Hi recently I've became interested in 2 channel audio. I was wondering how reliable are Panasonic receivers of this series. So far I've heard mostly good things about them and have read only about one or two complaints. I'm planning to pair them with Harman Kardon HKB6 bookshelves and maybe a Dayton subwoofer. Also are there any other receivers in this pricerange that I should also consider along w/panny's? thanks!
