what is the best way to add remote control

Since no one has suggested it yet I will: The Clapper!

"Clap-On, Clap-Off"

Radio Shack has a remote on-off switch cheap - can be configured to handle multiple gears.

But I wonder if there will be a quality loss by adding anything to the path - isn't direct as possible better?

(not including a power conditioner - I love my $30 oneac power conditioner off ebay - gonna upgrade someday - made a believer out of me of power conditioning)

I will experiment with mine to see if quality loss is there - in a few days.

But meanwhile, your radioshack has an affordable solution - it can control lights too - handy for bedroom when we are about to doze off.

well, thank you all for your suggestions. One thing I discovered is whenever I cut the power from my amps, then apply it again I still would have to go to the on/off switch and turn it on. it has one of those electronic standby switches. so non of that will work.
thank you again

Myoussif,

Since your amp has an electronic power switch that doesn't
"latch" - i.e. stay on without power - and you don't have
a 12V trigger - then manual operation is the only way.

The best way is not to add a remote control if you care about the sound quality.
