Accounting for slight hearing loss

On a whim and with a suspicion, I recently had a hearing test and it showed some loss in left.  Mainly around 3k and then recovers some above that.  I had noticed (after many good tips gathered on Agon) after really paying attention to set up and room, featured vocal/instrument was often right of center, almost never left.  Mind you, i still hear all freq, even quite  high and get great staging but often, its annoyingly with a right bias.  Maybe that's where he's supposed to be!  Thats actually not a trivial point.  Funny thing, I can listen to MD Kind of Blue in mono and I sense no shift. Quite opposite as instruments still have some staging. Go figure.  

Any tips or tweaks to compensate?  Ok, here's where I might be all wet.  Lower resistance to tweeter in left XO (phase issues with right?)  A mod to extend left baffle above the tweeter some?  Simple "Left" on amp works but isnt freq specific.  Im suspicious that using an EQ unit will degrade overall sound although that seems the most obvious.  Do they?  Speakers are Madisound kit Klang+Ton NADA designed with Scanspeak Illuminator drivers.  In Lee Taylor cabinets.  Amp is Rogue Sphinx V2 (A/D). 
Thanks in advance.  Otherwise it's a tad "L" on the amp.

OP:

Here is an idea out of left field:

This is a headphone amp with built-in DSP. It's a little pricey for a thought experiment, but thought I would share.

I would experiment with just turning the balance a little to the left. Or maybe sit in the center, close your eyes and have someone else turn the balance till it sounds right? You get imaging information from the mids/highs. The lower the frequency the harder it is to pinpoint the source direction (think subwoofer). Once the imaging is correct I doubt you will notice one speaker is slightly louder than the other.

Problem is he has a "notched out hearing attenuation" in the left ear only at 3khz.
That’s why the Loki will be good "hooked up to the left channel only" then you can bump up the volume just at 3khz, while the other channel stays flat.

I used one of these DEQ2496 EQ's between CD and DAC (AES or TOSLINK SPDIF in/out - all digital) and think that , especially with 12AU7 tubes in the path further down the line, that the EQ would be considered rather transparent. (Some experience in a modern studio environment would be helpful for setup though). This sounded better to me that the software ones I tried (which was years ago), even those within a DAW. I have 2 MiniDSP-HD's and assume those would be easier to use, but I never used the digital to digital version.
You may be able to get one with a trial period.
