Purchased a DSpeaker Anti Mode 2.0 from(made in Finland) several years ago....easy to use, oodle of possible settings.....but I settled on equalizing signals below 200 Hz....with a sub woofer(Velodyne) and Harbeth 40.1's in my large room, the bass is incredibly realistic and natural. I paid about $1000 for this but you might be able to pick up a used one for less
I can not live without "Room Correction"
Accuphase DG-28
I had been using Accuphase Digital Equalizer since 2001.
It is still working fine.
With room correction, the overall balance is much better with tighter base and flat high frequency.
I can not live without it.

Recently Lyngdorf got very popular with good room correction capability.
But I am a tube guy enjoying good timber out of it.
I will not go for Lyngdorf as amplifier.
But I recommend other people to try room correction.
If you are curious, you can try used DG-28 from Japan at 1,700
