Rotel RA-1570 vs Musical Fidelity A300

I have been running my B&W Nautilus 803 speakers from a Musical Fidelity A300 dual mono amp for several years now. This is/was my first "serious" hifi setup so I've never really had anything to compare it to.

I now have the possibility to cheaply acquire the above Rotel, quite a new model, which is rated lower on wattage per channel but has a bunch of attractive new features like digital inputs, USB etc.

I was wondering if anyone was in a position to comment on its performance versus something like the older MF amp. I'll only be keeping one, and ideally don't want to purchase the Rotel just to test it and have to go through the hassle of finding a new buyer.

Thanks for any help you can offer!
