I'm the proud new owner of a 3802. I was hoping to site it on a shelf which is open at the front and back, has plenty of space to the left and right but which has only 1 inch gap above. The manual advises a gap of about 4 inches, so would anyone anticipate any over-heating/ventilation problems with my proposed position. The 3802 doesn't seem to generate too much heat at normal listening levels, but I'd appreciate any comments from that huge user base out there! Thanks in anticipation.
