Class D with high efficiency speakers

I would not sell the OTL - wait until you’ve tried other types of amps, and give it time. I have Atma-sphere MA-1 v 3.2 monoblocs, mainly fed by the Io Eclipse. They are a daily joy in our system, with top level NOS driver and output tubes and clean power. I am on regular visits to my friends in our local audio circle, some of them with class D amps, but I always come back thinking that I love the tube OTL sound at home.

I was surprised that Ralph / Atma-sphere - post above - wrote that he didn’t miss it (M-60). I am sure his new class D sounds good. But I would guess it is a case of plus and minus?

I am sure class D can sound great and it would be great to try, with my sensitive Dream Maker speakers (16 ohms, efficiency:  92 dB/1 watt, Voltage sensitivity:  89 dB/2.83 volts). If class D can lift these even further I am all ears.

I want to correct an impression I may have given in my post above. I have not heard many class D amps in my audio  circle. Mostly, solid-state amps at a lower price level than my MA-1s. So - I really don't know.

One  thing I do know, is that running the passive speaker in an active speaker combo from an MA-1 amp instead of the active speaker amp, can result in a big lift of performance. This includes Audioengine and Elac active speakers. They sound much better.

Atmasphere - thanks for an informative answer, as always. I am not sure about the Dream Maker speakers, but it may be that they are designed for high output impedance from the amps (like your speakers) so that class D might sound a bit lean, compared to more beefy OTL sound from the MA-1s. Not sure, have never compared. My gut feeling would be to try class D first in a smaller system.
