Really? I'm looking for a good one with comparative amplifier measurements.
If you mean speaker amps, I can't help you. The sites I had in mind mainly deal with headphones, headphone amps, and DACs.

Another disputed measurement was the degradation of THD+N in Gen 2 analog board of Schiit Yggdrasil when measuring unbalanced RCA connections. Here is the original measurement in my previous review of Schiit Yggdrasil:



We see that sharp rise in distortion as frequencies get lower.

Here are the measurements I just made but with 90 kHz bandwidth so that the THD+N is correct to 20 kHz:

As we see in the pink measurement, the same problem is absolutely there in the unit I am testing which is the latest with Analog board 2. There is a regression in performance here which Schiit needs to investigate.

BTW, here are Jude's measurements of the same:

I tested two different Schiit Yggdrasils with A2 boards and I get a different results than his. Conclusion?
This review is incredibly insightful. It amazes me how some manufacturers bullshit earnest audio enthusiasts and the general listening public with brand names, big boxes, big sticker prices, and "bullshit baffles brains" fancy websites and marketing talk. It's really a lesson in avoiding making purchase decisions based on proxies for actual sound quality and technical performance.

I get why the review of the Yggdrasil is so contentious; it basically exposes the fact that a lot of people got conned out of a lot of money.

Thanks @amirm for the work you're doing; this is genuinely contributing to people having a better experience when listening to their favorite music or content. I also think that this kind of transparency is great for the audio industry as a whole, as it will force manufacturers to focus on technical performance and innovation.

The owner of the Schiit Yggdrasil DAC had requested that I test the unit after a week of warm-up to see if the outcome changes. I have provided nearly daily snapshots in the thread but here are the summary of changes from day 1 to day 8 with the unit having stayed on the full time. Measurements are with USB input and balanced analog output.

All of these are negligible errors occurring from second to second on their own.

So contrary to what some believe, warm-up makes no difference on this DAC even though it is said to need it.

Please don't waste electricity leaving the unit on. Internet folklore is just that: folklore.

Of course, what is shown to be broken in measurements, is broken regardless of time on. To wit, here are the linearity errors that continue to this day precisely as day 1:

A good DAC will have essentially flat line at 0 dB showing no real measurable error. The Schiit Yggdrasil does not do that: it shows errors which increase as one goes beyond 16 bits of resolution. And passage of time makes zero, let me repeat, zero difference. All the graphs are on top of each other.

If temperature equalization was needed, this could have been implemented in the unit in the form of oven controlled oscillators, temperature controlled subsystems, etc. as is sometimes done in high-precision instruments. The fact that it is not there indicates either the designer didn't think it was needed, or that they took the cheap way out by not including it in such a pricey DAC.

So please don't accept internet chatter on matters that are readily measured. If manufacturer insists on warm-up, break-in, etc., tell them to show you measurements of how they ascertained that. If they say they can't measure it, then look for another DAC vendor.
Once again, more marketing BS from Schiit. It's really disappointing.
