Hi. I'm relatively new here, but not to audio. I think you might want to consider the possibility that your components just don't like each other. I have heard several B&W loudspeakers at various dealerships. And I can tell you from experience that I found B&W's really came alive with the right amplification. Bryston make great amplifiers, and they are known for quality and reliability in the professional studio market as well as the mid-fi and hi-fi markets. But keep in mind that they are also very revealing amplifiers, which means they can bring out the worst in your recordings as much as the best. I did some experimentation about a year ago with B&W 801s, and I found that to my ear, among Krell, Bryston, McIntosh and Classe, I liked the Classe monoblocks I heard best with the B&Ws.
It is all about synergy with audio. Not every speaker will sound good with every great amplifier out there. If you are interested, we can help you out at Ciamara, but I will leave it at that, as I do not want to advertise our business in the wrong area. Either way, consider that your amplifiers may just not be the best for your speakers, or your personal tastes for that matter. If you want a more dynamic, full and moving listening experience, a few slight changes may be all you need. Good luck, and hope to hear how you get on.
