Not a good idea to hook your speakers up in parallel to two amplifier outputs. That one amp is off will not negate the difference in impedance caused by this setup. What you are trying to do, I assume, is have the capability of driving your speakers with either one amp or the other. A solution may be to make or buy an "A B" switch box. Make sure the switching is 'break before make' and the contact resistance is spec'd very low - a few milliohms. This will allow you to do what you want to do without affecting your system in a negative manner. And don't flip the switch with power on to either amplifier.
System to system
I am fairly new to high end stuff and am still kingda in the learning curve stage.
I have a Cary tube preamp and amp that runs through a set of Harbeth HL5 speakers. I also have a large Sansui G9000 solid state that has been all recapped and brought up to todays standards. I'd like to run the Sansui in my rack as a secondary system to utilize the tuner and power a Sony transport and Lite DAC that are also in the rack. Can I run speaker leads to my Harbeth speakers and hook them up to the binding posts that also are hooked up to my Cary system without causing any damage or feedback? I would never run the systems at the same time.
