Tube amps under 1,800 for gallo 3.1's

You can bypass the pre-amp section of the bel canto and drive it with a tube pre-amp; I did and I think is added some of the elements you're seeking. Many options to consider, but I use a Rogue 99 (NOS tubes) which probably falls on the lusher side of things.

The bc with 99 were not quite as good as the 99 and Rogue 90 amp but it was really very close.

Steidlguitars..I already sold the bel canto.

maybe a hybrid amp would work for you like monarchy audio
SE160 mono's.

bump for more opinions.

This is the 4th thread you have started asking about amps for these speakers. How much more input do you need? Buy a SS or class D amp and a good tube preamp which is what almost everyone has already suggested. Tube amps are not going to get you where you want to be with these speakers for rock and roll.

You can get a new Wyred 4 Sound ST500 from Underwood hifi for 1,500.00 or another Bel Canto, or Belles, PS AUdio, an older Krell, Classe, or Pass Labs will probably all be a good match.

There are a bunch of great preamps from Manley,VTL,Rogue, Modwright,Cary,Audible Illusions, Audio Research.... All from just under $1,000 to $2,000 Wyred 4 Sound even has a new preamp out to match their amps for $1,795.

Except for the couple of brand new items in my list if you don't like the piece you can resell for pretty much what you paid for it and try something else.
