802s are easier to drive,can go with less power,801s especially the eariler matrix and 2 need a minimun of 200 wpc,they sound great but the 15"woofer needs and eats up power,the dual woofers in the 802 are more tighter in my opinion,and the stands make a difference.I would go with the 802s and it,s not because I own a pair it,s that I was able to hear both the 801s and 802 side by side with S/S and even tubes and the 802s sound better.Cant you see why that the new 802 Natilus when they are up for sale on Audiogon sell very fast.
