dual volume controls?


I see a few pre-amps with dual volume controls, which I would assume are for true dual mono designs-like the Quicksilver or Audible Illusions Modulus 3A-is dual volume control inherently better? Isnt it a pain in the ass to adjuster each control everytime? Thanks.

Seems real inconvenient,why not take it a step further and have two mono block preamps with separate power supplies?

I wanted a no compromise volume control but also wanted all the conveniences of a remote so I had Blue Circle build a custom motorized 47 point dual mono Shallco attenuator for my preamp.

In a world where the sound of cables and power cords are considered different it's odd how folks can't hear the ill effects balance controls have on sound Rrog. It would seem much easier to shift one's seating slightly.
A balance control can be very useful in bringing better soundstage focus. To say that the need for a balance control indicates problems elsewhere in your room/system is just plain wrong. If a designer/manufacturer can't design/implement a reasonably transparent balance control, then they probably aren't competent to design/build an entire preamp.
