I will say that Yamaha has it down when it comes to reliability in my book seeing how I used to sell them and have used them in my theater side of my system for years they just don't break and when properly installed and cared for they will give years of enjoyment. If I ever decide to upgrade mine it will probably be to one of the Aventage Yamaha's that have gotten the rave reviews here lately but I am in no hurry everything seems to be good on my setup.
