It would be great to try first then buy if the value proposition is right. I would invite you over for an audition but I am NYC based 😁. The improvement in my system has been worth the price, having purchased more expensive amps/preamps/dacs etc. Again, my situation is unorthodox as I have no cards externally powered via LPSU (most people here do) so perhaps the difference in my system is far greater than those with DC4s/DC3 or other high quality LPSU powering their network card/usb card. I will get around to testing that in the future if there is interest in doing so. Link to comment

EOT Absolutely. FWIW my experience only compares the Taiko to the HDPLEX DC-ATX. The Taiko solution is the better of the two. I cannot imagine the HDPLEX providing superior performance for people who prefer to cut costs and go with a single more powerful rail. I am not qualified to claim the Taiko DC-ATX is the end all be all solution for every build. It was certainly not my intention to do so. That being said, any tests we conduct should be taken into proper context as well. The Taiko DC-ATX + Unregulated linear supply were voiced for Taiko DIY server build.

Popular Post Exocer Posted April 15, 2021 Popular Post Share Posted April 15, 2021 Getting back on track: I have decided to give this setup a few days to settle in before providing detailed thoughts. What I will say is this certainly does sound different than 19v + 12v (to EPS) and I do not know how much of that difference comes from the use of the Ghent cable. This is an apples to oranges comparison so take from it what you will :). Is it a good or bad difference? I do not think it is fair to say just yet. One thing is for sure, the 19v 10A SR7T can peacefully provide stable power to a full ATX motherboard, CPU, Optane drive, NIC, USB card without a hitch. Will share more details in the coming days.

Exocer Posted April 15, 2021 Share Posted April 15, 2021 Guys, Have we started looking at Gen3 Xeon Scalable CPUs? What we have below looks like a newer alternative to the highly hailed Xeon Silver 4210 CPU: https://www.intel.com/content/www/us/en/products/sku/215283/intel-xeon-silver-4310t-processor-15m-cache-2-30-ghz/specifications.html Here is a comparison between the 4310T and 4210. The 4310T is a 10nm design running at a slightly higher base/turbo clock speed. The interesting part that we may all benefit from is a larger cache! 13.75 to 15mb. The downside? TDP appears to jump to 105W but with none of us planning to upsample with these Xeon Builds we should be fine. Another downside: A new socket :( Back to the ol' motherboard hunt. Also, I am assuming that this CPU will sound just as good as or better than the 4210. It is never good to assume. Perhaps there are other good discoveries to encounter. I suspect Asus motherboards similar to the C621 sage will be a good place to start once they become available. Nenon 1 Link to comment

