I have the M4 Turbos powered by a Class D Audio SDS-250. Sounds good. Most of my listening is done using a Squeezebox Touch and Schiit Mimby. The M4's were a nice step up from Maggie MMG's.
fr8dog, was the Class D Audio SDS-250 the only model available when you bought? Just wondering why you didn't get the SDS-500? And, did you buy a kit or a complete amp with case?
I had been interested in the 470 because my speakers (MMG's) went down to 4 ohms. A used 250 became available (also 4 ohm) so I jumped on it. The amp was complete. Does what I need it to do. Drives my speakers and doesn't turn my room into sauna.
