Two amps into one pair of speakers


This is a newb question, but my friend has two integrated amps hooked up to his speakers, one McIntosh and a Prima Luna. One is connected with banana plugs and the other with spades. He said this will cause no problems as long as they are not both sending signal at the same time. Is this true. It just seems a little strange to me.

The peanut gallery chiming in here...  :)

If I were to use two amps on a speaker that had lugs for the bass module, and separate lugs for the mid + tweeter module, I'd find a cleaner way to bi-amp.  I'd use this - on the Pass Labs XP-30 and XP-32 preamps, there is a master volume control on one set of XLR/RCA outs, then there is something called a slave pair of XLR/RCA outs.  This "slave" output, its gain or volume control is controlled by a pair of small knobs on the front of the preamp; one can fine tune the "slave" output so that if one is using a less powerful amp for the mid/high speaker module, one can trim the "slave" gain/volume controls to obtain the right balance between the bass and mid/tweeter modules.  It's a very trick feature built into these preamps.  As the saying goes, I'm not sayin', I'm just sayin'...  :)

Just to clarify what one poster stated: you CAN run signal from one pre amp into two amps (via simple Y splitter), or?

Before I got my custom switch built by an EE friend (it's setup to protect a tube amplifier at all times), I used 10AWG Blue Jeans speaker cables with the welded banana plugs and just swapped cables back and forth with my home theater receiver.  I'm still using the switch and it's the barrier to upgrading speaker cables as there's more cables required and a clear sub optimization in the setup.
