Pass Labs XA-25 on all the time?

My Pass Labs XA-25 stays on most of the day. It does sound its best about an hour after it turns on. I'm thinking of leaving it on all the time. Does this help or hurt the amplifier in some way. I  have a PS Stellar S300 in another system that stays on all of the time. It's a class D amp so it uses very little power at idle . PS recommends leaving it on. It sounds better to me that way. Other than the power consumption, is there a downside to leaving the Pass on all the time? Thanks Larry

the only downside is the electrical usage, but it is probably not much on the XA25. The XA160.8 left on uses the same electricity as three 100 watt older type light bulbs...I just spoke to Pass about his...no harm to amp and it does sound better, so usually only turn it to standby when not listening for a few days...

I'm inclined to leave it on. It does sound better after being on for an hour. After that, I'm not sure it's not just me wanting it to sound better. But, heck there does not seem to be much downside. I've owned a  Threshold 400A since new. I did turn it off because it gets a good bit hotter than the Pass. That practice and time probably contributed to the caps ultimately requiring replacement. Time probably had the larger effect.  Thanks for all the answers. The XA-25 is very special. Larry

I always left my XA30.5 on! So yeah, keep it on.

Since the "A" in "XA" means "Class-A", do the math to determine how much A/C will be wasted leaving it on constantly. You may be unacquainted with how a Class-A amp works and get a surprise on your next electric bill.
