friggin love this thing
Had the 4 channel version of the SDS-470 for about 3 months now, time to write my impressions. First thing I should say is I've been an audiophile since age 14, and that was 48 years ago! I've had many great amps, can't begin to list them all. A lot of my die-hard audiophile buddies will disagree with me, but I believe class D amplification has come of age, and Tom of Class D has designed one of the best bang for buck amps currently (no pun intended:) available anywhere. This is SOTA at everyman prices - well done Tom.

Specifics about sound you say? OK, well for starters how bout the best mid-bass definition I've ever heard? PRAT is excellent with these amps. Basically what I hear with this amp is a clear as a bell wide band character that does not collapse under difficult "drive" conditions. I do not hear digititis coming from my speakers unless it is in the recording to begin with, and then, yes that also is clear as a bell. This amp does not hide anything, it is transparent to source! High frequency transparency and sound staging are superb, not tubes or solid state sounding, just neutral, natural, and right.

This amp has one other thing going for it that was valuable to me, it is extremely flexible in a multi-channnel or multi-amped system. The level controls on each channel come in very handy in these situations.

Can't recommend this amp highly enough.
