So here's what I'm thinking......now that I have my Sonus Faber Stradivaris (Strads) back in place (should NEVER have sold them in the first place), I have been trying different amp combinations. The Hegel H30 is terrific and the stereo version is a keeper, the Cary 805AE's are the unanimous choice by visitors. With all the upgrades done by Cary combined with the 1940 GE 211's, WE300b's and MELZ 1578's, this 50 watt SET is a world beater. But I can't leave it on and forget it during the day for occasional listening. The Pass XA60.5's are wonderful - I think I want more of that!

But the heat from the big boys! The Mc275's and VAC phi200's are good, but are going to be sold.
The good news is that no matter what amp I put on the Strads, they offer varying degrees of good. NOTHING sounds "bad". I LOVE these speakers! Did I mention that? No bass issues!! :woot:
Given this, I want to find a world class amp/preamp combo now that will work well with the Strads. I'm looking at Pass XS150/XS Preamp, Allnic A-6000/L-5000, Accuphase A-200/3800 or back to the tried and true Mc2301/ARC REF10 combo.
Concerns:
Pass - the HEAT!
Allnic - the TUBES!
Accuphase - $20,000 in Japan, $70,000 in America. Really?
Mc2301/REF10 - owned them before. The 2301's can be sluggish. Will some 6550 tubes change that?
I've ruled out Soulution (despite it being a great SS amp, just don't see it as a good match), Constellation (just not a fan), Spectral (don't want to have to buy MIT cables, don't see it as a fit), Boulder (pricing has reached new levels of insanity), Audio Note UK (just not seeing a good fit), etc.
Thoughts?
