Room correction room system vs ears….

I also agree to try room treatments first.  Experiment with them in different places.  To me, room correction is taking away your true sound and replacing it with something manufactured, I.e. fake.

Minimal 'Inexpensive' Room correction via room treatments is quite doable. There should be little to NO excuse Not to try some things, On the other hand I just got DiracLive and though I have a poor experience wiht NAD T748 and it's early version of room correction, the DiracLive did marvelous things to my sound experience. Don't forget Speaker placement. A couple of inches in any direction and in their placement change everything, If you move you speakers remember that you will have to Retest your DiracLive or they will just be a constant sore spot, Possibly even destroying your sound experience.

Don't spend any money upfront, first hang some rockwool (Home Depot, Lowe's, etc.) on the walls and see if that works for you. If it does, then to make it attractive you will know how much to spend and what to spend it on. Have fun!

I have been using digital signal processing since 1995. It works incredibly well for subwoofer crossovers, full range room control and speaker balance but it has it's limitations. Doing this right requires the right room with all early reflection sites dampened depending on the type of speaker used. You do not want the frequency response drifting more than 5 dB up or down or you will run out of amplifier power correcting the troughs and drop resolution dropping the peaks. Newer processors like the Trinnov Amethyst and the DEQX Pre 4 and Pre 8 are so fast that running out of resolution is no longer a problem at any volume. These units measure, with there own calibrated mics, the frequency response, timing and phase of each individual speaker and subwoofer. They then flatten the frequency response curve, and correct group delays so the the sound from each speaker gets to the listening position at exactly the same time and in phase. Some of then will then overlay a desired target curve. I then measure the main loudspeakers with an independent calibrated mic and make any adjustment needed to get their frequency response within a dB of each other from 100 Hz to 12 kHz. The result is spectacular imaging which is the first characteristic that other audiophile notice.

Electronic Room Correction is a band-aid. It just covers up the problems and is Not a Permanent Solution.
