I picked up klh-2400 receiver 100 x 2 , a while back at best buy for my bedroom system ,cost $99.00 when i started to hook the thing up i noticed it had pre out jacks on it ,this seemed odd to me that a receiver at this price would have them ,i cant believe anyone would want to use the pre amp section of a receiver at this price point ,just seemed odd to me, btw i have it running a pair of jbl 620s speakers sounds real nice for a bedroom system.
