Bi-Amping

I thought that was your question, rather than biamping which is using two amps at once. You cant just hook up two amps to one speaker, as the signal from one amp will feed into the other amp through the combined speaker terminal connection. If you are trying to compare two amps, you need some sort of switching box to isolate one from the other so only one is hooked up to the speaker at a time.

Exactly-- the reason I came up with the idea is that I have a reverse box hooked up to my RCA outputs from my DAT that changes the L & R stereo channels.

I was hoping to configure the same sort of thing so as to compare amps on the same spkrs w/o actually changing the spkr wire hook-ups. Does anyone know if such a component exists?

Thanks for comments all.

This would probably be somewhat impractical as a separate component would be needed for L & R spkr.

If your preamp has balance control, you can swap sides and figure which one is better.
