I like 'em.Few tube amps make my 1626 monoblocks jealous, but 2a3 amps at the top of that list.
Unfiltered class D does not sound good, as engineer Bruno Putzney points out in this article on the evolution of class D sound:If you guys want to see what 2-3wpc can actually do on your desktop, just grab 10pcs of the little PAM8403 class D boards for a few dollars. Apart from the residual noise (the PAM 8403 is filterless class D), the power is virtually identical to the baby Schiit unit.
5V supply, run them off an old USB mouse cable and an iPhone charger.

There is probably a limit to what you should expect from an amplifier module that costs $1.22 per 10 pieces lot.Unfiltered class D does not sound good, as engineer Bruno Putzney points out in this article on the evolution of class D sound:

If I understand right I think you might have the right goal here, what is the threshold of audibility regarding objective measurements?When I offered money to any regular at ASR (and the gear to test with) who could identify consistently bad measuring Schiit from good measuring competition, mods removed the posts.
ASR folks refuse to put their ears to the test.
If I understand correctly it's 115 sinads. In a lab setting. I don't think more than 1% of people can hear better than 100 though.If I understand right I think you might have the right goal here, what is the threshold of audibility regarding objective measurements?
Around 115, if I remember correctly. Does that change as we get older, has anybody seen studies on that?If I understand right I think you might have the right goal here, what is the threshold of audibility regarding objective measurements?
Agree. Don't ask for a drop forge when all you need is a tack hammer.It's also worth noting that the ambient noise level of a quiet residential listening space is typically 30dB (or higher), while sustained exposure to SPL above 85dB can damage your hearing. That's a signal to noise ratio of 55dB.
I am NOT saying that's all we should aim for of course - there's headphone listening, peak SPL, times when we want to listen louder than 85dB, and the fact that very low noise and distortion are important aspects of good engineering. I just think it helps to have a little perspective - in normal listening our ability to distinguish between a system with a -80dB noise floor and one with a -95dB noise floor is questionable at best.
