Rather than this spectral debate, I'd ask for a simple display add-on, an immediate switch to make Ultra to work as a "pure transport", bit-perfect mode via USB or Optical.

Better if exportable to all Wiim devices.

So this would immediately bypass all EQ, and RoomFit settings, that sounds good to me, but it would also need to apply to Coaxial Output.

switch to make Ultra to work as a "pure transport", bit-perfect mode

This was requested, and discussed, many, many, many months ago.
Back in the good old days there were literally just a few options to revert to bit perfect. You could even just enable the MQA beta toggle for it
Now there are a zillion options. Some call it progress

iirc, Wiim commented that it could / would be implemented. Don't think they said when...

I received the update yesterday evening (CET)
I am enjoying the addition of the spectrum analyzer.
Another fine update by WiiM

It would be great if I could put a USB pendrive on it and select it from the touch screen. It would be nice to solve this somehow By the way, is there a difference in sound quality between firmwares?

By the way, is there a difference in sound quality between firmwares?

In general no unless WiiM have expressly said so, or unless a bug crept in…

What firmware updates are coming soon, "via trickle-down," to products other than the Ultra?
The "lower-end" models? No screen etc...
Will these updates affect streaming functions, or are they purely audio-related?
Thank you
