Bryston 7B ST - Sounds anaemic. Any help?


I bought a new Bryston 7B ST recently to replace a 94 model 4B THX to drive my bass and I was hugely dissapointed. I wonder if there is a possibility that it may not be pumping 500w as it supposed to do. I have Alon Circe speakers.

I just don't get the oomph factor and I feel the 4B THX kicks better.

Would appreciate suggestions

1) Have the unit checked, even the best lets a little quality issue slip out from time to time.

2) However, a bigger, higher current amp gets a lot tighter grip on the woofs, and may have just corrected the looser boom sound your used to. As such it will sound less bassy.

3) Does the bass sound tight, tighter than before? Then see #2 again.

You can wire a resistor from the caps to gound to discharge the caps more quickly if you like. It is my less than humble opinion that you end up with two choices:

1) Discharge the caps, which produces heat the whole time the amp is on.
2) Add a relay which can (if done correctly with gold contacts doesn't) degrade the sound.

Last I don't believe that any transient signal has any place near my less than robust tweeters. In my opinion this is a design oversight, and is unacceptable.
