Musical Fidelity A3.2 or A3.5?

Has anybody out there thrown these two on the comparison bench?
Does the A3.5 really top the A3.2?
I would love to hear some feedback about the two.
I will be powering B&W Nautilus 804s, tough speaker.
I haven't heard either of these integrateds, but if I were in your shoes I'd go with the A3.5. More power is always a good thing when using SS and driving difficult speakers.
Have not compared these but either should work just fine. Are you using integrated or separates?
Both of those pieces are integrated amps.
