WiiM Amp Ultra Users Experience

Another point that plays a role is the damping factor.

WiiM Amp Ultra has a high damping factor (i.e. low output inpedance) and is therefore for all practical intents and purposes load-independent.
This is visible in Erin's measurements as well as my own (we both measured with complex loads too).

It's of course fine if you don't like the device, but damping factor is definitely not an issue.

The value of the Damping factor is critical in any case, which is why manufacturers list it. As for the value of 94, it reminds me of amplifiers from several decades ago, and this explains its sonic behavior. I didn't write anywhere that I didn't like it, on the contrary, I wrote that it sounds good with voice and a few instruments.

You are right, competent audio amplifiers existed decades ago as well.

The difference in response deviation between damping factor of 94 and e.g. 300 will be in the order of about 0.1dB.
This is very unlikely to be audible or meaningful - especially when you also consider that speakers often deviate >3dB in a single axis response, and rooms often introduce deviations on the order of 10dB+. Actually, just moving your head a several cm will change the response by more than 0.1dB...

I didn't write anywhere that I didn't like it, on the contrary, I wrote that it sounds good with voice and a few ininstruments.

Sorry for my misunderstanding!

Yes i know it .You want to write Wiim Ultra Amp ? Ok
Sorry ,i m talking about Wiim Ultra Amp
It ,s O.k ?

There's a product called WiiM Amp Ultra and there's a different product called WiiM Ultra. Yes, it's very much appreciated if you use the actual product name instead of another product's name.

As pointed out before, the product called WiiM Amp Ultra sells for <600 EUR, so it remains unclear why you mentioned a selling price of 800 EUR in one of your previous posts.

The value of the Damping factor is critical in any case, ...

In any case? Why do you think so? The damping factor is nothing but the output resistance of the amplifier relative to an 8 ohm load. There's no "magic" to it.

... which is why manufacturers list it.

Many actually don't. And if they do, it's pretty much pointless unless they specify the damping factor (or output resistance) over frequency.

As for the value of 94, it reminds me of amplifiers from several decades ago, and this explains its sonic behavior.

What do you believe is explained by this value?

Five decades ago, a fellow called Floyd E. Toole published an article about why damping factors >20 don't provide any meaningful benefit in AudioScene Canada. You might have heard of him later on.

Unfortunately, I notice that some commentators remind me of the corresponding commentators on the RME forum, where they consider the RME ADI 2 PRO DAC to be one of the best in the world, regardless of price. It seems that the same is happening here with some. Of course, not even the excellent engineers at Wiim believe such a thing.

We’re fans of the brand and its products for a reason, and that’s why we’re here. I don’t see anybody claiming it’s the best thing ever, but for many of us it IS the best choice for our needs and budget. I know that I chose WiiM after sorting through many other options, because it does exactly what I need it to at a very reasonable cost, it is very user-friendly, and there’s this extremely knowledgeable and helpful user community sharing info that I never knew I never knew. And yes, cost is a big consideration - not everyone has tens of thousands of dollars to dump on sound systems. I am completely satisfied - overjoyed, actually - with how it’s all working for me, it sounds fantastic, and there is nothing out there right now that I would replace it with. I can’t speak for everyone else, but I’m pretty sure a lot of other members here are similarly pleased. Sorry if that’s a problem for you.
