Volume imbalance


When I adjust my dual volume control I can almost never seem to get each channel to equal out.  I can adjust one side but then it's just a little bit louder than the other. I believe it's the nature of the tolerances of the stepped Alps pots. I've got room for the Khozmo controls. But I'm not sure if this the way to go. I'm looking for opinions/experiences or suggestions. Thanks for any help. Would an audio taper pot be ok?

At the price listed above for a stereo pair it would cost the same as two mono Khozmo stepped attenuators. Eyeballing it would be tight but they should fit. There would be even more room if I pulled out the 20db attenuation switch between pots that I've never used and I'm wondering if this in the signal path when switched to 0db?? I wish I was more techy. 
@yogiboy you were right, he fixed it, over the phone : ) 

He suggested going between detents as pots are continuous. Bingo! 

Doesnt address the quality issue vs. other options but my chief issue is behind me for now. Thanks all who chimed in. 
Make sure you adjust volumes in mono mode.
Sometimes channels mixed unequally.

I’m glad it worked out .You’re always better off getting it straight from the horse’s mouth!
