Interesting review Malcolm. So I guess you didn't get a chance to try the new BAM with the old MMe? I've been complaining about the "slight" brightness (try a violin concerto or sonata) for awhile now. Although few people have chimed in with the same issue. Rumor has it that the new BAM quells the issue. I'm not willing to sell the MMe and buy the MXR just to see if it solves the problem.
The lucidness in sound with an increase of volume is probably due to the lack of brightness you were hearing before.
On the other hand, how is the low-level clarity? At what level does the speaker sound balanced? I've always felt that the MMe needed a little volume to sound good. They're not breathy at low volumes. This is one speaker where a remote to adjust the volume is essential.
