Balanced outputs from my Ayre preamp go to an Ayre amp; single-ended go to a crossover that low-passes to a pair of subs. I want to high-pass from the crossover to Cary tube monoblocks as an alternative to the Ayre amp. When either the Ayre or Carys is not in use it will be in standby, and speaker leads from only the active amp will connected at any given time. Is there a problem with this plan?
I'm using the term amp to refer to the Ayre stereo amp and to the pair of Cary monoblocks.
Thanks for the advice guys. Actually I turn off the Cary CAD 572SE monoblocks when not in use, but I thought to leave the Ayre VX-5 Twenty in standby mode when using the Carys. Turning the Carys off is easy, because the switch is in front. but it's difficult to reach the power switch on the rear of the Ayre. Concern about shorting disconnected speaker leads is daunting, so I'll give up the plan if I can't power down the Ayre.
I've been using the Ayre setup with the single-ended output going to a Beveridge crossover. Low-pass goes to a pair of Velodyne HGS-10s, high-pass to the Carys. It doesn't seem to effect the sound at all. One of the Carys is awaiting a tube replacement, so it has not been operational, so I don't know what effect if any the balanced connection to the Ayre amp might have.
The previous setup used a Cary Cinema 12 processor and Parasound A 21 as the alternate amp. I used bananas with both amps and moved a single pair of speaker cables between them. The sound with the Carys was quite different from the sound with the A 21. My impression is that the sound with the Ayre preamp and amp is much closer to that of the Carys, but we all know how fallible audio memory is.
in the circuit will present a load to the source. I suspect this will not be an issue when the Ayre is being used, but it might when you're using the Cary and the Ayre is turned off.
Try it- you won't hurt anything, but I suspect it will sound better without the extra load and its cabling. OK- I more than suspect it :)
Leaving tube amps on just wastes tube life. To quote the Vanimal, "There are only so many electrons available to jump off that plate."
While I've had s/s amps that sounded better after being powered on for a day or two, I've never heard any improvement with tube amps after the first hour or so. YMMV.

Leaving the amps turned on while connecting anything in or out is a path to blown amps, speakers and preamps..
Particularly if using RCA connections.
Plus speaker wires really have a magic way of shorting when fiddling with them and the amp is turned while doing so.
I have found leaving equipment turned on 24/7 to be great. But I DO turn them off when I move IC, speaker wires and such.
Turning them off for a few minutes really does not lose the always on magic. IMO/hearing of the results.
