  1. View Classified UpTone Audio UltraCap LPS-1.2 + UpTone Power Supply + Output Display Gently used, excellent condition. Board version 1.4. [Note - I have two of these for sale, listed separately] From UltraCap LPS-1.2 – UpTone Audio: The world's first bank-switching, microprocessor-controller, ultracapacitor-based, ultra-low-noise external linear power supply has arrived! In development for more than a year, and with 262 parts on the double-sided, 4-layer circuit board, this tour de force of engineering challenges traditional notions about what is important in power supply design. Use of the UltraCap™ LPS-1.2 in a quality music reproduction system will yield surprisingly audible improvements, and we invite comparisons to any other low voltage linear power supply. The LPS-1.2 is a single output, 1.1-amp linear power supply intended for powering a wide range of audio and computer devices. Examples include: UpTone's own ISO REGEN, the Sonore microRendu and ultraRendu, SOtM streamers, small DACs and headphone amps, USB>S/PDIF converters, specialty computer USB cards, SSDs, fibre media converters, PS Audio LANRover, SqueezeBox Touch, etc. A switch on the back of the LPS-1.2 allows for setting of the output voltage to 5V, 7V, 9V, or 12 volts. The input and output jacks of the LPS-1 are standard 5.5mm x 2.1mm size DC barrel connectors. "I recently replaced one of my LPS-1 with LPS-1.2, and like the result quite a bit. While trying this new supply, I also put it in other positions in my system to compare, the result in raising the SQ seems consistent, so a week later, I ordered another two to replace two other LPS-1's I have. With one week of burn-in, I am pleasantly surprised how much more the improvement is. I knew the improvement would be quite tangible, but for sure was not prepared to be this much. Overall detail retrieval, smoothness, dimensional layering, space between instruments are all took a nice step up. Kudos to UpTone for this fine product!" —Kevin S., Fremont, California Note, The UltraCap LPS-1.2 has a small, 3-pin (standard 0.1” header pin spacing) port for measuring output voltage and device current draw. Typically measuring the current draw of a device requires putting an ammeter in series with the power cable (DC or AC) feeding it. But this clever port provides a measurement of current with a voltage: 1 Volt equals 1 Amp. So if you measure 0.2V (across the pins labeled ‘G’—for ground—and ‘I’—for current), that means the device you have attached to the output is drawing 0.2A or 200mA. The pin labeled ‘V’ always outputs the voltage that the LPS-1.2 is set to. Small displays are available cheaply to use this. I am including such a display which can be inserted into the GVI header (black wire goes to the 'G' pin) for real-time monitoring of output amperage! Note, UpTone is NOT accepting orders for these due to supply shortages, so your only chance to get one is the secondary market. Price includes shipping to CONUS only and PayPal fees.

Examples include: UpTone's own ISO REGEN, the Sonore microRendu and ultraRendu, SOtM streamers, small DACs and headphone amps, USB>S/PDIF converters, specialty computer USB cards, SSDs, fibre media converters, PS Audio LANRover, SqueezeBox Touch, etc. A switch on the back of the LPS-1.2 allows for setting of the output voltage to 5V, 7V, 9V, or 12 volts. The input and output jacks of the LPS-1 are standard 5.5mm x 2.1mm size DC barrel connectors. "I recently replaced one of my LPS-1 with LPS-1.2, and like the result quite a bit. While trying this new supply, I also put it in other positions in my system to compare, the result in raising the SQ seems consistent, so a week later, I ordered another two to replace two other LPS-1's I have. With one week of burn-in, I am pleasantly surprised how much more the improvement is. I knew the improvement would be quite tangible, but for sure was not prepared to be this much. Overall detail retrieval, smoothness, dimensional layering, space between instruments are all took a nice step up. Kudos to UpTone for this fine product!" —Kevin S., Fremont, California Note, The UltraCap LPS-1.2 has a small, 3-pin (standard 0.1” header pin spacing) port for measuring output voltage and device current draw. Typically measuring the current draw of a device requires putting an ammeter in series with the power cable (DC or AC) feeding it. But this clever port provides a measurement of current with a voltage: 1 Volt equals 1 Amp. So if you measure 0.2V (across the pins labeled ‘G’—for ground—and ‘I’—for current), that means the device you have attached to the output is drawing 0.2A or 200mA. The pin labeled ‘V’ always outputs the voltage that the LPS-1.2 is set to. Small displays are available cheaply to use this. I am including such a display which can be inserted into the GVI header (black wire goes to the 'G' pin) for real-time monitoring of output amperage! Note, UpTone is NOT accepting orders for these due to supply shortages, so your only chance to get one is the secondary market. Price includes shipping to CONUS only and PayPal fees.

