Have the 305s, but cheaped out on the sub with a Rockville 10" (still balanced) -- also didn't want a down-firing sub due to apartment living, but the new place has paper thin walls so the Rockville will likely stay in a closet .
Ive owned the Behringer Truths and the lsr305 and lsr306
The Truths were my favorite for sound quality, but I didn’t find them easy to hook up to my PC for desktop stereo. Their gain structure made it hard to match to my onboard sound card. They were also MUCH bigger than the lsr305
