Is DEQX a game changer?

I am a newly minted PreMate owner examining the possibilities.
A couple of thoughts:
1) I know I will want Roon capability so is it possible to upgrade to the 4th gen processor?

2) Earthworks m23's are widely available at sub $500. I would be interested in a group buy to drive that price lower if others care to participate?

3) Has anyone attempted to use a USB converter from the 232-ComPort w Flirc to have wireless display & control?? 

Great thread & I appreciate the education. I am way behind the curve but will be contacting Larry Owens soon.

And man do I love the idea of a DIY open baffle speaker project with Deqx Processing!

Using a standard M23 will not have the correct DEQX calibration file unfortunately so be very careful. It will not work without this. 

Yes. I use DEQX with OB speakers & am now building my second pair as a 4-way, powered by an HDP-5 with an HDP-3 as slave. 

I actually sold my $20K+ speakers and now use my new DIY speakers and the DEQX.

^^^^any picks of the speakers ? How much did they cost to build ?
