After running my Aerial 10T's with a Bryston 4BST for 6 years, I just upgraded to a 14BSST. In a 14X23 room, playing at moderate lev els, the difference is astonishing. It is as if the speakers had been half-awake. Not just the bass, but the entire range seems more coherent, energetic and alive.
I am posting this because there is no longer either a Bryston or Aerial dealer in my city. In general, I find the knowledge of even specialty retailers to be limited. Therefore, I have had to rely on the forums for information. The controversy about the value of increased amplifer power is such that I struggled for months to make the decision. My wife and I are both thrilled.
At the same time, I used the 4BST to replace a 9BST that I was using for just the side surrounds (Aerial SR3) in a separate surround system. Again, on these small speakers the difference is astonishing. The surround system also includes all Aerials: 10Ts, CC5, LR3 and the above-mentioned SR3, and a SW12. Other Bryston amplifiers in this system are the 6BSST and another 4BST. The surround room is large, but still I only play the system at a moderate level. Aerial speakers are known to love power, so my experience may not be the same as someone else would have with increased power. However, because of the value of forums in helping me make decisions, I wanted to post my experience.
Incidentally, James Tanner strongly urged the upgrade to the 14BSST for the Aerials and his advice was the final straw. As usual, he was correct. Michael Kelly also encouraged the increased power. Again, in the absence of local dealers, the time and patience of the manufacturers is invaluable.
