Please do - I don't have an account or a Wiim. It's tempting, but piCorePlayer and similar already do what I need for streaming, and the Ultra doesn't have enough inputs yet to be a full preamp replacement.

Fully agreed.
I'll place it as soon as possible.
*EDIT* just done, let's eagerly wait

Are you including things like a Pi Zero W?
I suppose so, yes

I think the Zero W is the cheapest board with an easy to use image (piCorePlayer). There are cheaper boards, but you would have to roll your own software. piCorePlayer needs LMS (Lyrion Music Server, formerly Logitech Media Server) running somewhere on your network, and I don't think the Zero can run it, so you might need a step up to a Zero 2W. That might open it up to other Pi streamer images too. Then there's a case, PSU and uSD card, and probably a USB mini-B to A socket adapter. If you don't have them already that adds to the cost.
Why does Raspberry Pi still use mini-B USB rather than USB-C? I dont see the point of A anymore.
Why? You can't get more multi functional than ethernet & TCP/IP. It carries all the data for all the applications in the world - yet it can still transport music perfectly.
And distortion of what?
If the bits get distorted - they still either work or not. The music is either as intended, or grossly disturbed (Pops, clicks, dropouts or complete loss)
Sure - just as with any other electrical interface, digital or analogue, you can get ground noise. But that has nothing to do with USB being multifunctional. In fact it has nothing to do with it being USB.

Looks like FUD
Sure - galvanic isolation breaks a ground loop (if there is one, and it is causing audible issues). You know: the ground loops I mentioned in my post? But, again, is nothing to do with USB being multifunctional, and, incidentally, rarely to do with USB power being insufficiently clean. Nearly all (or all) instances of people describing "noisy USB power" are actually experiencing ground loop noise.
Utter pointless nonsense.

Has this been cross-checked and refuted with the Ultra?
Has what?
It doesn't need to be. The Ultra already measures as audibly transparent (flat FR, & inaudble noise and distortion). Even if the re-clccker makes a measurable improvement - which is itself unlikely - it can't make the distortion "even more inaudible"
Re-clocking is about jitter - but jitter has been a solved problem for decades now and doesn't need to be improved. The only reason for re-clocking today is where you have multiple devices that need to be synchronised : typically only a studio application.
And fundamentally - you are asking the wrong question. When someone starts promoting this sort of nonsense they are the ones that should be verifying audibility with measurements. You should not be asking someone else to disprove all the nonsense that can be fabricated by anyone anywhere.
Instead of asking if it has been verified that this doesn't work, ask cheapaudioman where his measurements are. If he can't provide any, then you can reasonably discount what he is saying.
