  1. I have a Ghent custom built cable using 16 AWG Gotham wire and the JSSG360 shield between the SR7T and TAIKO DC DC ATX currently. It works really well here.. (Note - It runs a full length of wire for each Molex pin- so heavy gage) I will get some of that Deulund wire to try out for the EPS as it seems to be on sale - wish it was 18 AWG (more useful all around) Thanks for the tip. ATB. b.
  2. Here is a brief update. I believe the TAIKO DC-ATX is clocking well over 400 hours of play: Switching back to the SRT7T powered HDPlex 800 reveals that the volume change is hardly noticeable anymore. The TAIKO has indeed opened up nicely and is quite punchy with all the other comments above still valid! The SR7T-HDplex DC-ATX with the SR7T-SJ regulator to the CPU is the fine tuned setup having had much more time with it. It gives a very relaxed fluid sound but with the slightly 'submerged' detail in comparison (for lack of a better way to express this)! In
  3. If you watch it on youtube there is a list of the materials/equipment used
  4. The TAIKO DC DC-ATX currently mounted on the HDPlex faceplate. Four M3 holes were drilled through & tapped.
  5. The Ls increase the output impedance I imagine, an effect which @Nenon felt was detrimental to the TAIKO converter performance? The other advantage of the L-C (choke input) is a reduction of inrush current. I saw (Apr 1987 AUDIO AMATUER) a rare topology with the L on the AC side of the rectifier. I wonder if @prinz could model this one. It should reduce the peak rectifier current, the inrush current. The core of L would be AC powered - saturation less of an issue. Unfortunately the output voltage will be less. In the end though best SQ for the PS is the goal here.
  6. Anyone ever try these caps? I see them used in some pricy LPS (NAIM 555PS) Exxelia - FELSIC 039 (Capacitors > Aluminum Electrolytic > Screw Terminals) Datasheet felsic-039-v4.pdf (exxelia.com)

That link points to a micro ATX form factor - mini ITX : GIGABYTE Z390 I Aorus Pro WIFI - Intel Z390 Motherboard Overview: 50+ Motherboards Analyzed (anandtech.com) comparison tables can be found here: Choosing The Right Z390 Motherboard - Intel Z390 Motherboard Overview: 50+ Motherboards Analyzed (anandtech.com) ATB b.
  8. Still very fresh, less that 40 hrs, a long way to go from what you say! It will be running 24/7 for sure. I will compare the volume thing to the HDplex 800 again at month's end. Welcome back safe and sound I hope. ATB b.
  9. I will also confirm preference of using the SR7T to power the TAIKO DC DC ATX unit and let that power the CPU (Intel i9-10900K in a GB Z490 AORUS Master). The music flows (grabs my attention) much better than when using the 2nd rail via a SJ regulator for the CPU. So far I hear what I would call a 'polished' sound, pleasant on the ear with nice PRaT. Music intricacies are very evident. Instrumental timbre is very good as are voices. This is very relaxed listening so far. I switched the SR7T powered HDPlex 800 out to test the Taiko. The CPU powered by the SR7T in both cases. I ha
  10. My experience with PHD (2020) mostly quoted from a PM I had with a member here: I had originally ordered a custom variable voltage DR from Paul for a server/endpoint setup. That was taking too long and I was not happy with his sporadic communication. At my age I was not willing to wait another few years for the PS. When PHD started making the standard one I gave up the custom DR order to someone else at the earliest opportunity. I then ordered the standard SR7 dual fixed 19V rails. At the time the turbo option did not exist. In that process there were other delays inc
  11. I would also like to mention that dealing with Steven at PHD was a real pleasure. He worked hard during a challenging pandemic and was very responsive and helpful, and built me a great SR7T. I thank him and wish him well in his future endeavors. Simply having a great product does not insure success to the company built around it as is evidenced here. You need some business acumen with the customer satisfaction as the central theme (and some luck). Mr. Paul Hynes is brilliant at design and making these power supplies. It would be a pity if it all ends in failure. I do wi
  12. @Gurkel Perhaps as suggested by others you could start a thread on the topic of your choice. There are many knowledgeable and friendly people here who might share their thoughts with you. In the end though SQ is what is, subjective and individually experienced. No one can convince you theoretically or otherwise of what you hear or like for that matter , or what you will hear from any specific build. Start with what makes theoretical sense to you (you will not be the first nor last one) , and take it from there or end it there! As for me- curiosity, with the help of som
  13. That is the question! In part it seems that most DAC designers are not able yet (have tot figured out how) to mitigate all noise on the input digital signal, which seems to affect the analog converted signal in various forms. Whatever the case it seems that when you have low noise power supplied to a 'super computer' as you called it, idling most of the time and achieving low latency when computing from both the h/w and a streamlined OS - you have a good result for SQ. Punch (macro dynamics) , 'silent' background revealing more detail, longer (fuller) note decays, timbre etc all evidentl
  14. Got it - thank you. Happy testing. ATB. b
  15. Thank you for your observations. The Cons of A you mention are of concern to me too. 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. 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 in
