Spatial Audio speakers sound best with Solid state or tube amps. If so, which models?

TTW Turntable with copper platter, Arvo tonearm, Ortofon Cardenza Bronze Phono Cartridge and Triode of Japan CD Player. PS Audio Premier Power Plant and Acoustic Zen Cables. I also have A NAD S 100 Amp but prefer The Tubes

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.

Mine replaced Maggie 1.7 with DMW Sub

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.
