I have MBL 111b speakers which are also fairly hard to drive. Have tried a few different amps and settled on the MBL 9007s. Hands down the best. Stick with MBL. Get the biggest pair of mono Amps you can afford.
MBL 101e mk 2 Speaker Owners?
I may be acquiring a used pair of the MBL 101e Mark 2 speakers and am wondering what other members here use as an amp to drive them? This is other than the MBL amps.
