MarcelNL Posted February 26, 2021 Share Posted February 26, 2021 I'm not so sure anymore that a SMPS cannot compete with linear, we're talking high current here and if there is one thing linear PSU struggles with it's high power. I would LOVE to be able to compare the Taiko ATX to a well reputable (or home grown) linear PSU versus the Corsair AX 1600 as it's 100Mhz switching freq should put interference/noise well out of the trouble zone.

kelvinwsy Posted February 26, 2021 Share Posted February 26, 2021 I hv thought of this device too.. the fuse will likely slow the transient current delivery but my main concern is how to feed big current supply to the 12v connector? why not just use an extension 24pin ATX cable.

Sounds pretty good to me, but I bet you that the better quality power supply still wins. Corsair SFX750 is just a decent stopgap to true linear IMO. IMHO it's still a viable alternative for those of us who just wanna have a glimpse of what Taiko Audio Server + custom ASIO driver for Thesycon / XMOS really is all about once they're available at some point. Maybe not everyone would go for that Taiko ATX + PSU + chassis + heat sinks + USB card combo (for obvious reasons) while in theory the "bare minimum recipes" should be no slouch 1 ✕ chassis (active cooling) for motherboards with EEB form factor 1 ✕ Asus WS C621E SAGE motherboard + 1 ✕ ATX PSU for feeding 24-pin ATX 1st Xeon Silver octa-core CPU + 1 ✕ ATX PSU for feeding primary 8-pin EPS 2nd Xeon Silver octa-core CPU + 1 ✕ ATX PSU for feeding secondary 8-pin EPS Active cooling solution for 2 ✕ CPUs @ 85W TDP 1 ✕ Windows 10 IoT 2019 LTSC License 1 ✕ USB DAC / DDC with Thesycon U-HEAR or XMOS XU-208 / XU-216 etc. The whole point here really is all about getting something that's gonna be able to run TAS without having to break the bank, while IMHO it might be very difficult (if not impossible?) to achieve the same level of SQ by opting for a different config (i.e. nothing else is able to run TAS) with a single AMD EPYC / Ryzen / Threadripper or Intel Xeon / Core processor. Of course we could always figure out what components could be upgraded / replaced down the road. Gavin1977 and Exocer 2 Link to comment

I did. It took less than 10 seconds to realize that there is no comparison. They are on completely different levels. The Corsair AX1600i just went back to the gaming system it came from. It belongs to a gaming system, not my music server. I asked Emile if he knew why. His answer was "The AC side sucks". Apparently, I was way behind on these experiments than him again :). No surprise there. I could not open and mess around with my friend's PSU, but I asked Emile if we could try modifying the AC section on the AX1600i, but he did not think it would be easy or worth it, because of the way it has been designed (i.e. feedback loops, etc.). Remember I wrote that every wire and every capacitor on the unregulated LPS + Taiko ATX made a difference? I have spent quite a bit of time tweaking that part to my taste. Maybe I did not mention how much of a difference rectifiers made? Yes, the most expensive Cree diodes I tried sounded the worst of all. I am back to cheaper Schottky diodes (similar to the ones Sean Jacobs uses), and they sound a lot better. I even tried a FET rectifier without diodes... It all makes perfect sense to me now after this experiment. What was I thinking :) ? I guess that maybe the AX1600i would be very close to what I use now... It's not. If you are using a bad LPS, the AX1600i would be an improvement. My guess is that it also sounds better than most other computer PSU units. Perhaps a PS Audio P20 power regenerator and one of these might give decent results. But there would be a noticeable level of noise and harshness still. So there is that.

MarcelNL Posted February 27, 2021 Share Posted February 27, 2021 Thanks, that was indeed the sort of comparison I was hoping for! At least my comparison of a 400W PSU and a 1200W learned me a lot, and both will find their way to other systems once the Taiko is revealed. Schottky's always did well for me in audio and many sound real good with only nuances between them. Diodes are a mine field, you really need to audition them, great that you tried the expensive Cree's and the FET, that takes two out of the equation.

The PSU's spec's show droop rate performance under load and in particular the ripple and noise specs would be a concern. And there can also be combined noise issues with an SMPS followed by DC ATX buck conversion. The specs on the supply linked show: Droop Rate (-xDx-R suffix) 50 mv/A Ripple & Noise 400 mv (Both for the 28v version). They are big figures for feeding a DC ATX in a server that's focused on sound quality. I spent quite some time a few years ago looking for a SMPS solution to power DC ATXs. There would be much going for such a setup if it could produce really good sound. None that I looked at worked well feeding DC ATX's for sound quality however. The problem came down to having two unlinked switching controllers, one in the SMPS and a second buck controller for each rail of the DC ATX that followed. Both of stages vary switching frequency and or duty cycle as they see fit to track the current load being consumed by the PC. The result for the combinations looked at was mess of noise both on the input to the DC ATX and on it's output. On the DC ATX outputs there was a combination of the harmonics of the switching frequencies of both stages. Never manged to get a nice sound from the combinations tried. If you can, perhaps stay with regulated linear or passive filtered power. It's a well trodden path but for good reason. Something with droop under load in the very low mv/A range and combined noise plus ripple of <5mv. Transient response isn't quoted for the linked PSU but if it is published for another supply a <100us recovery time for a transient of 5 amps would be a decent place to start. OAudio Ltd.

If the Taiko DC-DC ATX is as good as described with regards to noise and ripple rejection then it will be interesting how it performs with a SMPS like this. Like Nenon says though, the Taiko DC-DC is so transparent it will sound different depending upon what is used to power it. Will the Taiko ATX be supplied with a set of cables? I'm just thinking that many people are awful are crimping cables, I still prefer premade ones to avoid any poor connections. MarcelNL 1 Link to comment
