High quality equalizers

If you stream roon has an eq setting you can use.

The Shiit LoKI mini + is the Las test by the company. You can adjust the highest and lowest settings by 6db and the two mids by 12db.

It's actually the other way around. 12db adjustment for the bass and treble and 6db adjustments for the two mid bands. 

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.
