Artemus, it's not a great situation you're in, but what can you do? ;-) You have an all solid state system, so in theory, it shouldn't hurt anything to leave it "always on"; all of it, unless it's drawing too much current at idle, but I bet it's roughly two 100W lightbulb's worth for the whole system.
I never got that much into the details of UPS's, not even with my computers, because frankly I haven't had to. So your best source for information is the manufacturer. The trick is knowing what questions to ask;-)
I would first explain that you have an expensive audio system which you'd prefer to leave "always on." That you'd like protection from ordinary surges, but that your real problem is from momentary power outages; specifically the damage that quick power turn on can cause to equipment which hasn't had a chance to fully shut down before restart. And do they have units which address that issue; meaning units which inject full power INSTANTLY so your equipment remains on, whether idling or in use, as if nothing happened? And of course, would there be any affect on sonics, especially when the unit was just in 'standby'?
I wish I could say more, but life is all about asking the right questions, so maybe that will get you started . . .
