Tube life in preamp. Please help


Hello-

Using an Audio Research SP9 and I've shut it down each time between listening sessions.

I find however it sounds better if I leave it in the standby position.

How much does this lessen the life of the two tubes it contains? They were Amperex and not cheap.

Please advise. Thanks!

The one thing that no one has mentioned is the cost of keeping tube gear on all the time. I had an ARC SP9 at one time and it wasn't drawing that much power, but it together with a pair of ARC M100 monos and we're talking $20 to $30 a month in power usage. I also had one of the M100s catch fire in front of my eyes, but in all fairness the piece had been modified. As the years have gone by I have returned to solid state equipment for the reasons that first there is really no appreciable difference in the two technologies at the high end, and that I am more focused on the music than the equipment as I grow older.
