Hello, first i would like to comment on my reciever. It is a Kenwood VR-209, and it works great except it was dropped in shipping and the front got a little damage, the case doesnt align properly, and it shuts down occasionally at moderate volumes, but other times it doesnt. Does anyone know what would cause this, if it is at all user repairable (i have a small background in electronics) and if not, approximately how much do repairs of this type cost? Secondly, i was wondering if i would notice a major difference in the surround imaging of the system by purchasing an optical cable to run from the dvd player, or running it in digital mode?
