Amp upgrade from Bryston 4B

I used an old 4B in my system for several years and was very happy. I then began to upgrade the components around the amp in a leisurely and admittedly unorganized manner. Went from a Rotel processor to a Krell HTS 7.1(Excellent 2 channel bypass). Upgraded my speakers from Klipsch RF7 towers and Klipsch CC amd surrounds, to Hales Transendence 8's and Hales CC and surrounds. Upgraded IC's along the way. Finally needed to upgrade the amp. Researched for a few months. It's hard to demo equipment, so I finally decided on a Spectron Musician, just from reviews and reading the forums. Found one here on Agon used(a Musician ll Hybrid Plus with Bybee upgrade), and could not be happier. The seller through in the Remote Sense cables after the sale(Amazing! Cables and Seller!) The Spectron is light years ahead of the 4B in every way. And the new Mus. lll Mk2 with Bybee upgrade is in your price range. I think they also have a satisfaction type return policy. I use a Parasound 1206 for CC and surrounds. Haven't felt the need to further upgrade yet, but never say never!

I upgraded to a Classe ct 2300, 300 into 8 / 600 into 4, and was surprised how much of an improvement it was over my previous amp, classe ca2200 not subtle. I too plan on upgrading from my current 3.6 to 3.7s. Main improvement in the upper mid and highs less etched more smooth no compression. I also noticed a little more bottom end punch. The amp does not run out of juice and for me makes the 3.6s better or allows them to be better. I think the moral of the story is that Thiels love power. I have seen them used for about 5k

I would upgrade to Class A solid state. Pass Labs, Accuphase, etc. The difference is not subtle.

I'm going to move out of 4B-land (I have the SST model)and into a Class A amp myself. The Bryston is good but not spectacular.
