I've been using a pair of Hsu ULS-15s for six or seven years now. I leave them powered up 24/7 and have not experienced any reliabilty issues. The standby mode is not sensitive enough for the levels I listen at, so they don't "auto-on" unless levels are loud enough to trip them.
I have the pair eq'd with an SVSound AS-EQ1, which does a fantastic job of taming peaks in my room. They've been off the market a few years, but worth seeking out if you have bass/room issues.
