I have a Kinki Studio EX-M1+ class a/b that runs as cool as any class D and will put the amps you listed in the rear view mirror.
Anyone compare LSA Warp 1 to PS Audio S300?
Considering a cooler running summer amp than the VTL ST150 tube amp or Pioneer Series 20 M22 full class A amp. The LSA and PS Audio are similarly priced at the moment. Both are class D. I've never tried a class D. Have numerous speakers from 4 to 15 ohm.
Thanks,
