Bricasti M1 vs new M3


I've been using and loving an original Bricasti M1 (not SE) for awhile and have been offered a fair price for it. Is it worth selling and getting a new M3? Anyone have any 1st hand experience comparing each unit?

I emailed Bricasti about what features and functions the MDx upgrade offered, and they replied with what I posted above.

My understanding is as of March 2020 all new M3s have the MDx upgrade. The cost of the MDx hardware was $720.00 shipped to me. I will install it in my M3 next week. The hardware upgrade was shipped by Bricasti and Fedex is supposed to deliver them on Monday, June 22nd. I will post what is replaced with the MDx kit when I receive it.
@sfseay,  What is involved in installing the Bricasti Mdx upgrade kit?   Is the install something the the average person can install or is it more complicated?  Thanks for the update.  
Bricasti reports "MDx Upgrades are performed at the shop in Boston. The new processor will offer improved accuracy and performance so its a worthwhile investment but you can do it anytime. It is a little less money at the moment since we have an introductory price of $700 and then they will sell for $1,000".   Please see:

@hgeifman just replace the old M3 board (the one on the left with the digital inputs) with the new one. Remove some cables and screws, install the new board and reassemble.

I will swap out the board on Monday when it arrives.
