classe ca-300 or bryston 4b sst for thiel 2.4


i am currently running my thiel 2.4 with a classe ca-300 amp, but i am not 100% happy. i am getting a 4bsst for a bargain price. which amp is a better match with thiel??
my other equipment is sonic frontiers line 1 preamp, classe cdp cd player and acoustic zen cables.
i am looking for more bass and not to bright highs.
thanks in advance

I have owned both the CA-300 and Bryston 4bsst. If you want more bass and less "bright" highs- look at different amps than these two altogether. But, I would first try driving the CA-300 with a different pre-amp than the SF.
I agree with the above post. Try a different tube preamp. That can make a large difference. Going to the Bryston is a waste of time imo.
I agree with with the observations of fellow A'goners. Keep the Classe amp and try another pre. It seems that you would be making a 'lateral' move with the Bryston. I might recommend a BAT pre., nice and warm and no harshness or brightness. Just my 2 cents...
i had a 4bsst that i sold to lower my investment in gear due to other priorities. replaced with B&K monoblocks - the 4bsst was definitely warmer and low end extenstion for day. driving a pair of Boston Lynnfield 500L's this is the best amp i had used to date. (ive had proceed, aragon, adcom, ayre and legacy...) the ayre would be the choice if it had more power - imo.
plenty of power to satisfy these inefficient speakers. i have never audiotioned a Classe in my system although i have heard good things about them. if you can save $1000 or so on the bryston i would think that is the way to go. not the absolute last word in resolution however. i heard esl makes an amp that has huge current and great sonics - maybe worth a try?
Well I might help you as it seems we have the same problem. I currently have 2.3 with MAC C2200 tube pre to MA252 SS power amp. I think overall sound is a little to vailed and bass does not kick the way it should. I demoed 4Bsst and found bass to be great. What I also liked was low SPL bass presence I do not get with MAC power amp. I certainly wouldn't call Bryston in my set-up bright. Highs are more present compared to MAC (and I like that). Mids are not so great as thru MAC though. Sound is with no question leaner and dryier thru Bryston. But still I think I would do better getting Bryston.
Mac sounds very good when played very loud. Most of the time I listen low SPL and then I like bryston more.
