A:Answer I found the latest version of the manual online, which is dated December 15, 2014
From page 2: The top surface of this stand is designed for use with a product weighing no more than 300 lbs.
From page 11: The bottom shelves can only support 95 lbs. while the top can support 300 lbs.
Note that page 2 also includes specifications stating maximum weight as 300 lb, which is obviously misleading (i.e., it's top shelf, not total capacity).
I also posted images of these pages.
After purchasing/returning another stand that turned out to be way too unstable, I purchased this one for $239.24 in 2011. It looks fantastic and is built like a tank.
I have a 92.6 lb 60" plasma TV on the top shelf, a 38 lb (7.9 x 24.8 x 13.2 in.) center channel speaker on the middle shelf, and a 28.2 lb A/V receiver, plus a 37.5 lb tube amp on the bottom shelf.
If you are planning to place a center channel speaker on the middle shelf, I highly recommend getting some wedge-shaped isolation pads. This will angle the mid and high frequencies (which unlike bass are directional) up towards ear level. They will also eliminate low-end vibration transfer from the speaker to the shelf.
Hope this helps.
