The description page for the Bee2Quiet states, "the Bee2Quiet coarse and fine stereo switches replace the stock carbon pot volume and balance controls in the BeePre2." Does this mean that the upgrade will remove the ability to adjust balance, or is there still some way to achieve balance adjustments? I listen in an unconventional space that requires some balance adjustment. I can live without it, but would much prefer to have the ability to adjust balance.
