It's Magnepan 20.1's or B&W Nautilus 801's

Ok, I have narrowed my speaker choice down to either Magnepan MG 20.1's or the B&W Nautilus 801's. I have heard them both and like them both. Unfortunately in different locations with different electronics. No chance to A B them

Here's my setup: 18 X 18 foot dedicated room with "A" frame ceiling 10' at center. Source is primarily CD (BAT VK-D5SE - tube output stages); Tube Preamp: BAT VK-50SE; Amps: Pair of Aragon Palladiums (SS, 600W into 4 ohms), Aragon 8008BB (dual SS monoblock 200W into 8 ohms, 400W into 4 ohms).

Prefered Music:

Acoustic Strings: Bella Fleck & Flecktones, Tony Rice and Norman Blake Acoustic Guitar.

Classical: Motzart piano Sonatas and Concertos,

Light Jazz: Diana Krall (who doesn't like her !)

I am new to this and really need an expert's advice. I like the sound of both speakers. Since I am a novice audiophile it all sounds good to me compared to what I have been using ! I am sure as I become accoustomed to a high end system, my tastes will be more specific. Help me choose something I will like when I finally get there !!
