Tube amplifiers that really drive MBL 101E's

There may be no interested in re-starting this seven-month-old thread but I thought I'd give it a shot.

1. The CAT JL-3s seem to be a reasonably sure bet.
Has anyone actually compared these CATs to any of the big MBL 9000 series amps in terms of bass performance?

2. I've heard great things about the Berning ZH270 as well (yup, 70 watts).
