Dual volume control - it should be standard

Knghifi, You must really know what you're doing. Anyone else have an experienc they would like to share, possibly with 901s? 901s have virtually no box to resonate, no crossover, all drivers with the same voice and EQ to dial the system in to your room instead of room treatment. Direct/reflecting like MBL, Martin Logan, Magnepan, Mirage, Quad, etc.

My YBA 2 preamp has dual volume controls and everyone who has seen them think they're stupid, maybe not.

Dual volume controls are not stupid, in fact they're highly effective. I first had them on a Superphon preamplifier from PS Audio back in the 80s. An incredible piece of equipment by any measure. They were however; a hassle. I had to adjust them for every piece of music that I listened to. The upshot was that separation and depth perspective were among the best I've had in my various systems regardless of price. Takes your picks............ personally and at this time later in my life, I'd trade the convenience of a remote with volume and balance for the extra enhancement.

It's bad enough giving up remote control.
Stepped attenuators are as far as I'll go.
I'm willing to give up laziness to a point.

I do remember noticing a long time ago that one channel (probably the right) was louder or had more info but I believe it was done intentionally, or so I was told. The brain does adjust.

I had a popular preamp with two individual stepped attenuators with steps so far apart in volume they couldn't possibly used for any type of balance control and just a nuisance. They must be some sort of profit maker for the manufacture who naturally claims a sonic superiority with them.

There are other more sensible ways to attenuate dual mono. My family hated them, in a few short months I hated them. Mine actually wore out after a few short years.