This raises an interesting question. I am almost certain my speakers sound nothing like yours. I would describe my system as neutral with moderate efficiency and moderate to low overall power in terms of amplification. Rarely do I find myself listening above 80db from seating position (ok, the occasional 85db on a Friday night). My speakers aren't the most efficient or fast, but they do keep up with most complex passages (more so now with the improved source). They provide extension down to about 30hz with authority from seating position. Overall, there is a reason i've had them in use for 15 years and have made incremental upgrades to them along the way. I'm not the best with describing these traits but how would you describe the character of the system used for voicing the DIY Taiko server project? What characteristics about the Toroidy did you perceive to place it in 2nd place? The reason I ask is I (and others) may find that those traits are more synergistic with my particular preferences, or, it may offset deficiencies in other areas of our system. Just some food for thought. Cheers MarcelNL 1 Link to comment
Popular Post Exocer Posted April 18, 2021 Popular Post Share Posted April 18, 2021 Back to Taiko DC-ATX testing with PHSR7T. Let's label the configurations A and B. Where: A. Taiko feeding entire server, fed Paul Hynes SR7T 19v 10a rated single rail. Ghent Gotham JSSG360 from Taiko Dc-ATX to EPS on motherboard. B. Taiko feeding ATX only. EPS powered directly from a Paul Hynes SR7t 12v 12a rated rail. All using the best of Paul Hynes best silver DC cables. No JSSG. Solution A: Pros 1. Amazing transparency. 2. Sense of space is more open. 3. New microdetails are heard and are surprisingly at the forefront. These details cannot be unheard when switching back but did not draw attention to themselves in the same way. 4. The sense of more information retrieval. There will be moments in your listening where you are shocked to re-listen to a very familiar song and will hear a series of notes in the background that you did not know existed! It is something to experience for sure. Cons 1. The sound is a bit leaner and i'm a sucker for a "full bodied" sound. (my preference) 2. More noticeable sibilance over time. I am convinced this has more to do with the EPS cable than the Taiko DC-ATX. 3. Not as much sense of ease. Perhaps I was approaching the 10A limit or not staying within a comfortable range. 4. Down a few notches in slam/impact. Solution B: Pros 1. The sense of ease you get with a dedicated clean 12v rail is apparent. 2. More slam and visceral effect in hard hitting songs. 3. Sibilance is completely not an issue, especially with female vocals and sharper sounding songs. 4. Fuller bodied sound with no obvious loss of speed. Cons 1. The sound does not have the same openness as Solution A although I would not consider the soundstage smaller or closed in. 2. Ultra fine details are not as audible and do not draw as much attention to themselves although they are present (after they jump out at you with Solution A and you cannot unhear them). 3. You kind of miss the magic of solution A depending on the song Summary In terms of musicality it is a toss-up. Please keep in mind that the cables are not entirely equal and I have had sibilance issues with the Ghent cable in my system before. With the cables I have on-hand I would prefer Solution B for longer sessions, but Solution A has a Lot of potential and it has this way of drawing you into songs you know very well. I would be curious to see how Solution A would work out with a higher capacity rail and/or an equal quality EPS cable. Is the Taiko DC-ATX worth it as an upgrade from the HDPlex? In my particular setup I took a risk and ordered it not knowing what to expect...and it was a major step in the right direction. The HDPlex is good, the Taiko is astounding in comparison, even for ATX alone I feel it is a worthwhile upgrade. Follow-up: In the near future I will be building another EPS cable made from the same wire we will use for our unregulated linear power supplies. This cable is known to be very neutral so the hope is that I can conduct a fairer comparison between solutions A and B. Hopefully you all find this useful!

Those are much harder to power than a single 65W TDP AMD Ryzen CPU or a 95W TDP I9 9900k. And that is where this power supply arrangement really shines. I am not sure how well it works on lower power CPUs. I am guessing on low powered CPUs a good LPS would work better. But this dual CPU computer is a different story. Those are some experiments people would need to make. There are specific applications in which we want to use the Taiko ATX. It's not a miracle device that would work best in every single application. 4. I find the GaN Fet ATX to be extremely fast. Too fast actually. Adding some big capacitors in front of it makes it fuller, more dynamic, and more expansive. It also slows it down a little, although it is still faster than a LPS. Seems like this is one of the things @Exocer ran into. @Nenon, thanks. Do you have any interest in testing the unregulated supply + Taiko solution with your i9 rig (if its still around)? It would be an interesting data point for those who plan on sticking with single CPU builds for a while. In the future I will test whether the unregulated linear supply + Taiko Dc-ATX will surpass the two high quality PH SR7T rails. That would not be an apples to apples comparison since my SR7T only outputs 19V DC, so considering the impact voltage has on the Taiko DC-ATX it would only serve as a way to compare what most would have on-hand (at least a single high quality 19V regulated DC rail) to a dedicated unregulated supply voiced to work with the Taiko DC-ATX/Asus Sage C621/Dual Xeon Scalable CPUs. This is still a worthwhile test to conduct for the community. Another test to conduct would be powering just the CPU from the PHSR7T and ATX from the Unregulated supply + Taiko. I would think this would get a bit tricky and may introduce grounding issues if not careful. The more tests we conduct, the better. With the right EPS cable perhaps Solution A (Taiko powering everything) will work better for me. I am very picky about the high frequencies. Maybe an issue elsewhere in my chain is revealed by the Taiko. There are so many variables to keep in check and to take into proper context when testing and making comparisons. I have switched to Qobuz today and I will be conducting a similar test to the previous one in the near future. I will probably keep both Tidal and Qobuz since Qobuz did not have some of my favs. Cheers, -Rob Link to comment

