Live near enough to me in Plainfield, NJ, 07062?
I got hearing aids and a dual 31 band equalizer at the same time, thinking the eq might do a better job if I plugged the inverse of my hearing test into it. Turns out the hearing aids have a program for live music that is full frequency without compression, sounds darn good and the perforated cups allow a mix of sound in to preserve imaging (my biggest concern).
so I am not using the equalizer. It has a bypass switch, zero noise,
Thus you could try it before spending any real money.
from amazon, I took it apart, examined it's innards, it is an exact clone of DBX

btw, why not start by measuring what your speakers are delivering at your listening position in your space with test tones and a SPL?
I could help you find a used copy of this CD with 29 1/3 octave tones (tracks 9-38)
and an inexpensive SPL meter is all you need, you get 'relative' truth, (no need for expensive calibrated exact truth) make sure it has a threaded hole to mount on a tripod at seated ear level
