I have 4 of the Iso Orea Bronze isolators that are like new. They can handle 8lbs each compared to the graphite model only handling 4lbs. And they are just a tad bit wider at 2 inches wide compared to the smaller 1.6in width of the graphite. I have a modified bluray player with heavier power supply and lots of dampening added to it so I needed to step up to the next bigger model.
