There are no reviews that I'm aware of yet.
I have a silver one on order with AV-sales, there was a problem with the European shipment (got hijacked

) so it's been delayed a little. I was quoted a 2 week wait almost a week ago, so if your after an amp RIGHT now you would have to look elsewhere, if you can wait a week or so it should be worth it.
I went to buy a complete setup, SVS speakers/sub with a Pioneer VSXAX2AS Receiver (similar features, same price band) from av-sales but was told by one of there installers/techs that the 804E would be a far better amp for my speaker combination and so decided to wait, figured whats 2 weeks considering the cost and how long I'd have the system for, it gives me time to position and cable my speakers anyway.
As there are no reviews yet, you would be buying blind, for obvious reasons I cant recommend it yet other than to say it seems to fit you needs
