I'm using an Ayre VX-5 Twenty to drive a pair of KEF LS50s. I'd like to occasionally use a pair of Cary 572 SE monoblocks. Would having both the Ayre and Carys connected to the KEFs create a problem even though only one would be active at a time? The Ayre uses spades, the Carys bananas.
Almarg gave me a detailed explanation of why shouldn't do it at Audiogon. I suspected it was not something I shouldn't try, but I didn't understand why. Now I do.
I buy most of my components used, including Cardas Clear Day cables that are longer than I need. I'll have the cable cut and a banana plug installed at one end of each cable, so it'll be spade at each amp and banana at each speaker, making it easy to switch speaker leads.
The amps may both be damaged.. even if one is turned off.
I wouldn't do it. The unused amp will apply a low impedance in parallel with the speakers and could potentially cause the working amp to blow up.
I married the perfect woman. The downside is everything that goes wrong is my fault.
A perennial question about a bad idea.
First, you must assure yourself that you are perfect and will NEVER make the mistake of having both amps on at the same time. Second, you must be certain that both amps place absolutely no load when unpowered. With a tube amp, that is unlikely.
