I know it's been said that using a speaker switcher between a power amp and multiple sets of passive speakers is not a good idea since the switcher will likely introduce a momentary no load situation to the amp during the switching and this is not good for the amp.
So then, let's say you have an amp with a speaker switcher following it etc... and you simply turn the power amp OFF before switching the speakers? How bad is it to power the amplifier off and on several times a day? Not 50 times, but say just 3 or 5 times max?
I know it's been said that, typically with electronic gear, it's better to just leave it on all the time as opposed to turning it off each night, the temperature fluctuations wear the components faster. But, let's say you have a power amp (non-tube) that's been on for a few hours, then you simply shut it off for 1 minute to switch speakers, then power it on again, and you do this say three times a day... how bad is this to do? I'd imagine there wouldn't be much temperature fluctuation if the amp is only off for one minute. But does powering on and off fairly often cause other types of wear or damage to the amp?
I know that most guitar amps have a "standby" switch so you can swap speakers and do things without having to actually power down the amp... too bad that common audio power amps didn't have something like this also.
Finally, I'm still trying to figure out the best way to add two pairs of speakers to one single amplifier and be able to switch back and forth between the two pairs of speakers without harming the amp.
Sure, it would be nice to just have two dedicated amps, one for each pair of speakers, but two issues with this: 1., a second hi-end amp means another very large expenditure, and 2., having two amps powered on all day, everyday, as opposed to one, is going to use a measurable amount of extra power over time. Way more economical to use just one amp.
