Quite a few Bricasti M21 DACs for sale cheap

Having both i2S and LAN inputs is not standard spec

Going forward I believe this will be "standard" having both the LAN & IS2 connections. I brought my own M12 to the Bricasti factory and had the back panel machined to add the IS2 port hole and then they installed the IS2 board as well. I do use their new M19 transport with the IS2 connection and it sounds superb!

@sksos, yours must be the customized M12 I read about that informed me of the possibility.

@tvad I have the M12 not a M21. Not customized just wanted to have BOTH a LAN & IS2 port available so I can switch back and forth between streaming and the M19. We also had another unit updated for a good customer here as well. 

@sksos, I edited my post to correct M21 to M12. Your clarification is duly noted.

If having both LAN and i2S inputs is not standard, and an additional input was added by machining the rear plate and adding an i2S card, then I consider this customization. You might consider it upgrading. I think it’s semantics. The take-away is it’s possible for a fee.

Had this been offered when I updated my M1 SE to M1 Series 2 a year ago, then I would have done it.

The mothership just called me back to tell me that there is a new MDX board. $800. Unclear as to whether or not it's user installed.
