Which amplifier to drive B&W Nautilus 802?

I have had N802s for 4 years. I have tried several Krell amps with them. I have found, the more power to them, the better. If you can make bi-amping work, do it. If not, bi-wire them. I wish I could afford more power to them but I cannot. So, right now I run Krell fpb 300cx bi-wired.

I will go for Plinius SA100, I heard this combination.
It sounds very good.

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.

In lieu of a couple responses, I agree with the more good power you can give them the better, this line likes power. Jayctoy suggested the Plinius SA100, I disagree with this. I have talked with dealers that agree the SA250 is a nice match but the SA100 isn't enough, furthermore I heard a SA100 on my N803's and it was 'ok', same as the other 100 watt amps I had on them; 100 watts just doesn't seem enough.

Thank you for the feedbacks.
Think I will go for bi-amping, and amp with 300watt in 8 ohm and 600 watt in 4 ohm.
