My 4B-ST runs Hot


4B-ST owners, does your amp run hot? After an hour or so of listening at moderate levels my amp is so hot on top that I can't keep my hand on it for long. I do not think I am pushing it that hard, but I might be wrong. My speakers are some small floorstanding PMCs (FB-1). Curious if anyone thinks this is normal or might be a problem?

Argent,
I'm not familiar with the speakers that you have, but, if they aren't very sensitive or dip into the low ohm range (1-3 ohm) they can make your amp run pretty hot. Especially if you like to listen to your music quite loud. I used to have a pair of Infinity Kappa 8's and they would dip into the 1 ohm range (with sensitivity at about 84-86db)and would make my amp run VERY hot, could even cause the amp to activate it's protection circuitry if we really cranked it up. And this amp had plenty of arse. I now have a pair of Legacy Focus that are sensitive speakers (95-96db and operate @ 4 OHM) and don't have this problem. My amp rarley even gets warm. That Bryston has tons of arse, so either your speakers are the cause, as mine were, or the problem is elsewhere. Maybe someone else has another suggestion. Don't know if this helps. Good luck.
Mullen, glad to hear you love your Legacy's. My wife and I love ours also. An increadible improvement over the Kappa's. Hoping Argent finds out his problem. I'm starting to upgrade and am considering the same amp he is running. Hey, us Legacy owners are at a minimum around here... keep on enjoying!
