Dirac - worth activating?

Definitely worth trying.  I bought an Arcam SR-250 AV 2-channel receiver which comes with Dirac Live.  It required a bit of a learning curve but made a huge difference in a pair of Martin Logan speakers.  I was so impressed that I bought the Mini-DSP DDRC-24 for my main system when I was trying to integrate a pair of Legacy Focus speakers in a smallish room.  Again, a huge improvement but I ended up selling the speakers because of their size/weight.

I have a streamer with dac.  Not sure if a mini dsp is possible since it goes between digital source and a dac.

I'm not familiar with your setup.  In my situation, the miniDSP DDR-24 is inserted between the preamp and power amp.  The link below goes to the manual.  Check out section 4.4 beginning on page 23.

Yowser,

thanks,

how is minidsp working out?

As mentioned earlier, I sold my Legacy Focus speakers and now have Reference 3A Reflectors.  I have yet to insert the miniDSP as I'm in the process of moving to a different house.  My intention is to first prepare the listening room with acoustic panels and then insert the miniDSP afterwards.  As you may have noticed in the manual, there's a bit of a meticulous procedure to calibrate it and I only want to do it once. Also, there's several very good youtube tutorials of Dirac Live that were very helpful.
