what is the best way to add remote control

Edesilva, thank you for your comments, I am awar of the Power Director but as you said it is an expensive and not needed in my case because I do have a UPS that powers my entire system. My system is in total isolation from the main powers i.e. i don't need all the options of the Power Director. And my amps don't have 12 volt trigger, all it has a bias control that is connected to the Gryphon preamp.

All I really need is a non-current limiting on/off switch with remote control. do you or anyone else knows of such thing

If the amps have a latching power switch, you can use an X-10 outlet.

Rwwear,
what is the the Latching Power Switch and X-10?

X-10 is a power line carrier home automation system. You can get an RF remote that interacts with a radio box that plugs into an outlet to "send" commands to addressable outlets. You need to replace the outlets--probably need 20A heavy duty outlets. I'm not sure if you can get an IR remote for X-10, the ones I've seen are all RF, so they aren't very compatible with other home automation things, like prontos. Go to http://www.smarthome.com and poke around in the X-10 section.

I played around a bit with X-10, and I think I like some of the other systems better--Lutron's RadioRA, for example. 'Course, these are whole house automation systems, so they can get pretty dear. If you are looking at home automation already, is there something you are installing anyway? If that is the case, can you get an addressable outlet?

A latching power switch stays in the on position if power is lost. In other words, the amp will come back on when power is restored to the recepticle.
