Andy,
I have the same problem (intermittantly) due to my allergies. The hearing in my left ear comes & goes.
I did own a Rowland Consonance preamp that was the best pre I've ever seen for balance adjustment. You could push right or left balance, one channel would go up a click, at the same time the other would go down. The digital display showed exactly where you were at.
It was a breeze to use.....
I can't use headphones when the problem is extreme, it makes me wince!
