I recently received my Level One speaker set from HTD which I learned about on this forum (NICE!). They sound great with my new Onkyo ds494 receiver. So I hooked up the powered sub to the pre-sub out jack on the receiver. My question is when I turn the receiver (or put it on standby), should I always turn off the power switch on the back of the subwoofer. Or is it ok to just leave this on all the time. I don't think it shuts off automatically when I shut the receiver. Secondly, what's the benefit of the standby setting on the receiver and is it a problem leaving it on all the time. I know it means you can still power up using the remote (which I plan to do anyway). But should I still be using the main power switch sometimes so the receiver isn't always on. Stupid questions, yes but I am learning thanks to this forum.
