#hero-overview CPU: Low TDW for less heat Intel I5-6400T. This is decently powerful but also only consumes 35 watts maximum. It is compatible with the choices I have for software in the end and networking reliability is supposedly better on Intel for pulling from a NAS than any AMD equip. https://ark.intel.com/products/88187/Intel-Core-i5-6400T-Processor-6M-Cache-up-to-2_80-GHz CPU Cooler: I forgot to mention that I would like a fanless design...well actually let's say no moving parts. I chose a huge Zalman FX70 cooler that should get the job done no problem. Completely passive and after some very enlightening talks with one of their engineers, I was assured that with my CPU this build would be very possible. ZALMAN - FX70 Memory: I had some newegg credit and found a really good deal on some highly rated 8gb stick so I just went with 16gb of Geil Evo Potenza. Also like that the memory has heat fins on the top to dissipate heat since I will not have fans. DDR4 EVO POTENZA DUAL CHANNEL Kit - Products - GeIL Memory Storage: I obviously want solid state for numerous reasons. I can use M2 with my motherboard but prefer 2.5" so I still have the ability to power it separately. I will only store the operating system on this most likely. I will stream predominantly and sometimes plug in with a separately powered external ssd drive. Since my collection won't be stored locally on this build, I did not need huge capacity and chose the Crucial MX300 525GB SSD which should be ample. Crucial MX300 525GB SATA 2.5" 7mm (with 9.5mm adapter) Internal SSD | CT525MX300SSD1 | Crucial.com Power Supply: For starters, my mini itx board does not take a direct 19.v input like most. It has standard ATX power. Additionally, I have a system that peaks at 86 Watts, so I don't need anything major. I considered linear first and got scared away by the cost being so high. Then I looked at picoPSU and found that some users experience noise introduction and scared away. I made a small mistake and bought a Seasonic 400w fanless PSU because of good reviews from fellow audiophiles, but then quickly became reluctant and cancelled the order and instead chose the HDPlex 100W Linear Power Supply coupled with the HDPlex 300W HiFi DC-ATX (NanoATX Series). The 400W version includes the ATX conversion but was just too expensive for me to justify. I additionally could have picked the HDPlex 160W DC-ATX but it did not include the audio specific capacitors that are used in the 300W Hifi unit. HDPLEX Fanless Linear Power Supply for PC Audio and CE device HDPLEX-300W-Hi-Fi-DC-ATX-Power-Supply (16V-24V Wide Range Voltage Input) DAC: We already own a Resonessence Concero HD which I am very pleased with. I will be using this for the heavy lifting. CONCERO HD - Resonessence Dacs - True Audio Clarity Case: Welp....you got me there. I have been unable to find something that I like. I have a friend who has a precision CNC machine though and he said we can design and build something with that to meet my needs exactly. I have put only a little though into it but I am thinking about bottom mounting the motherboard next to the LPS which will be internal. Have a roughly 14 inch long face, 10 inch deep sides, and a height of approx 8 inches. Just rough measurements. Cut the sides and base out of wood. Vent the sides nicely and use thin pieces. Have the back side cut for the ports and power. Stain the wood and put a power button on the front. Place half inch rubber nubs on the the corners on the open top. Have a piece of glass cut to size that sits on the rubber nubs. So it would be stained wood on 5 sides with venting and then a half inch top gap between the sides and the glass top to allow heat to rise out in all directions easily. Clear glass top to see components. Ideally have the top of the cpu cooler sitting a quarter inch or so away from the glass so its top is slightly visible from the sides of the box. It is a precision cnc so I can have it draw a logo into the front as well. My Questions: Is it good practice to simply run USB out to the DAC for power as well as digital audio or do I need to seriously consider getting a card that has S/PDIF out and powering the DAC from the wall or the HDPlex linear supply? How should I run the power? Please help here! Is Tidal streaming truly lossless? What software should I use? I need it to be controllable by phone or tablet. Once this pc is setup it will not have visible video out. The controlling of audio playback needs to be done on the phone or tablet. Also the interface needs to be pretty simple. I have seriously been considering roon labs because it seamlessly incorporates Tidal into the library and my dad will predominantly stream from Tidal if it is truly lossless. Should I be worried about clocking? Am I capable of Asynchronous USB? For the money I have spent (before DAC), is there a roon-ready recommended player that I can afford that will produce better quality? (around $1000) In the past I have only used usb out to a headphone DAC with an ASIO driver using foobar for playback. School me up people. Please help me along the way. I know some of you have been where I am at and now have a ton of experience to share.
