That's some very stiff competition that your Vincent beating - amps costing 2 to 2 1/2 times as much. But they are solid state amps, so maybe its the tubes in the Vincent that your are finding more pleasing to your ears. So I would suggest rather than trying another more expensive solid state amp, go with a true tube amp. But it would have to a pretty high powered one like the Hybrid Vincent, as the your B&W's aren't exactly efficient at only 84db.
Or keep what you have brother and enjoy the music. Sounds like you found great synergy with the Vincent and your speakers.
