Room correction room system vs ears….

The goal in room treatment should be a reflected flat response. Yes, absorb the bass but don't also absorb the high frequencies. Just disperse them so they can't ring. I really like racks of LPs as my main treatment. Bookshelves can also help.

In my custom listening room, I have built in bass traps.  I end with a live room, treated on walls, ceilings and floors with absorptive materials.  Trying the same on front and rear walls decimated the dynamics and high frequencies.  I chose to use Synergistic HFT system throughout the room which are rather inconspicuous and tame the high frequencies in front and rear adequately by dispersing them.  So no ringing and a delayed response from hard wood reflective surfaces.  

If you use Roon (if not I advise you to..) you can just make a REW measurement and then manually plug the proposed REW filters into the Roon EQ soft ware. From there add your own adjustments after careful listening. 

I have not used it yet, but I have a Mini DSP Studio SHD which is a DSP unit using Dirac Live, it is placed between digital front ends and the DAC. I have already got a large amount of room treatments and bass absorbers I made myself in the room. I've been waiting for my pre amp to get back and now that I have it I will try it out when I get back home from Florida for the holiday season in Nov/Dec.

Keep your wall treatments 4" suspended from the wall.  Often overlooked.
