Or is your judgement based on listening?Powering your pc with a LPS isn't good enough. Big sonic gains can be had by powering your hdds and usb ports separately and by using good usb cables of SHORT lengths.
Comapred to the Wyrd, the Regen makes a much better difference, whatever Schiit says. Actually they power the Wyrd with a 30 year old 723 IC (which has broken down in my unit) and this supports my point about power supplies.
I am listening to Livingston Taylor hires right now. His voice is not FAT. It is clearer and the whole reproduction has the merits of what I said in the thread.

I agree, Fred, just powering your PC with LPS or battery instead of supplied power brick or SMPS PSU isn't sufficient for realising high quality SQ from computer audio. There seems to be so much ground noise pollution on motherboards which ultimately finds it's way to USB connected audio devices via ground &/or signal wires that the only way to address this is to isolate & power individual sections of the PC. What this seems to do is to localise the ground noise to that section & prevent it from polluting the rest of the motherboard?
As you have done, treating the big sources of such current noise first is critical - anything which has large pulsed current draws is a candidate for this treatment - any electromechanical devices such as HDDs. Interestingly, memory is also a good candidate for such treatment as is USB ports.
You will find much more detail on that forum I suggested.
Even LPS powered Regens sound different depending on the LPS. The usual Teradak 9V doesn't sound that great either.
Superdad didn't like it when I said in response to his posts about 'expensive' TPS regulators being 'best' that there are actually better regulators that won't break the bank, but he tried to divert the subject of discussion. I therefore would guess that your experience of direct regulation being better to be true..
Nevertheless, the Regen des remove the last bits of hf distortion in hirez replay and is worthwhile. I get better SQ from a 10 cm Wireworld Starlight Silver than from the 'solid' connector which is not solid in terms of construction. Using it, I can hear some hf anomaly.
Sure - don't get me wrong - I'm not saying that the Regen, powered by LPS or even SMPS, doesn't improve matters somewhat, for most - it's just that feeding with LiFePO4 battery directly is a very noticeable improvement.
