I don't have any Emo amps, but I do have a pre-amp and DAC.
These are definitely well built electronics. The aesthetics and the chassis are nothing to write home about, likely save a few bucks there, but I'm good with non-flashy gear.'
They are not statement pieces, so they won't have that level of build quality, but the separates are better built and better components than any commodity AVR on the market.
Now, if it matters to you (and it's a moot point for a power amp), the remote controls for the Emo are extremely well built and much nicer than you would expect at these price points.
