Holy Grail of D Class Amp

[adifferentpaul]

Welcome!
There are some good threads on this forum comparing the M700 to M1200.
I haven’t seen any threads regarding the Legacy Audio IV amps.

PS Audio M700 vs M1200

I haven’t seen much about a direct comparison between these two amps. Most of what I’ve seen compares these to the BHK250. Anyone have direct experience with the M700 and M1200? What differences can I expect from the tube integration in the M1200? I don’t really care about more power as I use very efficient speakers (normally Klipschorns and Tekton monsters).
