Got word yesterday from M-audio tech my sent-in-for-repair or refund is
NOT repairable for known issues, and purchase price for MT2 is being refunded.
So
for sure unbalanced input noise issue is now officially an MT2 'product feature' as explained by M-Audio.
However, although not mentioned, the 88.2K bandwidth shortcoming with MT2 applying wrong filter
may still be firmware corrected, but I'll never know for not getting the unit back to bench test.
I hope for owners of MT2 using 88.2K mode
at least this issue is not a 'standard feature' and will eventually be fixed with a firmware update. So those using 88.2K sampling rate might still have a non-addressed problem with ~ 20,000 cycle bandwidth limitation until further notice.
So no MT2 technical review, and I will continue to use my MT1 as the better Microtrack model version for acceptable analog input performance reasons.
