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.
