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

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.I suppose so, yes
Why does Raspberry Pi still use mini-B USB rather than USB-C? I dont see the point of A anymore.I think the Zero W is the cheapest board with an easy to use image (piCorePlayer).

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.the usb port being multifunctional may mean noise or distortion.
AbsolutelyUSB has bus power which may not be sufficiently clean.
How about galvanic isolation. Do you deny the effects of this?
Looks like FUDHas anyone tried reclocking?
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.USB has bus power which may not be sufficiently clean.

Utter pointless nonsense.Has anyone tried reclocking?
Has this been cross-checked and refuted with the Ultra?Utter pointless nonsense.
Has what?Has this been cross-checked and refuted with the Ultra?
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"I mean, has an Ultra with a PO100 PRO been measured/heard against a standalone Ultra, as described in YT?
Could the video in YT be refuted?
What's the hope here?
I don't disagree at all,good measuring gear are nice.I measure them all the time,I admit that.Improved measurements, regardless of audibility, is a goal in itself. Lots of us do it. It might be pointless to some of you but... it's our money right? We are collectors of nice measuring gear.
I'm not defending that you tube video which is likely bunk.
The trick is to be honest about what we are actually accomplishing with these better but inaudibly different measurements - arguably nothing. It's a hobby.
That would also be my approach. Perhaps a measurement with DeltaWave could help. I can't say whether the usual subset of measurements is sufficient, and I wouldn't know who could do it.verifying audibility with measurements
Right - but in a world where there is well understood engineering that says there is no benefit from re-clocking, it is still incumbent on the person suggesting there is a benefit.... to demonstrate it.That would also be my approach. Perhaps a measurement with DeltaWave could help. I can't say whether the usual subset of measurements is sufficient, and I wouldn't know who could do it.
For example, I think Benchmark's approach is very good: Link
