High quality equalizers

A similar question also for hearing loss compensation  but does anyone know of an affordable EQ solution that has adjustable, 2 ch or Left vs Right?  My loss is more in one ear.  Wondering if best solution is simply 2 Lokis.  

if your speakers have L-pads, you could try that first.

Anyone have opinion on what something like an ART EQ341 might do for this application?  Seems popular in the mixing/studio realm but not sure what to expect for SQ in the audiophile world.   2 ch EQ, both balanced and unbalanced. Inexpensive at $150. Unfortunately I have 2 line sources but a passive multi input switching device is easy to find.  

It would seem to me that for an eq to be truly effective, it would need to allow the user to randomly select numerous frequencies and to be able to adjust slope. Perhaps a digital eq could provide better custom tailoring?
