Choosing the right Bryston amp

My friend is a bit shy. In response to this topic, he wrote:

"The 4B-ST really makes my F-30's sing. I think that they absolutely need the 4B's power to perform at their best. I am getting full range, nuanced performance from my setup. Of course it helps that I am running excellent front end gear, the ARC LS-3 pre amp & Naim CDX, as well as excellent Kimber Monocle-XL and Transparent Reference interconnects. If I went anywhere, it would be more towards more power and dynamics, probably to monoblocks."

I would only add that his listening room is roughly 13 x 20 x 8, and that my Revel Salons, which are admittedly a different speaker, did like power.

why bryston ?? why not consider an amp with ice power ?

Thanks for the replies.

I'm soon going to be auditioning the Van Alstine 350EXR Ultra (a tube-MOSFET hybrid amp). It has more power than my 3B (rated 160wpc, but Frank Van Alstine told me it's really closer to 200) and is supposed to sound, you know, better and stuff. (It uses tubes to handle voltage and MOSFETs to drive current. Or some such thing.) We will see. Many thanks for all the different recommendations, especially Raquel for tracking down your friend. The observation that the Revels like power is duly noted. Frank told me if the 350 isn't enough I can upgrade to the 550 (250wpc) for the price difference of the two. But I will definitely be keeping the higher powered Brystons in the back of my head, as I like the amps' neutrality and resolution pretty well.

So anybody please feel free to discuss and opine on these Van Alstine products, as I know they are somewhat out of the mainstream (not being sold by audio dealers). They're pretty inexpensive and seem to have the reputation of outperforming far more expensive stuff. Anyway I'm looking forward to trying it out.
