A rookie question re two amps, one pair of speakers


Hello fellow Audiogoners!

So I’d like to be able to power my B&W 683s from two different amps (not concurrently of course).
One amp would be for my 2 channel system and the other (a receiver) would be for my home theater system. So long as I’m not powering both amps at the same time, is it safe/ok/advisable to connect both amps to one pair of speakers?

I’d appreciate any comments.

Thanks much!

@imhififan how is that not good? You need to be able to switch A/B to disconnect the amp not being used. Unless I missed something...
It'll be fine if your careful, and make sure you switch one amp out before you switch the other amp in. Never have both switch in at the same time.

Yes but, it needs to be said a speaker selection switch need to be used back to front.
Amps to the speaker connections terminals and speaker to the amp terminals.

In one word NO!!
As one of the amps will be trying to drive the others output stage, even if not on.
Unless both amps have a speaker terminal disconnect relay when not on for both + and - terminals, only a tech will be able to tell you.
