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 think that your lack of sufficient power may be your problem. B&W's need power! .. The more, the better!

I have way over 600 watts per channel on my B&W's and they are rated at 93db sensitivity. Although I have never passively biamped my speakers, I think that may be the way to go. When I actively biamped mine, I realized the biggest improvement that I have ever made to my system.

Good luck.
