My Ultra tests

[canard]

The old readings were below human audibility, so it hasn’t become more transparent.

Have you read, explored the relevance, the limits, the population concerned, etc ,of these studies to which you refer?

Which ones did you read?

hihi... that's really not an answer...

A peer reviewed paper including properly, independently conducted testing isn’t an answer?

You didn't link to one paper but the entire AES library. I think, that's where the questions did arise.

 

[Steve Woodhouse]

WOOPS! I’m on my mobile, and now in the pub.

I’ll update later.

Many apologies to all.

 

[onlyoneme]

Few words about the jitter added.

Very interesting test with Spring 3. Looking forward to comparison with other WiiMs you mentioned earlier!

Yeah, I'm working on that.

 

[onlyoneme]

I can say for now that the Mini's toslink output is much worse.

What is "Spring 3"?

 

[onlyoneme]

Holo Audio Spring 3 DAC.

 

[Steve Woodhouse]

My apologies for not being able to post again more quickly. The worst the jitter is in any of the graphs is here:



The biggest peak there shows causing distortion at -121dB. All the others are -139dB or lower.

In both cases, that’s totally inaudible.

 

[onlyoneme]

I won't even comment it as you do not understand the difference between the jitter inducted spikes and the harmonic distortions.

Jitter over digital outputs for different WiiMs

Let's talk about the jitter over digital outputs. I will use the Holo Audio Spring 3 DAC which is a true NOS DAC and has an unique ability to turn off its PLL. This way I can compare a raw performance of the outputs in j-test. Ultra, toslink: Ultra, coaxial: Pro, toslink: Pro...

At a moment I assume that both Pro and Pro Plus have similar results, based on the oscilloscope graph, but I will verify it later.

No, not at all.

But below 120dB you can’t hear it.

I would like to see next level of measurement of sinad of 140.

I don’t there’s anything wrong with pushing for better and better measurements. There’s pride in ownership.

But for me, I don’t have that ‘hobby’. I just want my system to sound as good as possible.

There are many reviewers out there but one I like reading was audioholic based on science with explanations for those don’t understand. Gene from audioholic.
