Separate volume controls for left & right channels

My Audible Illusions Modulus 3 and 3A both have dual volume controls. It may take a bit getting used to, but IMHO there is nothing like it for the flexibility and pureness of the sound. It is better than a balance control which I think degrades the sound.

From a purist standpoint it is better to have dual volume controls than a balance control in the signal path.

I had a preamp with dual volume controls once and it drove me nuts making the two channels match. Not that I was unable to do it, just that I always had the nagging feeling that I didn't have it right. A little bit of psychology and audio nervosa in play there. While it's true that there's more flexibility, the process of adjustment, listening, further adjustment every time I sat down to listen is not tenable to my expectations of instant audio gratification lifestyle.

If the dual volume controls are stepped attenuators then I'm ok, but a smooth continuous knob made me batty.

One of the advantages is better channel separation, or if you want to control right/left without a balance control.

In theory they are better, in practice I agree with Wilsynet; I had one and it drove me crazy.
