Well, I've been playing the Master BAM and RC Networks for about 10 hours now, so it might get even better - but it really does not have to. I've already commented on the VSMs in general so I won't rant about how good I think these speakers are. I will say this regarding the Master BAM, just when you think a speaker can't get better, the MBAM indeed brings worthwhile improvements to the already superb MXe. Besides what appears to me to be quieter background and therefore more transparent soundstage and intrument localization, which are worthwhile in their own right (mind you I always use the BAM in AC mode) the MBAM really shows its stuff on acoustic bass, take a song like Autumn Leaves by Patricia Barber with very well recorded bass, the MBAM creates a clearer sense of bass presence and bloom and articulateness. I'm sure there are improvements from top to bottom, but I've focused on the bass because it was so noticeable, and given that this is, after all, a smallish monitor with an integrated stand, the bass is truly first-rate, at least for acoustic instruments and I really don't think the idea of adding a subwoofer at this point would make any sense - the speaker simply sounds natural and balanced and better than ever. If you own the VSMs, upgrading to the Master BAM is simply a no brainer, you will get improved performance equal to or greater than making changes to sources or electronics. The key to this speaker has always been its approach to producing good bass from a two-way speaker, and the key to that has been the use of the BAM to produce that bass without having to move to a multiple-driver approach with a bigger box and woofer. By making the BAM better than ever at producing bass, it is simply the next step in getting the most from a speaker that might just the most well sorted speaker in the world from years of focus on the basic design and wringing the most that design can give. To say the least I am impressed, and this with my small Music Reference RM10s, next up will be the Atma-sphere M60s and Music Reference RM9 Special Edition, both of which are excellent bass producers, and better amps.....
I can't be sure, but I would think the Master BAM might make the AC versus battery just that much more moot.
