Just how much are you looking to throw at an SS amp, BTW?
Mono blocks? Stereo?
I'd think a natural mate would be the Cary 501s.
Does that pre go out xlr and rca?
on a budget, you could do worse than an odyssey Extreme, or for less, the Stratos Plus.
For the $$, and with your pre, I think you'll be suprised!
A BAT vk500 would be nice after that... BAT pack preffered of course.
Pass too might give you as much bass.
those 402 Mcintosh' amps sound pretty good and keep their value... but they're pretty hefty.
for that matter the Krell FPB 200 has great botom end and is very neutral. your preamp will definitely have an influence.
I enjoy your musical tastes, and would mention the Dodd MK II or even the ones out now, depending on how much is in the till for this adventure... with the cap upgrade, blues, R&B, complicated jazz, etc, should sound great! BTW, the 120 wpc MK II do seem to have a bit more on tap than does the Odyssey Stratos Plus at reportedly 180wpc...; or it sure seems that way.... it isn't 4 to 1 though.
if you want to stradle the fence some, try auditioning the Butler 2250. outstanding imaging and quite natural sounding. Plenty of that PRAT business too. Very nice IMO.
