Question Aleph P1.7 volume control

I have almost finished my Aleph P 1.7, but I am not shure about volume control. I was thinking about 4 pole 12 positon rotary switch from Elma, but 12 positions is this enough?

Somewhere on this forum I have read once that it is possible to use just a 2 pole attenuators for stereo balanced output: between + and - phase?

This would be a nice solution because it is not easy to find 4 pole 24 postions switch with a fair price, but which solution would serve best?

What do you think?

This could be the best solution, but I have no experience with PICs. And there is still some PCB artwork to do.
