Not sure if the Nautilus 805s are close to the performance of the Silver Signature 25s but... A while back I compared the N805s to the VR2s and it was simply no contest. The VR2s are far and away a better speaker.
Not discounting the B&W / Musical Fidelity synergy, I would bet the VR2s would sound great. Just make sure you've got the room to pull them away from the walls.
