Bricasti M3 In the house

I few weeks ago I switched from the minimum phase filter to linear phase; It definitely did something; hard to describe but on most material I prefer the linear phase; overall just presents as slightly more organic and pure, the diff of which is most noticeable in the mids. 
Owners of M1 or m3 please let us know your experience if you played around with the filters.

Listening lately has mostly been hifi streams from Tidal or Qobuz; Roon Radio seems to be growing into a better DJ; Lovin it! I can’t say enough about the performance boost of running Roon core in Rock; with digital sounding like this, I have given up on my desire to build an analog front end. Have a nice day!

I just upgraded my M3 by replacing the digital board with the MDx board.  $720.00 shipped to my home from Bricasti.  A noticeable improvement and a great upgrade if your M3 doesn’t already have it installed when purchased new.
A 20 minute board swap out and as I said, a noticeable improvement in sound stage, clarity, and in the midrange.

@sfseay that's great it was so easy! Mine came with the MDX hardware so it's the only starting point I have experience with; The dealer stated M3 with the MDX digital board surpassed the M1 w/o the MDX; Now maybe someday I might try the latest M1, but i'm pretty darned pleased with the M3. 

I also ordered the MDx board for my Bricasti M21 DAC, they emailed me the invoice and I paid using Zelle. They received the funds in 3 seconds. The technology works. The MDx board is expected next week (I hope). And, yes, I asked Bricasti to confirm they received the funds and they did.

I had someone install the MDx board in my Bricasti M21 DAC and it is working perfectly.  It was an easy install and took about 30 minutes.  After the install, we tested the M21 DAC using his equipment (Bricasti M28 power amplifiers).  My M21 worked great.  

It is now playing in my system.  I need to give it time to break-in but it does sound clearer, smoother with more musical details.
