2 amplifiers connected to 1 set of speakers


I’ve been in the hobby for a few years and my wife asked me a question that stumped me.

Can you have 2 amplifiers, connected via their own individual sets of speaker cables, connected to the same pair of speakers at the same time? I told her I didn’t think that would be advisable.

The question came about when she saw me disconnecting cables from my solid state amp and connecting the cables from my tube amp. (both were off of course). She asked me why it wouldn’t be ok and I started babbling that the signal from one amp would then travel through the other set of connected cables into the amp that was not in use. Even if the other amp was off that could be problematic. If the other amp happened to be on then it could prove catastrophic for both amps and potentially cause an electrical fire.

What is the correct answer fellow audiogon members? Ralph?

Ghasly, your answer in your original post is the correct one and the best answer here. Both amps will be connected to each other and bad things will happen. Even when they are not both turned on. Keep doing it the way you are now and nothing bad can happen.
