I was in the same boat and got this one:

Sounds very good!

I need more amps though to go with my miniDSP nanodigi so I'm tempted to try out one of the newer digital-only amps (to save on DACs) that give about 60-80W in 8 ohm:

Or get fully assembled versions at Classdaudio.com. That would be my recommendation. I see the CDA megathread is still going 6 years later (!)

Edit: I see Matt has already mentioned it!

A couple of friends have CDA amps.  Take my impressions (listening through their systems) with a grain of salt.

Compared to a Crown 1500 (how is it nobody has mentioned that one?) on the same system it was more detailed/dynamic/forward but a bit rough to my ears.

I have old Channel Island Audio D-100 mono-blocks that IMO beats both of them, but the new versions are much more expensive (I'm sure they sound even better).

In regards to the cheap ebay irs2092 boards: pretty sure I've read a few comments on diyAudio about them having atypical input impedance (i.e. may not mate well with some sources).  That's all hearsay and foggy memory, so I'll see your grain of salt and raise you five.  :)

And with Class D Audio, the difference between their CDA (cheap) line and SDS (more expensive) line is that the latter has an input buffer, which should make them much more forgiving of the source device.
