Two receivers, One set of Speakers

[dbomberger]

OK, I have Forte III's currently in use with my receiver for TV and musical uses.  I am also about to purchase an Integrated Tube Amplifier. I want to use the Forte's for both.  What is the best type of switch to use to accomplish this-or is this a bad idea in terms of lowering the quality of music via the extra switch?  Thanks in advance.  I don't have to do it this way, I could just have a separate tube based system by swapping out the Forte's which I'm willing to do if there is a good argument(s) in favor of that.

Separate system is the way to go.

You want to biamp what now? 👍.   Don't make your head spin unless you have a dedicated stereo preamp and dual amps with gain controls. Otherwise, experiment failed.

You will need a 12v wall-wart to kick the switch over to the 2nd amp.    I like to put the wall-wart on a power strip with the 2nd amp or on the switched power out on the amp itself so that it switches over as soon as the amp comes on.  

 

Also, arrange your process so that you never have the tube amp on while not connected to a load (speakers).  I understand that this doesn't always cause a problem but it can in some cases.

Here is an older post with a similar desire.  One post being mine,  just having separate runs for each amp for simplicity sake.

Thanks!  That is what I am considering doing.

I had the same situation - I bought a receiver that had preamp outs and a Mcintosh ma252 - this solution worked perfectly with my Fortes and HSU subwoofer. Awesome setup without running the risk of two amps burning themselves out. Run Spotify thru my Yamaha receiver and power the fortes with the Mcintosh and run my turntable and cd directly to the Mcintosh - Best sound system in a home I have ever heard. When I want to run 7 channel I'm still using the Mcintosh to power the Fortes. I'm very happy with this solution

That's exactly what I use, works great.....plus it will handle up to 600 watts.

Here's my 2 cents:

Terminate the speaker cables with banana plugs. Wire the amplifiers' speaker connections to one of these:

With the amplifiers powered off, you simply plug whichever speakers you want into whichever amp you want.

Use something like a Niles AXP-1 to switch the RCA output (e.g., from CD player) between the amps.

This can serve many amps, and many speakers, and has no amp power limitations, and no concerns about frying an amp because of what's going in inside a box.

I have this installed in several systems. Works great.
