Having tried a ML 32 here in my system as well as ARC REF 1, and REF2, CJ 15 and 17, CAT ultimate, BAT VK30, VK30SE, VK50SE in my system using 33H driving Aerial 10t's, The VK50SE was the clear winner and remains to this day.
I'd recommend you add it to your list to try, and good luck.
Wonderful synergy between 50SE and Levinson 33H.
