Bryston 7B ST - Sounds anaemic. Any help?

All power amps that I have owned did something similar. Ask Sean, but I believe it's the storage caps that are discharging.

Dear Nanning,
I have observed the same noises with my 7Bs. I agree with PBB that it is probably from capacitors discharging. It is disturbing but not damaging. There are ways to prevent these sounds, but obviously this was not done for our 7Bs. I am happy not to pay for extra circuitry. I left my 7Bs on virtually all the time anyhow.

Ok, thank you for putting my audiophiles' mind to rest. I guess at Bryston less is litterally more (sounds...)

;-)

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.

Hi Everyone,

I guess the amp just needed warming up and yes, the bass is more controlled and of course the legendary Bryston support and response within 24 hours did help. Whatever, Bryston is about the best co there is out there, hi end stuff at real world prices and they are over zealous in customer satisfaction which is always a nice feeling. The oomph is perhaps due to over extended expectations but the tonal balance is there. The FM Acoustics gave me more slam though.

Problem solved and happy listener and always a Bryston fan. Glad I bought the Bryston instead of the Pass Labs or Krell.
