Summary: I purchased this receiver to replace a 15 year old Technics receiver that finally died on me, and I've always been a big fan of Panasonic brands but I was on a budget so I bought this one instead of the top of the line model that I really wanted. This receiver is a little light in the features department to be considered a "Home Theater Receiver". Lack of HDMI and component inputs really limits this for home theater.
Summary: I had been powering my Polk rti-12 and rti-10 loudspeakers with 2 biamped SA-HE75 receivers for about a year, until I got my HK AVR-240s. Over that year I encountered no real problems, other than the lack of power.(Hence the biamping) I don't recommend this Panasonic for anything larger than very small floorstanding speakers with only mid/high frequency requirements. Bookshelf speakers or satellites would be perfectly fine.
