I have a Denon 2700 which, offhand, I think is about 27 pounds and I have it in, I'd guess you'd call it a consumer grade Gusdorf a/v rack. If I were to upgrade, I'd be going to a heavier receiver, certainly over 30 lbs, or maybe over 40 lbs (I think the 4802 is about 45 lbs.) I was wondering if people that have these, or similar receivers generally have to buy specialty (i.e. expensive) a/v racks, build their own racks, or is consumer grade stuff (O'Sullivan, Bush, etc.) adequate? Would reinforcing the shelves of one these work, or be necessary?
