You cant understand what I said? Are you becoming canard?
My Ultra tests
- Thread starter onlyoneme
- Start date
Well they are meaningless adjectives. How fat is fat bass? I've no idea. We're back in the world of nonsense YouTube reviews.
You’re the only reader who can’t understand. That’s your problem or go back to school to learn.
Please keep it civil, there's no need to resort to that silly response.
Think about the point I'm making, you cannot use your ears to inform mine without some arbitrary reference. This thread is literally titled Wiim tests, not subjective opinion.
Because you’re asking how fat is fat bass? What’s fat to me maybe extreme to you. Anyway, when topic become objective and subjective it tend to become unhealthy topic as it could set someone on fire of frustration.
I heard synergy all over the place saying if you have bright sounding speaker you should get warm sounding amp to get synergy of neutral sound.
The PEQ shelving function in the ultra can compensate for some of that, making the Ultra as a digital preamp suitable for different amplifiers.
+- 1 dB from 3 kHz can make big differences.
I have tried to have the whole chain of hifi-gear picked by very good measurements, high SINAD and speakers with perfect directivity ( Genelec SAM ) .
Problem was I stopped listening to music because the sound wasnt fun any more, there were no real illusions of real musicians playing together . The music didnt sound musical any more.
So, my conclusion after that sad adventure with ASR star products is this: by combining different gear and listen critical, one can have a much greater sounding hifi and much more enjoyment from the music in the end.

No, youre kind of unique
Vintageflanker said he was to release his measurements of the Ultra last week, but recently he said it would take a couple of more days.
Oh, lolNo, youre kind of unique
As finally another set of measurement has been published - the one from Amir on ASR - some comparisons are possible. While there is a lot of similarities also clearly visible is lack of the noise pollution which I faced. Unfortunately his review misses some tests which could help to investigate the reason of the big difference. I would therefore like to create a list of possible reasons IMO.
1. My mistakes. I consider it rather unlikely because the tests were extended in time and interleaved with tests of other devices. Despite of that the noise pollution was consistent.
2. Single unit failure. I cannot verify it without an access to the another one.
3. HW changes made. I cannot verify it without an access to the late, production unit.
4. Differences in the test gear. AP stuff is much more sophisticated and may handle the situation properly.
5. Cosmos related issue. I will try to discuss it with Ivan on his discord but I consider it also as rather unlikely because I've seen signs of this pollution also when I used my UCX II.
6. EMI/HF noise around which affected results. It would suggest a high sensitivity of the Ultra as I didn't noticed it during tests of other WiiMs.
The list is probably open. Do you have other ideas?

no..but two and 3 to certainly investigate...
(the impact of grounding and its impact on your machine while a class2 was the thing to explain...)
I asked Armim about his pcb and the moment of reception.. probably did not understand the interest of my question, despite what happened on the "plus" and "amp"..
otherwise if vintage is still on the same material terms of cosmos measurements etc..
returns from his machine which must date from the same period as yours could be interesting...

You got better results after a firmware update for the WiiM.
New firmware lowered the jitter according to your own measurements. Maybe thats the only reason for different results ?
Early measurements by you:
After firmware update :

please..
specify “sinad at 1khz”….
important...
it's really becoming a general problem..not just you ;-)
ps..here..it s a 12k (with filter).... for jitter..not value a 1k
impact is not so evident at 1k

filter? earth?
The firmware can shut down parts of the electronics thats not in use if, for instance, using only ethernet to listen to music . You may get better SINAD by, at the same time, shutting down the power for the hdmi input processor. Im not saying that thats the reason for better results , or if they have even done this, but its one way to better the hardware in a product with a firmware update . ( Linn and Naim uses this technique )
Seems to be V2 that Amirm tested, same as onlyoneme.
