Not sure what it runs, but the Belles Aria is pretty special, I haven't heard this Model Musical Fidelity, but i've heard other MF, I'm sure its a quality piece and the Parasound is well done also. I haven't heard them on anywhere near the same type of equipment to compare, but I would not buy either without taking a look at a couple of the Belles, The Soloist 1 and the Aria.
Good Luck, Tim
