...if you let it turned on all the time?
I have made the experience that my B60 sounds better after one day. And even better after two or three days.
Do you have similar experiences or is this all imagination?
James, what does Bryston think?

Anything after a hour or so, shouldn't make an audible difference. A few seconds after power On, the caps are as charged as they are going to get and the coils have their fields established, and the only thing changing is the temperature. After an hour, that's stable, too.
If you're convinced you hear a difference, check to see if the heat of keeping it on has affected cable attachment. A not quite tight cable can make a difference in the amp's belief about the speaker load - and that can change things.
On the other hand, if you think it sounds better on all the time, leave it on. Even if it's all in your head, that counts.
Me, I turn stuff off when it isn't in use: it makes for one less component that's going to get slapped around by summer lightning storms.
