Bricasti M1 vs new M3

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.

@sfseay, Thanks for the information.  Please let me know how the MDx install goes.  It sounds very easy but is it really?   

Anyone know just how much trickle down tech the M3 receives compared to M1 SE? Is it the same circuity minus 1 power supply or are there other differences? I would imagine Bricasti keeps some design exclusive to M1 otherwise M3 would cannibalize sales, but that's just speculation. Any thoughts or knowledge there?