  5. I have a SOtM- SNH10g switch, powered by the SPS-1000 power supply. Through Finisair SFPs it cascades into an EtherRegen powered by Farad power supply. The EtherRegen is also connected to a 10MHz Queen clock from AfterDark. The clock is fed by an AfterDark power supply. From the EtherRegen B side I connect an Innuos streamer and then it goes to a DAC. This is my question: Can I replace the AfterDark clock with another output from the SPS-1000 power supply, which is supposed to be better? I know in theory yes, but i wonder if feeding both stages with a single power supply would defeat the purpose of the cascade. Leakage currents maybe? I would really appreciate your inputs.

  8. I have a question for all of you wizards out there. (I didn't see a more appropriate area of the forum for A/C power discussion, so I am posting here.) I have suspicion that voltage drops / brownouts have caused some havoc on our home-automation control system (Crestron). I am currently researching power conditioners, regenerators, UPS, etc. Even within the confusing, subjective world of audio, this area seems like a particularly dark black hole. Question: Does anyone know of a device or tool which can be used to monitor a home’s electrical system? I am envisioning a connected device that can be plugged into an A/C outlet and it measures/monitors/logs spikes, surges, dips, noise on the home's wiring. Real time monitoring would be OK, but the real value would be to see the results over a period of time (a week or so). Any help appreciated. Thanks, Bart
  9. Hello, I am new to the forum and new to raspi but do know just a little linux, and have just bought the i2s Isolator and Boss (in transit, not yet received). Can someone please shed some light about the LifePo4 18650 batteries required for the i2s Isolator. I have read elsewhere; there are different types of these batteries i.e. "Use of a unprotected rechargeable LiFePO4 where a protected cell is expected is very dangerous". My questions are: 1. Does the LifePo4 batteries get charged from the raspi, or would you need to manually recharge them, or are these batteries non rechargeable 2. do I need to be concerned about "protected" and "unprotected" LifePo4 batteries for the i2c Isolator 2. Allo recommends the battery option for the i2s Isolator but would a "Dual LLC PSU" be "as good" or "not so good" 3. what would be the best overall power arrangements for the raspi + Isolator + BOSS i.e would I power the raspi via usb and power the BOSS via the i2c Isolator batteries All help will be very much appreciated Thank you in advance
  10. I've run into a new problem and didn't know if anyone had any similar experiences/solutions. Thanks in advance. I am currently using a microRendu in an area of my house that does not have (and cannot easily get) wired ethernet. I tried using it plugged into an eero base, but had some drop outs. I have been using TP-LINK AV2000 Powerline Adapter with good results. I changed up my system and with my new Wells Audio Milo I am picking up noise from the power line adapter. If I move the adapter to a different outlet than my amp is plugged in, it improves. I still have audible interference (sounds like data transmission to me) but it is better than when both are plugged into the same outlet. I have had some improvement adding a better/shielded power cable (Cardas Clear M). It's better but it is still there. If I turn off the DAC (Schiit Gugnir Multibit), the sound is still there in the background--so I think it is from the amp itself. Any suggestions? I'm looking into hardwiring the ethernet, but this will be expensive and require drywall work. I've considered the Auralic Aries, but like my microRendu. Thanks for any suggestions. Mark

  12. I have an Allo Boss DAC 1.2 installed on a Raspberry Pi 3B+ running Moode 4.3. 1) If I have J25 installed and power the DAC and Pi from a single 5V power supply, music plays, all works. On the Boss DAC, both the power LED and LED1 light up (green). 2) If I remove J25 and use two 5V DC power supplies, one to the Boss DAC USB-C and the other to the RPi3B+ USB Micro-B, it seems the DAC does not work. Only the power LED lights up, but LED1 remains dark no matter what. When I try to play a music file, I get this error: MPD errorFailed to open "ALSA default" [alsa]Failed to open ALSA device "hw0,0" Nosuch file or directory It appears the DAC is not working with J25 removed.

