Magnepan mg1.6 vs mg1.7 bass quality?


Will the 1.7 improve on the 1.6 in terms of bass quality and punch? Maggies are not know for bass punch, so anyone compared both head to head? Will only consider moving to the 1.7 it it can improve on the bass punch from the 1.6. How about toal balance, read somewhere that the 1.7 is brighter and leaner? Would still prefer a warmer, softer presentation.

Currently running a bryston 4bsst2 amp and a cary slp03 preamp

I auditioned the 1.7's about a year ago, and owned the 1.6's at the time. It was a brief audition, because I was really interested in the 3.7R's which I bought. That said, the 1.7's did not strike me all that favorably. I would say, though, that addition of a REL 328 to the 1.7's made an amazing improvement. Completely changed the tonal balance in a very good way.
So, you might want to consider sticking with your 1.6's and adding a sub. Another thought would be to go to a warmer, softer amp. I've just never bought into the maggie/bryston pairing.
Hi guys, so in conclusion, the 1.7 will be much clearer/brighter and leaner sounding than the mg 1.6? I would still prefer warmer, rounder and fatter sounding maggies,
