In my search for the right SS amp, (I purchased about 5 amps in a 2 year period), the Moon W-5 came in second place and was the first amp I've heard that peeled away layers of detail. And it was this amp that really helped me realize that amplifiers have tremendous differences designed into their sonic signatures. And it's not all good.
My only reason for selling it, was because of the amp I found to replace the W-5 and because I did not believe the bottom end had enough juice for my Aerial 10T's at slightly higher volumes.
Nevertheless, the W-5 is an excellent fast amp with a touch of sweetness and powerful to a certain degree.
Never heard the 802's, but from what I heard from others, if you did happen to encounter dissatisfaction with this combo, I'd look to replace the 802's first.
My guess is that you will be staying up listening at night later and more frequently then you ever had before.
