I too own a set of N802's and would second many of the comments. I currently use a 7 channel 300wpc Sherbourn. Initially, I used 2 of the amps channels to drive the 802's; then switched to 4 channels to "biamp." Wow! what a difference in dynamics when I aded the other 2 channels with the additional power. Like yourself, I want to take the next step and upgrade the amp and have been considering a Pass X350. However, I question what is to be gained by changing to a two channel amp of higher quality. The speakers sound as if they now have the necessary power and the dynamics sound great.
