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.

The Loki is RCA analog only.  If you want something that sits between a CD player and DAC, this will do the trick:

But... perhaps you should consider a miniDSP with built in streaming? This will not only get you the EQ you are looking for, but also add music services:

if youre going for a mini dsp you might as well retune the entire crossover

Erik, thanks for the leads!  This would likely suffice to "retune" my output rather than differentially doing this on the speakers.  Doing it in the xo would likely result in differential impedance and likely phase curves, between speakers.  Now I need to research how to convert my HPL left ear profile to SPL.  It's a non linear problem but solvable.  Thanks to all who made suggestions.  I love my result to date but can only imagine it improving.  Its actually a slight reduction as I can still hear differences to tubes, sources, and the likes of toe in and tilt.

As a crossover designer, unless you are an experienced crossover designer yourself, this is much harder than you think it is, and what if the results are short lived? :)

An EQ solution lets you adjust by ear and get instant feedback, which you can always improve upon or adapt later.
