  1. Yah, that article I have read but it won't apply to you since you don't have the pinkfaun streamer I presume. I do use the Pinkfaun USB bridge so that may explain my superior performance on my PC. The SOTM is obviously not state of the art server/streamer. Now if you are able to stream out of the SOTM with COAX that woudl be a more fair comparison. I could also get a Pinkfaun Coax bridge but that should make my PC sound even better than via USB and so makes the CEC even worse. I have to say I have not used 16 bit file on my PC and if I do so CEC probably would beat the PC. 16 bit on PC is not that great (if no upsampling running NOS on DAC). Regardless, I do like the CEC player CD sound, that is perhaps more relaxed even though resolution may be less. It probably still has less "digitalis" overall, and can sound damn great (for 16 bit or any bit!) The dynamics of 24 bit surely beats 16 bit, that is a fact, but despite this, the CDs still can be quite dynamic!
  2. I also have a CEC transport and it can sound amazing! Now I have compared same recording on my HDplex PC vs the CEC and the PC beats it clearly - however I believe the CD itself is of inferior quality too and I have Mediocre AES cable. Also the music files on PC is 24 bit and I use NOS DAC. Also my CD transport is an older model and probably not as good as before. Did u use the same recording to Test?
  3. I also use pinkfaun USB bridg, no issue but u think that priority change to the usb bridge would help with SQ?
  4. Interesting, I do not have much issue with the Corning USB optical cable. I did use the Regen USPCB to block off any leaving Vbus current which helps a lot. I tried using a isilencer or some EMI USB filter after the corning Cable but that made things worse. The Corning optical beats my copper USB big time, despite being 10 M long! (they don't make shorter than 10 M) But then USB may be quite different form ethernet cable.
  5. Depends on what you are doing I suppose. Are you planning on upsampling, resampling from PCM--->DSD, doing DSD256 and 512, Are you using HQplayer ? Are you running RAM with all your programs including the OS, eg Audiolinux on RAMROOT, ? Normally if you just download the entire music file to play in RAM, 8GM RAM is enough, as I do and I also do HQplayer PCM--->DSD256, and that is fine too. Obviously if you want to do gaming then that would be a whole different matter.
  6. I ended up abandoning the Noisy MacBook and built my own PC using HDPLex (well have someone built to be more precise) using Ryzen 2700x an 8 core professor. More than adequate for my needs. 8GB RAM is fine with me.
  7. Not sure if u have done so, but u may need longer warmup time for optical setup due to the need for conversion from electric to optical and vice versa, at least from my own experience with optical USB
  8. Hmm, since I do the at times upsample or do PCM--->DSD with HQplayer, I am using the higher CPU, just in case. I was told with my HDPLEX 200W ---> DC-ATX I need 10 A at least to be sure. You should check with the computer experts who build computers what is the minimal requirement for your Ryzen CPU. Mine is 2700x that already uses quite a bit of power if running full capacity (which I never do). If you use those 3000 series or 16 core etc... you definitely should make sure your PS has enough juice, even if not doing crazy upsampling. I think the sound would be beneficial if you use a PS that is just a bit more than you need rather than barely enough for the job! (just my hunch, no proof)
  9. Thanks for your great summary, (even if a bit off topic) but I think it is quite important to understand the close relationship between the music player/server and LPS or other PS. I use a very similar system to yours, also a gaming motherboard (x370) + Ryzen 2700x CPU 8 core., high cache. This setup was recommended by Pinkfaun, and I also got their USB bridge. The main reason to get this high power is to make sure I can do DSD and resampling/upsampling even though I rarely use them, and it turns out the high CPU may be the way to go to play nicely on all types of files. I have no issue with DSD256 (the most demanding format) and may want to do DSD512 in future and also M-ch DSD256. SO Pinkfaun recommended high CPU. They also recommended Farad PS but of course they share the same developers hence has business ties. Pinkfaun also thinks the higher cores are best for audio so less multithread is required. Like you, I find my vinyl gig not as spectacular (feeling sad actually...) though I have not been optimizing the vinyl setup for a while. I find myself looking forward to listening to pure digital sound from PC for the first time! I am no longer missing vinyl, or CD or SACD anymore. Now each format has a special character that from time to time I like to get back to and the vinyl's natural analogue sound is something very special. But the digital sound on the super PC with euphony OS is really something. I use the HDPLEX 200W which supposedly is only mediocre but still there is really not much digital glare/harshness anymore and sound stage is amazing, that it is really getting close to analogue sound, with the added detail and clean sound. Now provided you have decent recordings as crappy recordings will still show its digital flaws. Right now Farad which I think uses some ultra-cap like design can only do 3A but up to 24 V which I suppose would work for these gaming motherboards/CPUs. Obviously with high CPU, a nice quiet efficient PS is very important, to make the whole setup works. I think the Sean Jacobs PS are really quite promising. I may try one for my USB bridge in future at least. I guess we should PM each other if we want to discuss more about CPU etc (as this is off topic)
  10. Sorry to hear this. Is this the latest HDPlex 200W ? Did u talk to Larry about it? My latest HDPlex 200W upgrade works fine but I never used the 12V, only 19V and the 2 5 V
  11. We should try to stay focused on the topic of Power supply or at least methods to clean up power, even though the other stuff that we ramble on (including myself) are all very important. Yes (off topic) I also use Euphony/stylus and my CPU is like 2% using 1-3 CPU the most. And somehow the minimal work on CPU create best results, probably as a result of less work needed, and this has been discussed in there original "novel" thread. It was also emphasized before that a great power supply is needed to drive these high power CPU and to only run at low capacity to get best sound. Hence I wonder what would be minimal power needed to run a PC with these powerful CPU, which seems to range from 12-19V. I use 19V/10A HDPLEX 200 but apparently I need this high power to drive the the DC-ATX. Now most LPS are rated about 12-15V and 5-7A for music server. Would a more powerful PS in general be beneficial, too ?
  12. Totally agree, would you say that in general it is better to have a better clock downstream than upstream, assuming somehow you are limited in the clocks you can have (of course best is to have clocks equally good all the way) ? So the downstream clock would not contaminate the audio signal ? I would imagine an inferior clock downstream would be counter productive and would defeat the purpose of an excellent clock upstream.
  13. Now with async USB input does it mean that the DAC is not forcing the clock upstream to clock with it and neither is the upstream clock being the master clock? So the audio signal coming into the DAC from the source would be reclocked in the DAC (usually at the USB-->I2S bridge) , correct ?
  14. Do u mean the local clock ie the clock in DAC? And remote clock is the music streamer or server or CD player etc... ?
