I'm getting separates. The amplifier weighs 70 lbs. According to the Bell'O website, the maximum recommended weight for the tempered glass shelves on my AR-711 stand is 50lbs. My current Onkyo 919 receiver weighs over 50lbs and I've had it on a shelf for a couple years, with other components sometimes. I've probably put 55-60lbs on that shelf. So here's my idea. If you see the AR-711 either on my website or on Bell'O's site, you can see that there are four identically sized tempered glass shelves built in and one large tempered glass "topper" shelf. I'm thinking of going to a local glass shop with the top shelf in hand and asking them to make me a piece of either tempered glass or plexiglass (whichever's cheaper) that will hold 70+lbs. I will then put the amplifier on the top of the system. Sound like a good idea? Any hints for dealing with glass shops?
