Dirac Live Calibration

I do not know for sure. You have to take that up with Martin Logan but what you showed me indicates that it can be done. 

If you go with subs the MiniDSP and Dirac would be the ultimate set up. Either the plain SHD or the Studio will replace your preamp. If you go with the studio you will need another M1 or perhaps one less expensive one like a Benchmark for the subs and use the M1 on your Martin Logans. The Studio setup will be superior to a regular SHD.  Dirac Live and the subwoofers will blow your mind. You will never think of an analog preamp again.

That is the correct model. 

@mijostyn OK, this is sounding scary, but fun! So, I need a second DAC for the subs?

The M1 is pretty pricey, maybe I could sell it and use the funds for 2 decent  replacement DACS?

I was gonna use the Schiit Modius DAC for my subs. It's only about $250 and measures and sounds great (for subs). It has both RCA and XLR outputs. Check it out. I have the Laiv Harmony for the mains DAC. I regret having to replace my Benchmark HPA4 pre-amp, but if I sell it, that will cover the cost of the DSP and the extra DAC.

@koestner Thanks, so I'm a pretty lay person with regards to this type of stuff. Is it really as easy to set up as some others here say? I really don't need another rabbit hole. lol

@navyachts  I don't plan on doing it all at once. I have good knowledge of crossovers and parametric EQ', so I will set that up first and fast. After getting the most I can from that, I will tackle the Dirac thing. I have done some reading on it and I think it will go OK. You don't have to do everything at once.
