Bricasti M1 vs new M3

Do the current m3s come with the upgade, or is it always an upgrade

@sfseay,  Thanks for the information on the MDx processor update to the Bricasti M3 DAC.  

Where did this information come from?  I do not see it posted on the Bricasti Web Site.

What is the cost of the Bricasti MDx processor upgrade?   Does the M3 DAC need to be returned to Bricasti for the Mdx upgrade or is it a local software upgrade?   Thanks...

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:
