Thanks to all.
Viridian, Herman & Atmasphere - seems like you all agree tube life in Class AB amp service is affected by volume level. Guess I'll look into buying some spare tubes!!
Dpac 996 - Don't know what ill effects cranking things up prior to full warm up might have. BUT I too hear an improvement after things have been running a while. Seems a common experience with tubes - but I also thought that with a solid state receiver I ran in the past - the sound opens up. After 1 hr for sure...but I think after a few hours, there is another step change. No quantitative data to back this up - just an overall impression.
Good listening to all.
