I was a beta tester for the 88A-BM. The upgrade consists of both a firmware update for the 88A hardware, and a new DDRC-88ABM Utility program that provides the functionality seen in the screenshots in the announcement. The upgrade was straight-forward, with the excellent documentation we have come to expect from Mini-DSP. Be advised that it will require that the 88A cover be removed to access and move an internal cable, so be ready to remove it from the rack.
Several immediate features that I find very useful are the fact that Dirac trims and delays are now revealed to the user, although they remain read-only. The second feature is the ability to toggle individual channels off and on. For example, if you were interested in hearing what is happening in a set of speakers, e.g. the Atmos overheads, you can isolate those speakers without having to disconnect speaker cables.
Of course, there are many more new features that must be explored. However, I did not have a chance to do much of this testing yet. I think it will be interesting over the next couple of weeks or months to hear of creative ways to use the new features.
Initially, I thought I might be able to eliminate the MiniDSP 2x4 that is being used to consolidate the signals from my four subs. Unfortunately, I don't see how this would be possible, unless I am missing something.
Is the upgrade worth $100? First of all, I think $100 is a fair price for significant improvements in the 88A's functionality. It is not often that we see a software/firmware update that offers so much. Whether the enhanced features are worth $100 to a specific owner, only he can make that decision. I know I wouldn't hesitate.
