Color (silver) and looks was the major force driving my purchase of Belkin PF60, it looks so good with Silver Rotel gear!! It also is level 6 of power filter, which I am not sure what it really means, but being top of the line must mean something. I also looked hard at Panamax 5300 as many people recommend it, but it is more expensive than usd 334 I paid for PF60, it is also black and would not look as nice at my stand.
