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

It doesn't hurt it... each time you power on/off you have some thermal stress which you avoid, so that is better, but all devices wear with use a wee bit.

I also use Class D amps, and they are awful for about 24-48 hours.


Best,
