Leave it on or turn it off?

Seems to me that leaving any equipment on leaves it subject to things like line surges and nearby lightning strikes. Am I wrong?

Unless you have surge protector. But still every time the hair dryer is turned on upstairsm the loud humming noise from turned on amp scares the hell out of me. I turned my stuff on about 1 hr before listening session.

DWPC,
I think that as long as it is plugged directly into the wall and not through a power conditioner, we all run that risk - on or off. It's those dang wires!

Spectral recommends explicitly that their DMA-360 amps not be left on unattended for long periods, because of potential speaker damage during brown-outs or power outs. Check with Classe on their recommendations for their amps.
Dwpc, high quality surge protection should help, but there are no guarantees with lightening strikes.

Glen, I think the best solution is to have an amp that has a standby mode. My Krell FBP300 only needs 2-3 songs before it starts to sound its best because the main circuits that affect sound remain powered in standby. The other less important areas are powered off. I think it uses about 40 Watts in standby, certainly enough to add a few dollars to your monthly electric bill but only 25% of the power it would use powered up.

By the way, leave it off for a while. With the money you save on electricity you can upgrade to the MIT digital interconnect that you want!!
