Just wondered if it is expected for a AVR's and amps to have short life span or should they last till you are done with them and want something new. i seem to get like 1-2 years from a AV have have Marantz, Denon, Onkyo Anthem and Yamaha. The Yamaha got fried by a power surge from the cable company. the rest last 2 years at the most. they are getting to expensive to fail that fast in my opinion.\nwondered if others have had the same issues.
