I have a denon AVR 3300. It has a fault whereby sound to all channels cuts off intermittently. When it works it's fine. Isent it abroad to the denon agents who said that there was a dry joint on the digital board which they sorted out. However the problems persist. To send it back will cost more and I'm not sure if I should spend more and risk not getting sorted. Does anyone have any experience with this? A friend of mine is keen to upgrade his 2802 for a 3805. If he does I could buy his 2802. This has lower output than the 3300 but is 6.1 instead of 5.1 and has prologic 2. Is it advisable to buy it or is there a risk that after a while it may also go the way of the 3300?
