IMHO, Mac would NOT be a good match.
As I've stated before, the Mac is rated into 4 ohms, which gives the impression of more power than it actually delivers. (Universally, mfgrs rate in to 8 ohms).
I am not damning the Mac, I like it's basic sound, and even went to New York and attended McMasters Training, which gave me a real appreciation for the 'hands on' nature of that company, in terms of build.
It's just that the Mac is 'softish' in the bass, with a bit of 'bloom' and sponginess which would not do well with the MBL...Besides, we're talking about electronics, I believe, when talking about MBL, which cost a bit more, aren't we?
Congrats on chosing from the line that I think makes the best speaker on the market today.
Best,
Larry
