I have a hybrid setup- tube pre and SS amp. Using a Modwright SWL 9.0 Signature with Home Theater Bypass (and Denon 3808CI for 5.1) I would have preferred if the Modwright bypass worked even when powered off, but the 5AR4 and 5687 tubes supposedly have a long life when used in a Pre. Don't know if I'd be quite as happy running tube amps as well.
