I won't give a recommentation on the A5, but will talk about my equipment and what I do with it.

My preamp is a Sonic Frontiers LINE 1 that runs with six 6922 tubes. It would use significant power and very significantly reduce the tube life if these were left powered on all the time. However the LINE 1 has a stand-by setting the keeps the tubes a slightly warm with a low voltage. This reduces the "shock" of turning the tubes on/off and reduces the warm-up time for optimum sound. I normally leave the unit on stand-by but follow SF's recommendation to power right off it I won't be using it for more than a couple of days.

My Monarchy SM-70 Pro amps are high 'A' bias and remain noticeably warm when not playing music. They have no stand-by mode, accordingly I power them off when not listening.

But note that I leave both preamp and power amps fully powered-on when I'm not listening for a short period of time, say 1 hour or less.
