1) I don't have a passive in-line mechanical balance control; whether it be a knob or a slider. No one makes that as far as I can tell. The best I can find are noisy mixers, but I need to set the volume of each left-right channel, which is different from a balance or panning control. 2) The lack of line-out functionality from either dedicated amps, or DAC/amps.
