FEZZ audio

If the channels can be paralleled, that would give 90W per side, which is overkill for your 92db speakers. But of course that depends upon what the efficiency curve of your speakers really looks like, and more power never hurts. (The 92db rating of your speakers may not apply at bass frequencies, for example.) The 45W per channel of one amplifier should be fine, assuming the 92db rating is legit. The only question I would have is whether these amplifiers are "special" in any particular way, in terms of sound quality. You’ve got a single 12AX7 per channel driving a pair of KT88s per channel and possibly a toroidal output transformer (just a guess based on the cylindrical cans), unless, for example, there is a solid state driver stage in between the 12AX7 and the KT88s. Otherwise I wonder whether the 12AX7 has enough oomph to do the job well. The amplifier is certainly attractive from the outside. If you have heard them at the store, that’s a good thing. Maybe you can borrow a pair from that dealer and try them out on your own speakers.

I know Jeremy @ Aural Hifi - good guy.  I also know 3 other reputable dealers, 2 in Northern virginia, one in north carolina, who carry the brand and think very highly of it.  

Thanks all for your in put. Fezz won the Red Dot award in 2023.....not sure what that is.  Is it reputable or BS?

Mdalton., my wife and I were very impressed with Jeremy.  Could have stayed all day and I think he would have let us.  He had a pair of DeVore O96 speakers going and Holly crap!!   Wow!! We had just come from The Music Room where we heard a pair of Sonus Faber. I think they were Il Cremonese. They were hooked up to McIntosh mono  mono blocks and all of the good stuff. They were good but I wasn't wowed.  Made me feel pretty good about my system.  But the Devore's....next level. 

@OP Red Dot is an industrial design award. It has nothing to do with sound quality.

Like I said, the dealer may be Mother Theresa, but if Fezz is driving a pair of KT88s with a single 12AX7, that makes me wonder about how it might sound. Normally you would want to have a separate driver stage if the input tube is a 12AX7, because 12AX7 does not swing much current to drive two such power tubes.  There may be an invisible SS driver stage, which would render my comment moot.  Anyway, the proof of the pudding would be to borrow an amplifier for home audition, if possible.  On the subject of power, I neglected to take into account the nominal impedance of your particular speakers.  If it's less than 8 ohms, that might suggest Mijo was right to suggest using two of these 45W amplifiers strapped for mono, if indeed they can be strapped for mono, but that gets VERY expensive.
