Do you always keep the Amplifier powered on

by all means...had i3 and i5.3...on all the time...sims are build to last.

I run my Parasounds 2003mod/5250v2 & Pioneer 74-txvi 24-7.
They defiantly sound better, oppose to turning them off.

Based upon the recommendation I got from McCormack, I would leave my DNA-1 Deluxe turned on 24/7. They claim it definitely sounds better that way.

But, I now am using a Krell FPB 400cx, and, because it gets so dang hot I just can't make myself leave it on all the time. I guess I just have fears that anything that gets that hot may be a fire hazard. And it does seem to sound better after a couple hours.

Well , it may depend on where you live .
I live in the lightening capital of the country !
I have , so far , lost a microwave oven , television and a heat pump compressor to lightening strikes !

Good luck .

When I had my Simaudio i7 integrated I left it on all the time, but on standby when not playing. This is strongly suggested by Simaudio.
"The Standby button disengages the input section from the rest of the i7's circuitry and turns off the digital display. However , when in Standby mode all audio circuitry remains powered up to help maintain optimum performance." (from the Simaudio manual)
