Despite my best efforts to avoid further expenses for Headfi, I found too good a deal on some pre-populated B22 boards to pass up.  So now I am trying to source the rest of the components as cheaply as possible without sacrificing performance.  
 
I will be going balanced for the B22 and have found these two options for a balanced potentiometer in my current budget:

Do you all have any other suggestions for around $50?

just use the digital volume control in your source? - at most a fixed divider for proper gain structure

Shunted 2 deck pot is a personal favorite for balanced amps.

Can you point me in the direction of more information?  I found an old thread that linked to another forum that has moved.  I can't read the diagram from the old thread.  Thanks!

Dsavitsk's photo in this thread:

under configuration "B" sums it up. 
 
Start with resistors each about half of the pot value and go from there. It kind of depends on how much gain your amp has, VS how little it needs.
