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!
