which nad amp sholuld I get?

I don't think the C320 BEE will do what you want. It's not a real bass grunter, just a nice sounding amp after it warms up. It has less power output (50 wpc) than what you have now.

It's hard to advise you. Why do you want more power? Not enough bass? Clipping on orchestral peaks? If what you want is more volume, you will need a LOT more power.

The 10 o'clock volume position doesn't mean much.

Post some details--how big your room is, what kind of music you listen to, your present amp, and why you think you need more power--and see if anyone has suggestions.

Good luck!

Well, I guess you have to put both your amp and your speakers into the equation. If your present setup is crapping out on orchestral peaks, you have a headroom problem that won't go away with only double the amplifier power. You will need more like six to ten times more.

(This is because of the dynamic range of an orchestral performance. Crescendos and tutti can pack a real wallop. For a peak that doubles volume for more than an instant, your amp needs to put out ten times the watts.)

B&W speakers are not known for their efficiency, and bookshelf designs in general tend to be a tad more power-hungry than larger ones. The solution may be to find a more powerful amp AND get more efficient speakers.
