I think it might depend on how old you're talking. I have a fifteen[roughly] year old 4B-THX[NRB?] that sounded very bright when I tried it in my two channel rig. But I bought it only intending to use it as a sub amp so musicality didn't really matter.
There has been discussions in the forums that with every upgrade the Brystons became more musical. I'm just guessing, but the difference between an old 4B like mine and a newer 4B-ST might be big while the 4B-ST and SST might have a closer sonic signature.