Popular Post Exocer Posted April 20, 2021 Popular Post Share Posted April 20, 2021 Hi All, In light of the recent dialogue around power supplies I decided to reach out to Paul to get his take on unregulated supplies. As a happy SR7T owner I am still open to trying the new Unregulated supply with the TAIKO DC-ATX and chances are I will be keeping both power supplies around regardless of the outcome of my tests. Here it is: "... Lets go through your questions :- Fast transient response requires speed from the regulator circuit design. Mosfets are blazingly fast and have much wider bandwidth compared to bipolar transistors so I use Mosfets in the regulator output stages. Driving Mosfets at very high frequencies can be tricky but with a little care in the design of the driver circuitry exceptional transient response and bandwidth can be achieved. Also keeping the Mosfets and the driver circuitry stable at frequencies approaching many hundreds of Mhz can be tricky. The circuitry I use for this has been carefully optimised to provide very fast transient response, whilst minimising transient overshoot and ringing (critically damped). Many voltage regulator designs utilise a number of gain stages to increase the available feedback to use for output error correction. This can be a can of worms as the more stages used the more frequency compensation is required to keep the design stable. This has an adverse effect on operating bandwidth, the transient response time and the settling time. The regulator design used in the SR7 has only one gain stage in the error drive amplifier directly feeding the output Mosfet. This provides a tight loop around the error amplifier and output mosfet that does not require frequency compensation for stability and the resulting phase margin is excellent and such that the design is load tolerant and not prone to parasitic oscillations. I have used this regulator circuit to drive anything from large low ESR capacitor banks to inductive loads like field coil loudspeakers and I have not managed to initiate instability. It works very well with both analogue and digital loads (as you are finding with your SR7T). The very low wide band output impedance from the regulator output stage is capable of excellent load damping so HF noise feeding back into the regulator from the load is well suppressed. The load regulation performance is very good as the error amplifier is fast and can drive the Mosfet well. One point I will add here is that many power supply products on the market have rather abrupt current limiting applied to the output stage. This is fine if the load never demands currents exceeding the current limit but can cause all sorts of problems with loads demanding high transient current delivery. Transient current starvation is one likely cause for problems with motherboard boot sequences and program dropouts when the current limit of a supply is exceeded. The rated load current in your SR7 high current rails would be specified for say 19v 10A or 12v 12A continuous depending on which modules have been fitted. The voltage regulator error amplifier is capable of providing enough voltage between the gate and source terminals of the output Mosfet to deliver transient currents up to 50A into the load (I specify 40A transient to allow for device manufacturing spreads). The regulator circuit design is easily scalable for higher continuous and transient current delivery although the thermal management does require rather larger heat sinks (and larger mains transformers) than the ones in the SR7T chassis. Such products are in the production engineering phase at PHD Ltd at present. I specify the PSRR of the SR7T voltage regulator as >80dB (once again to allow for device manufacturing spreads) from DC to 100 KHz with a gradual roll off above this frequency. This is not the whole story of course as the mains transformer is configured as a balanced isolation transformer providing good common mode rejection of incoming RF interference and the energy storage capacitor bank also has a very low impedance, especially at higher frequencies due to the very low ESR of the capacitors arranged in a parallel array. The SR7DR (double regulated) power supplies move the PSRR up to around 150dB from DC to 100 KHz. The PSRR specifications apply to ripple breakthrough and also form part of the noise specification. There are a number of steps taken to reduce the regulator circuit noise. Firstly a very low noise voltage reference is used to feed the error amplifier via a noise filter which provides an exceptional low noise reference. I specify the error amplifier devices having a noise rating of 0.5 nanovolts root Hz but this is conservative as they typically measure around 0.25 nanovolts root Hz. This is a lot quieter than the Linear Technology voltage regulator chips that are currently popular in power supply designs. The composite error amplifier/output stage has no noise increasing voltage gain so the noise levels are typical across the range of output voltages of the regulator modules. I have been through a phase of working with high performance unregulated power supplies back in the 1990s which can work well especially when compared to older style integrated circuit voltage regulators with limited bandwidth, transient response time and settling time. However historically I have found that it is possible to design voltage regulator circuits that offer better performance than unregulated linear supplies generally, although knowledge increases with time and better components and materials can make a difference so I would be reluctant to state categorically that active linear supplies can be a better solution. I would have to conduct extensive testing and listening trials before forming any conclusions currently. Out of interest I have spent 41 years specialising in audio power supply design and I can say from experience that inadequate design of voltage regulator circuitry can severely limit performance. I touched on this subject in a series of articles published in underground audio magazine “Common Ground” during the 1990s. I have attached an updated copy of these articles for you to read. You might be surprised by the overall conclusions discussed in the articles as they also discuss power supply system design for the lowest inter-stage interaction. Unfortunately it would be unlikely that current motherboards could be adapted to this philosophy on a DIY basis although separate EPS power connections from the ATX power connections are a positive move in this direction. Also of interest, over the 41 years I have been researching power supply systems I have found that no amount of audio component “bling” can compensate for an inadequate voltage regulation circuitry although it can enhance performance of a good voltage regulator design. Heavy load current changes on the SR7 outputs only produce small output voltage changes and static circuit noise remains the same at all output currents within specification. Nothing is perfect and it would require an output impedance of zero Ohms at all load operating frequencies to have no output variations, which is currently not possible with any available technology I am aware of. I hope this helps. Regards Paul" bit01, auricgoldfinger, lwr and 7 others 4 6 Link to comment