  11. Hey there. I have a PS-1 in mint condition for sale with three modules (and cables) included. It's modular design allows up to four devices to be powered at once, and they can even be different voltages. The PS-1 has four power zones in back. Each power zone holds a power module. Each power module can be set to one of four voltages (5v, 9v, 12v, 15v) and can power one device. I bought brand new from Wyred 4 Sound and have used it to power up to three different devices myself, including Chord 2Qute, SOtM sMS-200, and SOtM tX-USBultra. It's bloody brilliant, but I recently sold my sMS-200 and 2Qute, so I really only need a power supply for the tX-USBultra. Retail on the PS-1 with three modules is $700, plus shipping. I am looking to get SOLD $500, asking buyer pay PP fees and shipping. Pics up shortly. Thanks for looking!
  12. SBOOSTER "BEST OF TWO WORLDS" AUDIOPHILE POWER SUPPLY (BOTW P&P ECO) The Sbooster “Best of Two Worlds Power & Precision ECO” audio upgrade (BOTW P&P ECO) is the successor of SBooster's “Best of Two Worlds Solutions” audio upgrade (BOTWS). This new upgrade product combines power, precision and efficiency in an unique innovative manner that purifies the incoming current immediately upon entering the device. A dual stage mains filter and an earth line choke clean the current from high frequency pollution before the current reaches the transformer. The transformer is a custom-made audio grade transformer with electrostatic shielding. The electronic design allows for up to 50% more output out of the used electronics and consumes even up to 35% less energy than a conventional design. Even though it provides a significant boost in available power, the BOTW P&P ECO audiophile power supply is so efficient that it consumers only a fraction more of electricity than what a standard power does. ULTRA ACCESSORY The Sbooster Ultra Filter Accessory can be used as an addition to the many filtering and optimization techniques of the BOTW P&P ECO audiophile PSU and can only be used with the SBooster split-current module of the BOTW P&P ECO. The Ultra is based on active filter technique, which reduces the ripple & noise of the BOTW P&P ECO even further: to a negligible low level. The Ultra is designed for audio equipment that is highly sensitive to residual noise, such as digital to analog converters, music streamers, USB to SPDIF converters, headphone-, pre- and phono amplifiers. In addition to the active filter function, the Sbooster Ultra also re-stabilizes the output voltage to the correct voltage and because of the short cable length of the Sbooster Ultra, the highly purified powered is passed to your audio device with no performance loss . Main benefits of BOTW and Ultra Filter Accessory: Up to 50% more power to your amplification components Lower noise floor and blacker backgrounds to your digital components Improved musical rhythm and timing These products qualify for Free Shipping and 5% back in points when you register for Club Ciamara Membership Rewards Program 1.844.CIAMARA (1.844.242.6272) High End Audio Store NYC - Experience Ciamara
  13. I'm interested in upgrading the noisy SMPS on my SBT. I've been looking at a couple namely the following. Astron Sl-11R: Astron Linear Power Supply 13.8 Volts 11A SL-11R (http://www.astroncorp.com/linear.shtml) and really good pics at: http://store.stsi.com/sl-11r.html Welborne Labs Squeezebox Linear Power Supply: http://www.welbornelabs.com/squeeze.htm The Welborne is ready made and cost's only $212 + shipping. The Astron looks to be a good value at under $100, however it needs some mods to make it compatible with the SBT. First it needs a proper power plug. Second, the power supply needs modification to bring it down to 5amp, and 12volts. Currently it is a 7a, 11a power supply (although it measures 13.8 volts). Has anyone any experience with these or others?