  13. My current DAC only way of receiving power is over USB. I have the ability to power it over the USB and send it digital signal through S/PDIF, but I just ordered a SOtM sMS-200 and I would like to use it in my setup. I am wandering if the sMS-200 audio usb port sends digital audio signal as well as 5v power. I know some high end audio units strip the 5v power line out of a USB to remove a possible source of noise, so that is what made me curious as to whether the sMS-200 will power my DAC as well as send it digital signal. I have asked the question twice to SOtM, but there appears to be a translation issue and they think I am just confirming that I can send digital signal to my DAC via USB. I know that if it does not output power over USB then I will be forced to buy something like the UpTone Audio USB Regen to allow me to add power to the line cleanly from my linear supply. If anyone has insight on this issue please share your knowledge. If I need a device to add power to the USB line then I would like to order it now so I am not sitting staring at the sMS-200 waiting to hear it. Thanks guys. Mike
  14. I have 2 studio monitors and a streamer, all with smps, and very power consumption, like under 30 watt each. Smps devices pollute the power system so one needs power socket / Filter with individual filtering for each socket. I am interested in surge and spike protection to prevent the smps from running hot (we have a lot of Voltage variation here). The filtering / protection must be very sensible cause smps devices need instant current and usually sound less dynamic with filters. Any advice? Would like to stay below 700 stones... (European devices preferred, I have schuko plugs)
  15. WHAT IS THE TRUE EXPERIMENTAL TWEAK THREAD ALL ABOUT? I have always wanted a thread where any subject is possible. No experiment is too crazy to add here. No idea is too bold to reveal. Take it away! Enlight your thoughts and share your ideas how to improve SQ and how not to. Anyone can encurage and educate you but no one should let you down, deminage you or simply move you to another thread. Everyone is welcome as long as they accepts a different way of thinking! TOPIC DIGEST With a little help of @austinpop I have realised that this thread is all over the place. Even if this is one of the fundamental ideas behind this thread, it could be a good idea to sum-up the things that have proven to be beneficial to SQ in this thread. I will keep it plain & simple. Remember that these are essentially my own findings in my own setup with Tidal FLAC and Tidal MQA as source. As always YMMV! LAN 1. Cat 6a U/UTP 500Mhz ethernet cables sounds better than Cat5, Cat5E, Cat6 & Cat7+ in my setup. Ghent Audio Cat 6a ET02 with JSSG shielding and Metz plugs rules them all. 2. Network switch improve SQ with input on port 1 and output on the last port. Possible explanation is QoS and also that the ports are in different magnetic boxes inside the switch. 3. Using a AQVOX switch with better clock improves SQ compared to a D-Link DSG-105 network switch. 4. A wireless adapter/wireless bridge/router in client mode into a network switch sounds better than battery powered FMCs and hardwired LAN. 5. Router vastly improves SQ with a floating LPS and even more if the floating PSU is connected to a DC blocker trap filter. IME a router upgrade could be beneficial to SQ. 6. Galvanic isolation/DC blocker in the signal path pre the router improves SQ. 7. Wireless adapter vastly improves connected to a floating IT. 8. RJ45 socket enhancers seems to be more efficient on port 4 & 5. Don't ask me why! GND 1. Grounding a metal chassi network switch to a tourmaline grounding box greatly improves SQ. 2. Different tourmaline grounding boxes improves the sound signature in different ways. 3. Grounding the DC negative terminal of the floating SMPS works great. In my setup it sounds best connected to a grounding box instead of to the power strip safety ground receptacle. Just be aware of possible leakage loops between various network devices. A big thanks @JohnSwenson for this tip. USB 1. Covering the outer USB barrels with electrical tape improves SQ slightly with unshielded USB cables. Capasitive coupling between metal barrel and pins? 2. Uptone Audio´s USPCB improves SQ. 3. ATL Hi-Fi´s 8 conductor USB cable with dual unconnected shields (5v+GND & Data- & Data+) with JSSG loop improved SQ compared to other longer (<50cm) USB cables that I´ve tried. DC 1. Network switch sounds best with dual floating PSUs or battery power (but very important to disconnect the battery charger while listening to music). Dual floating PSU is slightly better than battery power, but battery power is slightly better than single floating PSU. 2. Powering several devices with a single floating SMPS sounds better than powering the very same devices with several battery supplies. Also, powering several devices with a single battery supply sounds better than using multiple identical battery supplies. Self-inflicted noise? 