Amp upgrade from Bryston 4B

I currently have Thiel 3.6s main speakers driven by an older Bryston 4B amp that has been a good match. I have been considering upgrading the Bryston 4B amp to used Bryston 7B mono blocks(?) However, the Bryston 7B amps have had mixed on-line reviews. Any other recommended amp upgrade recommendations in the $5K used range that would be a good match for the current Thiel 3.6 speakers and potential future Thiel 3.7 speaker upgrades?

OTHER EQUIPMENT: I am setting up a 5.1 surround system with an existing Rotel 985 5 ch amp to drive Thiel SCS4 center and Higherplane 1.2 rear surround speakers. I am currently using an Outlaw Audio 995 processor in bypass mode for 2.1 stereo listening.

I would tend to agree with Soix that a pre amp processor might be a better place to look for upgrading. However, if you are still on the hunt for a better amp. Have a look at this Llano A-200 that's on Audiogon.

Hi Hasse,

As a matter of fact I have, not side by side though.

Anyway, the Pass Labs Class A amps are arguably better built, are more musical, and are more dynamic. I believe they can drive lower impedances better too.

If you have a Pass Labs dealer in your area, have a listen and see.

If you like the sonic characteristics of the 4B, the 14B SST Squared is magical in its combination of power and staging, detail and depth. I have heard them both sound quite excellent with THIEL.

Thanks Dave

Unfortunately I do not have a dealer locally for auditioning. I am interested in either the 7/14B SST2 or the XA100.5 for my Magnepan 3.7´s.

Can you get to one out of your area? Pass Labs is a nice friendly company that'll steer you in the right direction if need be.

Imo, the XA100.5 will blow away the 7/14B SST2.
