A local authorized Pioneer Elite dealer is offering a good deal on the Elite 56TXi receiver. The specs for the 56TXi would lead one to believe it should be a robust design with very good sonics. But, a competing dealer shared some critical thoughts on the Elite receivers - especially the reliability and longevity of these Pioneer designs. I could use all the objective input possible from both current and past owner of Elite receivers. What are the strong points here? What specific issues did you experience, if any, with reliability of the Elite receivers?
