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


Do you have Spatial Audio speakers in your system? Do you use solid state or tube amps to drive them, and if so what models sound best?

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.
