I have the A1.7 & the M1.4. They're both equally stellar performers, as far as I can tell. I don't think the 1.7 offers improved IQ over the 1.4, as far as I can see. Only reason I have both is that I bought the 1.4 first, and the "A" 1.7 happened to pop up virtually free & I wanted a version with the "A" contacts. The build quality on the "M" version is nicer, though.
