@avanti1960 thanks for the reminder about Pass - that should definitely be on the list.
@lalitk Warm for sure. My guess is I should not be concerned about lower wpc specs of the Accuphase?
@stuartbmw3 @akg_ca I had (still have) 30.2's with 2 REL subs. I appreciate the feedback but the 40's are a completely different animal compared to any of the smaller Harbeth's.
System details are in my profile, but my current amp is Rogers High Fidelity EHF-200 MK2. This amp drives the big Harbeth's really well, and actually sounds much better with the 40's than the 30's, and inexplicably seems to drive the 40's with less effort.
I have zero complaints with the current set up, I'm just interested in trying SS. (I have never owned a high-end SS amp).
Thanks for all the feedback thus far.
