I used to own the Musical Fidelity M1SDAC with a pair of M1PWRs too - it is a fine system that I'm sure you will enjoy. The build quality is good, sound quality good and there are lots of features (like bluetooth) to keep you busy.
I have also auditioned the Audiolab MDAC and thought it was very detailed, very bright - but with the right speakers would be a killer system. Also has great build quality and good looks.
If I were you I would go with the M1SDAC - synergy is all important!
