Is there a way to switch one set of speakers between two sound systems?


This may seem nutty at first, but it's been suggested as an unorthodox solution to a tricky configuration problem.  Before dismissing it out of hand, I thought it'd be worth asking for constructive feedback on Audiogon.

Is there any way to switch a single set of speakers between two different amplifiers without compromising sonics?  Switching would be done often, so the mechanism would have to be easy -- preferably with a remote or the twist of a dial or even done automatically by sensing input signals, and definitely not involving moving cables.

If this is confusing, here's a simplified example: A listening room contains two systems, one solid-state, one with tubed components.  A single stereo speaker system has only one set of inputs.  Is there any product or configuration method that would like the speakers to seamlessly reproduce signals generated by either system.  Since the two amps would never be playing simultaneously, the speakers might merely play any signal that reaches them, like MartinLogan subs, which  automatically play any signal received at any of their three inputs.

I understand that a “simple” 2-to-1 junction box would not be so simple in an audiophile environment, especially when routing amplified signals from components that might have greatly different output-stage characteristics. 

Any ideas?

I take the cables out of one amp and put them into another. Pretty cheap and effective!

I have two stereo systems in a credenza  Tube amp and SS amp Each amp has it's own set of speaker cables with locking banana connectors Depending on what I want to listen to with what amp, it just takes a few minutes to swap the speaker cables to the speakers

Same with me. Different amps, different loudspeaker cables. Swap takes short of a minute.

Yes easy peasy  Goes without saying, make sure amps are turned off when switching cables

I recently found myself in the same situation as the OP, wanting to A/B compare 2 integrated amps with one speaker. My solution allows me to switch 2 amps remotely between 2 sets of speakers; however, only using 1 set of speakers right now. I added 4-2 source selector switch as well, but not remote controlled; Using it as 4-1 with RCA hard y-splitters to amps.. Wanted all cables to be on the same footing for a fair comparison, so purchased all new 'journeymen' quality cables from WBT.

Speaker Switch is:

Douk Audio VU3 Dual Analog VU Meter, 2-Way Amplifier/Speaker Switch

Source switch is:

Audio Switcher

I can now switch amps from listening position. I can also switch between 2 CD players and 2 phono amps, but not remotely.  Works well, binding posts on amp/speaker switch are decent quality (all this stuff is made in China so...) as are RCA connectors on source switch.  PM me if you'd like to a pic of setup.
