I have the same question as parabolic.
The only things I keep powered up are my SS phono-pres.
On some sessions I think I hear an improvement after 20 minutes, on some I notice no change. The ones where I do notice a change are usually playing LPs vs digital sources. And usually with a DL-301 vs a Shure V15.
