Keeping your Pass Labs Amplifier on all the time

XA160.5 keep them on standby it only takes about 20 minutes for warmup. Best of Luck

I agree, not really any difference between leaving amps on or off, still takes an hour to sound good, I keep my amp completly off, fire it up from cold, i do this to save on capacitor life more than the power bill.

I keep in standby mode until Friday morning then leave on through weekend since I listen a lot on weekends. It does sound better after a couple of hours. I have the xa30.8

I have XA60.5's and leave them on continuously for days, and every so often turn them off over night.

My electric bill went up $20/mo, over turn on one hour before listening.

I do not like to wait an hour before good playback, and they sound better after 2 days on.

I listen 3 to 4 hours every day.

Power transistor failures can occur after too many cold-hot temperature cycles.
