B&W Nautilus 803 & Musical Fidelity A3

Hi all.
I've recently upgraded my hi-fi, substituting the B&W DM570 with a pair of Nautilus 803. The amplifier is a Musical Fidelity A3. I've some problems about this combination. I've gained in a lot of aspects (clarity, frequence response, smootness), but I've lost in the soundstage, that is not defined as well as the DM570, especially with music containing a lot of instruments where the sound is a bit "jammed" (I like rock, jazz, but also classic music). After a lot of experiments about loudspeakers positioning, I think this could depend on the amplifier, that has not enought current to drive the loudspeakers.
Is it true? Have someone some results about this combination? Could be the upgrade to a Musical Fidelity A308 a good solution? Or are there other best combination in the same level of price ($2000-$3000)?
Thank you in advance your useful tips!

I have the N802s and found that the placement of the speakers is critical for the best sound stage & imaging.
Currently, mine are at least 4 feet from the rear walls, about 8' apart, angled to face the listener (around 30 degrees from straight on) and I sit about 10 feet from each speaker ... needless to say it is a trial and error approach until you have them focussed.
It is best done by 2 people.

As to amplication, I drive them with 2 Belles 350A monos (800 watts) and a Belles 21A pre-amp.
My current room is too small (13 by 17)... they like a big room 16+ by 20+ ... and they love power ...