  14. I have recently changed my system topology and no longer need my UltraCap LPS-1. It is in excellent condition.

Hey folks, I'm planning to buy this LPS : Linear Triple DC Power Supply RXN-305D-II (2x 0-30V 0-5A, 1x5V) It has 3 output channels: -one constant 5V 3A -two 0-30V 5A (will be using 2 x 12V) Im planning to feed my future control pc and audio pc (picopsu 150W and 160W) and a ssd with 5V. As I really don't know anything about these connection types, I will need an expert opinion if everything will work and I will not blow anything. Thank you very much!
  16. I just finished this PSU for my CAT. Some figures measured from the AC receptacle (with +/-5% error I suppose) -when PC is off (in standby mode): 20W -when PC just starts (where the peak comes): 90W -when PC running smooth after boot up: 70W The circuit design refers to this: Linear ATX power supply - diyAudio with some change of regulators (I use LT1083 for every voltages, and dual 12V rails), basically they are the same thing just more capacity.
  17. Hi all, I would like to finally (I've been busy with this sometime) give my audio pc a decent linear psu. I've done a lot of reading and a few things are not clear for me. That is why I started this topic, to gather a good vision on what's best and what is affordable. The first thing I need to know is what I need to power and what power requirements these components have. (I also put a few components in from the control pc, because I would to power this one also in the future, the ones I would like to power first are in bold and italic).

Is this true? Or am I overlooking something? From what I have red on the forum and also my own experience with feedback from Paul Pang, the PPA USB card could use 5V and 1A but it sounds better when it is 5V and 3A. I use a ASRock Intel H77 H77M ITX and a Asrock B75 Mini ITX motherboard. Both are equiped with Crucial ballistic 4GB sticks (2sticks, 8GB a system). Both systems are powered with PICOPSU-150 – XT + seasonic 12 Volt 80 watt power supply. So they feed these components I need 4 lines (one for the CPU, one for the CF card, one for the USB card and one for the Pico psu). Are there any benefits to power the CF card and USB card separate with a battery for example? The Balkoon route with two Balkoon's powering the CF and USB card will be to expensive for me (it is about 1000 euro's with shipping for me). I have red a lot about the Anker E4 battery, is this better then a good linear psu? There is a Quad-Rail ATX PSU on ItemAudio, but this one only has one 12V which means I can not feed both the CPU and Pico seperately. (Quad-Rail ATX PSU - Item Audio) PPAstudio has a few options but with shipping it is expensive and I use for both pc's a Streacom FC8 case. Which means the regulator bords will not fit into the case. He does sell a 120W psu, wich might would be strong enough to power both CPU and Pico (dual rail12V, 6A each). http://ppaproduct.blogspot.tw/…..r-psu.html This option would fit in my budget when I would use two cheaper batteries for powering the CF card and USB card. But then again, would be two of those supplies better then one with batteries for the other two components? Is it realistic to think one audio pc can be properly fed with a linear psu (or multiple) for about 1000 euro's? Thank you for reading and if you have some valid info please reply
  18. I recently installed a couple points of fiber optic isolation on my network. One between the switch and my Mac Mini server (TP-Link MC200CM with 15 foot duplex cable) with the other between the switch and PS Audio Directstream DAC (TP-Link MC100CM with 5 ft cable- the MC200CM wouldn't work with my DAC!). As of right now I am powering my PS Audio LANRover and the receiving module for the DAC with my UpTone Ultracaps LPS-1 with splitter. So I'm wondering if there's any point in getting another LPS-1 for the sending units as well. I can theoretically see the benefit of doing do, but does it really make a difference? And is the receiving unit to the DAC the one to power with the LPS if you can only choose one fiber module? Any input is greatly appreciated!