I should be getting one Taiko DC DC-ATX in the batch shipping 4/30 - I will pay special attention to that and hopefully report back sooner than later. Looking forward to your feedback as well! Solution A is by no means unlistenable. I will test again with a new EPS cable in the near future. 32 minutes ago, bit01 said: That Gotham GAC4 mic cable heavily rejects RF - that will not be the case with the PH cables I suspect. I don't have it for EPS though so cannot comment specifically on that (I have the Neotech 7N UPOCC one). As you well know it is difficult to reach isolated conclusions in a non controlled test environment due to the permutations and combinations involved. I do not think it is the GAC4 Mic cable in my case. This is the cable: https://www.ghentaudio.com/pc/gt02.html The PH cables are arranged in a way to reject RF but I do not know how effective they are at doing so. Either way, I do not hear more "noise" with the PH cables going from PH SR7T 12V out to EPS in so I am not inclined to believe that is influencing the sound much. As I said in another thread, we are comparing a single shared 10A 19v rail to the use of both a 19v 10a and 12v 12a rails. This should definitely be taken into consideration and may account for some of the observed differences in addition to the EPS cable. Here is a response I wrote to another concerned user: "For those with a 19v rail (For output into DC-ATX) + 12v rail (for EPS) that are not looking to go full linear for every rail, the Taiko DC-ATX is a major improvement over the HDPlex 800W. If you are using a single 19v rail you may want to invest in the higher voltage Unregulated LPS which was designed to partner with the Taiko DC-ATX as this is the optimal configuration for the Taiko DC-ATX. Or, you may want to go full linear per Marcin's Optimo ATX (I have not heard this unit yet but I trust Marcin's ears). Or you may still go with the Taiko DC-ATX with a single high quality 19V rail. In my tests, I can only say the SR7T 19v input per the synergy with my system did not work as well as having EPS powered by a direct 12v rail and that could very well boil down to a particular cable I have never been fond of in my system that I was forced to use for Solution A testing, or perhaps there was less current for the CPU available, too many variables changed from Solution A-B to rule out the Taiko as the issue. Soon I will conduct a re-test of Solution A with a different EPS cable and report back." NanoSword 1 Link to comment
Popular Post Exocer Posted April 29, 2021 Popular Post Share Posted April 29, 2021 Hey all, I tried some new parts over the last week or so. Elfidelity AXF-107 - As previously noted, the AXF-107 does not fit the Hdplex H5 case unless you cut off the side you do not intend to use. I tried this card for about 5 days or so until removing it today to perform a sound quality comparison. I used the smaller output. In my system, the card sounded good, but it didn't suit my listening preferences. The good thing is it did not sound bad from day 1. Transients were not as sharp, the soundstage changed in that it was not as well defined. The sound was a bit soft and closed in compared to what I prefer. This card will work well in a system that needs to be tamed due to existing harshness (I have none). In my noisy desktop/headphone setup I think this card will work wonders so that is where it will end up (as I do not do much critical listening there). 670p SSD In an effort to separate my music files from my OS drive, I purchased the 670P. The value proposition is great. I have no complaints about the sound with Euphony. The board being Z390 based does not have direct to CPU M.2 slots so I am indeed using this through PCH. With buffering enabled I wonder how much SQ I am losing for local playback compared to standalone Optane in this duty. I have yet to try the 900P, but, these 660-670P drives work pretty well. I do not audibly sense a major increase in noise over the Optane for local playback. Cheers, -Rob Topk, NanoSword and StreamFidelity 3 Link to comment