3. Canare 4S6 starquad does improve SQ where ever applied. Canare 4S6 with JSSG seems to be even more effective. Thanks [email protected]! 4. Grounding the DC negative output of a floating SMPS improves SQ. Grounding the chassi/case decrease SQ. Be aware of shared ground paths since this could potensially decrease SQ. 5. Dual LT3045 ultra-low noise voltage regulators in series with 1v drop-down close to the powered device improves SQ quite dramaticly. 6. Kemet aluminium Polymer caps A750 series (25v 560uF) vastly improves LT3045 when added at the DC output. On single LT3045 the Kemet improves on both in- and output. 7. Panasonic FC series type A aluminium electrolytic caps improves on the PSU output terminals. AC 1. A DC blocker trap filter pre a safety isolation transformer improves SQ even though it is dead silent (no hum). DC blockers trap filter pre a floating PSU into a router vastly improves SQ. DC stress reliever? 2. SQ improves when battery chargers is connected to a separate powerstrip connected directly to the AC wall outlet, bypassing the isolation transformer completely. 3. A safety isolation transformer with floating secondary improves SQ more than a Ultra Isolation transformer. A balanced isolation transformer with floating center-tap rules them all! 4. Daisy chained floating grounds (dual floating grounds) sounds better than a single floating ground. In my setup floating SMPS's improve SQ connected to a floating IT, even surpassing battery supplies. Thanks for the suggestion @lmitche! 5. AC mains starquad power cables greatly improves SQ. 6. AC mains voltage regulators improves SQ on the signal chain. Even cheaper versions are effective. Not as effective on high power devices such as active speakers and amp due to a still unknown reason.
  16. Hi all Just wanted to ask if there are any PS Audio DirectStream DAC owners out there that have paired it directly with a Benchmark AHB2 power amp? I'm thinking of trying out this combination and I'm trying to arrange a demo for January but in the mean time I'm interested in hearing anyone else's thoughts, that's tried this combination specifically. Thanks in advance :-)
  17. I am considering a "PS-Audio Direct Stream Power Plant 15", any advice or information is welcome: Context: https://audiophilestyle.com/profile/30314-gato/?tab=field_core_pfield_3

Shunyata Venom MPC-12C Power Distributor LIMITED TIME FALL PROMOTION $200 Power Cord Credit + FREE Stainless Steel Isolation Feet ($249 value) The VENOM MPC-12 "C" is designed specifically for computer-audio, video and music-server based systems. Computer-media based music systems use several digital or processing components associated with computers (server). These devices are often made with commodity power supplies that put out significant amounts of power line noise. The MPC-12C was designed specifically to segregate or “firewall” the computer or video related components -- preventing them from polluting the performance of your high-end analog components. The MPC-12 "C" is Shunyata Research’s most finely tuned power distributor in terms of its system specific design and function. Essentially, the MPC-12 contains two separate power conditioners starting from the power inlet. In section one, The MPC-12 "C" uses Shunyata’s finest CCI™ (Component-to-Component Interference) filter arrays to reduce noise and enhance performance while still allowing for maximum current-delivery to even the most power hungry amplifiers. The other side of the MPC-12 "C", employs a custom-manufactured hand-wound air coil which literally fire-walls intense computer or video generated noise from affecting the components plugged into the second bank of six high-current/Analog outlets. This offer won't be around for long, so act now to save on one of Shunyata Research's latest power distributor that has been designed for computer audio.

