I have a 6 bsst2,7bsst2,14bsst2 and a bit 15.I just got a new 3bsst2 last week and I noticed that it hums louder than the rest of my amps.it's not a real loud hum, but it is noticeable because the other amps are very quiet.is this common in The 3bsst2 amps,or is there something wrong with it.also I noticed that it gets just a tiny bit quieter when it gets warmed up.

I have four Bryston amps including a 3Bsst (not 2) and it is quiet; can't hear a hum even with my ear on the top of the amp.

Just turned my system on and all is quiet for the moment.
