Plinius Audio SA-103 Power Amp

Plinius intends for the SA-103 to be left on at all times, and left in class-A/B mode when idle. If you forget, an internal switch can be set to automatically switch the amp in class-A/B mode after 15, 30, or 60 minutes of no signal, thus saving on heat dissipation and your electric bill. If you’re a control freak, you can turn off this feature entirely, but remember: In class-A mode, the SA-103 sucks almost 500W continuously. I loved being able to leave it on all the time without having to remember to power it down to class-A/B.
