2ch amp and HT receiver connected to same speakers

What have you done to eliminate the ground loop?

Install banana plugs on your cables for a quick disconnect when you switch between systems. Never run with both connected at the same time.

Well I finally found the solution to my dilema of wanting to run 2 amplifiers on one set of spealkers. I wanted to run a HT receiver form multichannel and a 2ch amp for stereo music using the same speakers, To do this you usually have to have a preamp with a HT bypass or set up a tape loop. However, I found this product by niles audio, its an amplifier switcher and its good up to 600wpc and is 12v triggered, for only $95.

Now the question is, can I hook up my zone 2 of my AV receiver'2 preamp and use this as the 2ch side with a dedicated 2ch power amp. I'll be calling Niles and Adcom on this one.

This appear to be the best option of not destroying anything albeit a little inconvenient especially if one often switches between music and HT frequently. I am doing the same thing in my system.

I am not too convinced on the Niles switch box as I believe it may degrade sound quality with an extra box inserted into the chain. Bill is on the right track in contacting both Niles and Adcom as some amp manufacturers may not recommend doing this out of technical reasons(not associated with sound quality).

I use banana plugs to change amps with the same speakers.