  21. Finally, about a month after receiving my JS-2 and MMK from Alex, I was able to be home, have the tools, and the time to do the installation. Here are some of my thoughts... THE GOOD 1. I've just turned on the Mac Mini (late 2014 PCIe Flash) plugged into the JS-2 and it does sound really good (I can't quantify the improvement, but it's definitely there)! 2. Fantastic service and support from Alex (Superdad). I had a few questions over the past few weeks, initially with the order, and then some clarification questions, all of which Alex responded very quickly to! 3. Really nice build quality on the JS-2 (see picture below). I personally would have preferred not to have any text on the front fascia, but no biggie. COULD BE IMPROVED 1. I consider myself reasonably "tech comfortable", but even so I have to admit that I put off the installation project more than a couple of times because of the rather scary-looking documentation - granted, probably every step needed is described nicely by Alex in the little booklet, but it's in very fine print (a tad challenging for my nascent presbyopia), and there are no pictures! Not one (well, except for the cover photo)! 2. Having said the above, Alex did very kindly send me emails with iFixit links, for the tear-down (first part) of the installation. However, one will still have to read the documentation very carefully to figure out the second part, as it (of course) isn't on iFixit... 3. What made it a tad more worrying was that the documentation was obviously prepared some years ago - the very first line says "Install this product only in a 2010, 2011, or 2012 Mac mini". Alex did clarify in an email that it would work fine on my 2014 Mac mini, and did also describe some of the differences between the documentation and what I would have to do for my newer unit, but it did add to my fears (and the complexity)! 4. Another problem was that the Torx 6 Security bit, which is required to open the late-2014 Mac mini, is not included in the toolkit that Alex sends out, so I had to purchase it from iFixit separately. 5. There is no documentation at all as to how to use the JS-2. At first I didn't worry because, after all, there aren't that many connections! However, for the first few minutes after turning it on my Mac Mini refused to start up, until I figured out that the "sense" cable was loose, and also that I had to have the little switch at the back set to "sense", and that the DC cable had to be connected to the DC-2 output (in hindsight it is obvious, since it is the output closest to the "sense" input)... SUMMARY In summary though, I have to say that the actual installation process is very, very easy to do - it just looks difficult to those of us accustomed to having pictures to follow-along to! The resulting sound quality improvement (at least to my "freshman" ears) also sounds pretty good! And again, Alex was fantastic in being very prompt and helpful with his email replies! I've provided some photographs of my installation below, as it may be helpful for others in the future (do note that in the second-last picture the switch/sense is set wrongly - I took that photo while trying to figure out what was wrong). Art p.s. As mentioned, for the first (teardown) phase, I used this guide from iFixit:
  22. I have Z77 chipset, 2600k, Win2012, Everything is tight and optimized, with a USB3 PCI-E card, and just one Intel SSD. Feeding my DAC over USB (DAC has it's own power). Been changing from a Corsair hx750 and an corsair vx450w and listening to the difference. Even though the Vx450w is much less effective and older it sounds way more open and musical. The strong and muscular HX750 makes everything muddy and without snap. Am I just crazy? Ear-Fatique? Any others that have had the same experience? Monitoring: Beyerdynamic DT 880 Pro. - The HX750 shall have lower amounts of ripple and noise according to measurements. (!) Edit: (!!!) I might also get more jitter from my SSD drive according to HD Tune Pro. Could PSU affect Random Acess times on my SSD? Wow. 1. VX450W (PIC) -------------------------------------- 2. HX750W (PIC)
  23. Hi, New here, based in the UK. My old CD player packed up and a friend of mine who is a serious hi-end HiFi enthusiast kindly bought me a Schiit Modi. Since I have so much music on my Macbook now, and have stopped buying CDs, he said it would be a convenient way of listening to my collection. It arrived yesterday, with leads supplied. I plugged the leads into the back of the Modi and my amp (an old Rotel) and plugged the USB lead into the Modi and my Macbook and... Nothing... Zilch... Nada. The power light on the Modi stays off and nothing happens on the Macbook. I spent the morning using the Schiit troubleshooting guide, changed the leads, USB ports, input to amp and still nothing. Any suggestions? Sort of tricky, because I don't want to contact my friend (it seems a little ungenerous since he was kind enough to buy it for me) and i don't know where he bought it. Of course, if I have to, I will, but would rather not. On a relatively new Macbook (OS 10.7.5). Tim
