Problematic if you are talking about tube gear that doesn't like to be on when no speakers are connected, but no problem with solid state.
Just have a friend hook up one at a time - a swap of interconnects from one to the other (when muted, of course) takes a minute - turn them off if worried about it.
Listening blind and not knowing which is on is the acid test of whether you are really hearing a difference or imagining one based on cost, expectation etc.