Popular Post Exocer Posted May 6, 2021 Popular Post Share Posted May 6, 2021 I've been testing the 19V SR7T rail again to power the entire server (Today) and I wish I could redact some observations from my previous post. This sounds great Vs 2 rails: 1. There is absolutely no harshness or sibilance (I have been listening for 1.5 hours now) 2. Dynamics are where they need to be 3. No thinness to report 4. Soundstage is about the same size So for those who do not want to go with the unregulated LPS and already have a PH SR7T/DC4 LPS I highly recommend the Taiko DC-ATX to power both ATX and the CPU. No, I have not switched out the EPS cable yet. Some changes in my system since the first test: 1. CPU now runs at 4.5ghz (up from 3.8). 2. Tests were conducted with music files and OS on separate drives. 3. I've downgraded my Tidal subscription and listen mostly to Qobuz. 4. Perhaps the Taiko DC-ATX is appropriately broken in after several weeks of use. 5. Upgraded to a newer better sounding version of Euphony Stylus I think i'll be keeping it this far for a while. The issue was elsewhere in my chain. It'll be nice to have an extra 12v rail :) Cheers, -Rob ASRMichael, Dev, Iving and 6 others 2 1 6 Link to comment

Admittedly the Taiko to EPS is via the bog standard one that came with the Hdplex. My advice would be to get away from that bog standard cable ASAP. That is most definitely your bottleneck. Also, my Taiko took more than a few days of continuous use to break in so definitely check back in the future with a better cable. NanoSword 1 Link to comment
Popular Post Exocer Posted May 16, 2021 Popular Post Share Posted May 16, 2021 @Nenon thanks for the update. Very excited about all of this new information and still processing it. Given my current server spec, V3 may be overkill but it will certainly provide a solid foundation for future builds so that is what I am leaning towards. Hopefully it will fit in the Modushop chassis. As for drilling the bottom panel holes, I was willing to draft that up in CAD in addition to the rear panel (which is already semi-complete, just awaiting your signoff) so that all the DIY community would need to do is attach both the rear and bottom panel files to their chassis order to receive a fully drilled out case. My entire transaction was through DIY Audio store though which offers plenty of Modushop cases. (I only drafted the rear panel for my DC3 chassis as I had no idea where the bottom screw would go, so I ended up drilling those using a household drill). Looking forward to a PHSR7T vs Unregulated LPS V3 bake off. Can we give these supplies a better name? Unregulated LPS V3 is too generic and too much to type 😁.
