bryston 28b sst2 or levinson 532H


I am looking to upgrade my amp from a Musical Fidelity A5cr that I currently have. The speakers are Revel F52. I am wondering if the extra power of the Bryston 28B SST2 (600w) would give me better performance than the Levinson 532H at 300w. Any comments would be helpful as I will not be able to demo both in my system. Thanks.

As a B&W 802D (long known as power hungry) owner who has searched high and low for amps that could make them sing I will tell you it is not just the watts that matter. I owned and demoed many amps with the B&W 802D including the Bryston 14B SST2. I never felt any of the amps were getting the best out of my speakers. Well I have found THE amp. You will hear a lot of nay sayers because it is a Class D but this is based on the new technology of the Hypex Ncore NC1200 that is creating buzz in the industry and the words "game changer" being said. The brand I heard and have on order is the Veritas monos by Merrill Audio .net. Do yourself a big favor and demo them in your system, you will not be sorry.
I own the latest 7Bs (similar to 14B but with more capacitance) mated to F52s and they do a very good job. I often think that the bass should be better but it has more to do with a lousy room set-up. While I have never owned a Levinson amp I would suspect that given that the Revel and Levinson products are from the same "stable" that there would be a synergy between them. I would offer that Levinson could be the optimal choice...
I would go with Levinson out of those 2 just for the simple fact that Revel voices their speakers with Levinson amps.
