Room correction room system vs ears….

I've used digital room correction for years, first as a plug-in to Foobar2000, and now with Minidsp's Dirac Live box. I rent and am a fixed-income. The former means I deal with rooms that are sub-optimal, acoustically. The latter restricts how much I can spend. The Dirac Live box corrects both frequency and time domains, and for my application, it's well worth it.

The weakest link in most stereos I've heard has been the room. I'd do room correction before I upgraded anything else, but budgets and rooms vary, so YMMV.

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.
