we don't know...@canard Normally a rock has its most solid part at the bottom, the rock would not even notice it. And thats what happens, I am sure.
Count me in on this... the GUI still looks very gimmicky and a little cheap. I thought WiiM once teased they would implement custom themes or something. @WiiM TeamI agree with amirm's "overhaul of the GUI with a better platform".
Amir always updates the firmware as the first step of a review. So you can guesstimate by the date of the review. Probably the 9/27/24.
He didn't manage to find the DAC output filter selection, though, which left me puzzled.
Yeah, I can finally sleep at night tooI could not be happier
He didnt check that there were volume numbers in the display, he didnt check the digital outputs ( USB out ) , he didnt check or mention the ability to use the USB input to drive 2T SSD discs . He didnt check the digital volumecontrol .
Why would the use of an Apple remote, external storage or the use of a USB DAC have to be part of his tests? They don't have anything to do with the internal DAC & ADC performance. (test) files loaded of an external drive will sound just the same when played over network and with digital audio output over USB, the performance depends mainly on the external DAC.
The tested versions by onlyoneme and Amirm seems to be V.2, printed inside of the Ultra. Are there any V3 out there ?
Symbols printed on PCBs seem to be uncorrelated with the PCB ver returned by the API, as it could be seen so far with the Pro Plus or the Amp.
Do we have any evidence that released units have been anything other than v2?

Ultra's dac sounds like crap compared to my RME (which is also transparent). Just saying...Its coming more ….
This review show two things :
1. The SINAD is 115 dB and theres no powersupply issues .
2. The default digital filter is very good = the sound will be transparent to the source .
3. To get better perceived sound than transparent you will need a colored dac.
4. There is no ESS hump to talk about.
Overall, the measurements are what to expect using this dac and opa1611 in four places
I could suggest that you have a read of the 511(!) pages on ASR that discuss the sound signature of transparent DACs, but I wouldn’t inflict that on my worse enemyUltra's dac sounds like crap compared to my RME (which is also transparent). Just saying...

Now that comes as a surprise...I could suggest that you have a read of the 511(!) pages on ASR that discuss the sound signature of transparent DACs, but I wouldn’t inflict that on my worse enemy
Edit: for the masochists amongst you, here’s the link. I haven’t read it all but I doubt it’s 511pp of agreement that all transparent DACs sound the same…
Serious Question: How can DAC's have a SOUND SIGNATURE if they measure as transparent? Are that many confused?
Food for thoughts... This is 1kHz @-6dBFS from an old Marantz CD4000: And this is the same 1kHz @-6dBFS from an AH! Njoe Tjoeb 4000 CD player which is a clone of the Marantz with a tube output stage: Tubes might need some attention (it will be done soon). Now, fun fact, recording from...