  24. Venom MPC-12A and MPC-12C Power Distributor Promotion MPC-12C & MPC-12A Promotional Packages (starting at $2139): Tax-Season Savings! The VENOM MPC-12 is similar in function to our traditional power distributors in that it is intended for normal audio and video systems that are not specifically computer based audio systems. VENOM MPC-12C The VENOM MPC-12 "C" is designed specifically for computer-audio, video and music-server based systems. Computer-media based music systems use several digital or processing components associated with computers (server). These devices are often made with commodity power supplies that put out significant amounts of power line noise. The MPC-12C was designed specifically to segregate or “firewall” the computer or video related components -- preventing them from polluting the performance of your high-end analog components. The MPC-12 "C" is Shunyata Research’s most finely tuned power distributor in terms of its system specific design and function. Essentially, the MPC-12 contains two separate power conditioners starting from the power inlet. In section one, The MPC-12 "C" uses Shunyata’s finest CCI™ (Component-to-Component Interference) filter arrays to reduce noise and enhance performance while still allowing for maximum current-delivery to even the most power hungry amplifiers. The other side of the MPC-12 "C", employs a custom-manufactured hand-wound air coil which literally fire-walls intense computer or video generated noise from affecting the components plugged into the second bank of six high-current/Analog outlets. VENOM MPC-12A The MPC-12 "A" has two independent zones of 6 outlets each, for a total of 12 outlets. This allows for the normal segregation of analog and digital components or between amplifiers and source components. The "A" designation stands for audio although it can also be used in all forms of audio/video systems. The two isolated zones will be labeled "A/V Zone 1" and "A/V Zone 2”. At the core of the MPC-12 "A"are Shunyata’s latest generation of CCI™ (Component-to-Component Interference) filters. These powerful multi-frequency noise-filters provide exceptional isolation for electronics without interfering with DTCD™ (Dynamic Transient Current Delivery) or electronics power supply function. The MPC-12 "A" has none of the drawbacks commonly associated with traditional forms “power conditioning” yet provides all of the protection and noise isolation that benefit electronics systems of all types. Complementing the superior noise isolation in the MPC-12 "A" are dual 12 gauge OFE 101 copper conductors. This massive 9 gauge aggregate conductor set insures optimum DTCD™ performance for any and all high-current draw systems. Surge and spike protection are included in the form of Shunyata Research'’s Surge module, which has had a virtually zero failure rate since its inception. Putting these elements together in a 12 outlet, form-follows-function package makes the MPC-12 "A" an incredible value. For those looking at the next big step-up from Shunyata Research’s critically heralded PS-8 power distributor, the MPC-12 "A" delivers on that promise. For those with the audio-systems that combine one or two digital components such as a CD player or Transport and DAC, the MPC-12 "A" model makes the most sense. For those with computer audio or video centric systems, the MPC-12 "C" is the best choice. The MPC-12 “A” and “C” models also feature on-board surge, spike and over-current protection with a built-in status L.E.D. indicator. For a limited time, we are offering complete high-performance power-distribution packages on the MPC-12 series of power conditioners. These are available on both the MPC-12A and MPC-12C. This all-in-one package includes the high-performance option of the High-Current VENOM-HC or ALPHA HC power cable and the new SSF-38 (stainless steel feet).

  25. Hi... I've been using an Regen/idac2 combination with the USBridge just fine. I'm using the standard USBridge PS powering both the Sparky and the hat. idac2 is USB powered, and is NOT on the list of compatible DACS. Last night, I removed the Regen, and plugged the idac2 directly into the USBridge. No lights on the DAC, a quiet, clicking sound from the USBridge...and no sound of course. Restored the Regen and all is well again. Questions: Since it works with the Regen in place, and therefore powering the DAC, might the problem be that the current requirements of the DAC exceed what the USBridge can supply? I see, though, from the compatibility list that the ifi idsd IS compatible, and it similarly contains a headphone amp, so I would guess that the current requirements are similar. Given that the USB data from the USBridge is so clean, I'd like to at least try it without the Regen. Any suggestions as to how I can accomplish this would be appreciated. I'd be happy to get a separate PS (probably an iPower) for the USBridge, if that will address the problem. Many thanks... Michael
