No, I'm just simply stating a fact that there are opinions on both/all sides of a debate, and it's not offensive or rude in any way! People have the right to decide there own verdict based upon the cases "for & against" (i.e. the prosecution & the defence) the argument. If people want to add comments to this thread, they are quite welcome to do so in my opinion and I will read from a neutral point of view. Be that pico, or no pico. Thanks for asking! B.T.W. Tomslin, you have given me a lot of help, cheers! Yes, of course, I agree with yours statement here. But I start to believe my help is more useful in this (yours) debate here than it's helpful in your own decision (ie pico or not). However, I wish you good luck! Thanks for me. the_doc735 1 Link to comment

I mean, if your “debate” here really are about the best possible power supply for a computer, ie for best possible audio reproduction. And this article has nothing to do with that. It's even written on page 1 under introduction: "The popularity of mini-ITX continues to grow as people build media centers and in car entertainment systems that don't require as much power as a standard, full sized ATX computer needs, and doesn't have the room to accommodate a full sized ATX power supply". But I guess you just saw many fine ripple values, which seems to interest you the most, though it in the reality are quite uninteresting. If you are really interested in creating a really good computer system for the best possible audio reproduction, I recommend that you read this. It’s very well written and focuses on what really is important. https://www.pursuitperfectsystem.com/building-the-ultimate-music-server---hardware.html the_doc735 and Marcin_gps 1 1 Link to comment

Asus PZ87 [Micro] ATX Mobo Intel Core i7 2700k CPU (TDP 95W!) NB: Lower power in the CPU will mean less noise from the switching regulators on the motherboard and therefore better sound, but by all accounts i7 CPU’s sound better. 8GB ECC Industrial Grade Ram Small capacity SATA SSD (for O/S, Audio apps.) Separate storage for audio files. NB: You could choose SSD, M2.SSD, (NVMe), USB Stick or a mechanical hard drive. When it comes to sound quality there are a few hard and fast rules you should adhere to. Specialist O/S SSD by PPA w/OCXO (uses lots of power & slow). You need to copy a clone version of an o/s installation onto this device. JCAT SATA cable(s) JCAT USB Card FEMTO w/JCAT 200W Linear Power Supply JCAT NET Card FEMTO w/JCAT 200W Linear Power Supply JCAT Reference USB Cable JCAT USB Isolator & USB-ISO Cable 3M AB5100s chassis RFI/EMI absorber JCAT M12 SWITCH GOLD [for networking] Note: A far better approach will be to use a Pico PSU w/LPSU. Using a good Linear Power Supply with pico will sound far better than the usual pc SMPS. This is not a small difference it’s a night and day difference and it’s actually the first thing I tried for achieving better sound from a dedicated pc source. ******************************************************************************* MY HTPC: MSI Z370i GAMING PRO CARBON AC mini-ITX + Intel® HD Integrated Graphics 630.

I am told on this forum (C.A.) that I don’t need OCXO for this PC because the master clock is in the DAC, in my setup, and that the Crystek 575 in my DAC is already a very high quality clock which would require ‘a ton of money’ for any significant improvement. Moreover, there are apparently ‘buffers’ between the clocks that negate any errors. So, this means that fitting an OCXO to the PF i2s PCIe card would be pretty pointless as it’s not the master clock in the chain and I am not aware of anyone who has successfully fitted OCXO clocks to a commercial mobo, even paul pang withdrew his product due to incompatibility issues. I have not used any 3M AB5100s chassis RFI/EMI absorber, or similar. Music storage is external. Currently using USB v3 memory stick.

billg Posted August 26, 2018 Share Posted August 26, 2018 I use a dedicated network file server. It's windows 2016 on ssd, Audiophile Optimizer, music files on internal HDD with a SoTM noise filter, minimserver. I definitely prefer it to the qnap nas I previously used. Of course you can trick this out forever with linear power supplies, network cards, cables, etc. See this Jplay thread for more details. the_doc735 1 Link to comment

What technical evidence do you have to back up your preference? OR: is it a preference 'BY EAR ONLY'? ....did you do a blind test (i.e. before/after)? Sounds like: "a sledge hammer to crack a nut" solution to me! All that gear! More complications, more issues, more hardware, more software, more noise/ripple, requiring more (SoTM ) filters to clean it all back up again? "Miniserver", surely that amounts to no more than a second mini PC? Why? And! ~ if it's wireless (WLAN), then there is more airborn noise pollution to deal with as well, e.g. local radio waves from everywhere/anywhere getting into your music! i.e. network file server + windows 2016 on ssd + Audiophile Optimizer + SoTM noise filter + minimserver! "OTT"? How about: eSATA SDD? (wired). Link to comment
