Dual volume control - it should be standard

With my dual volume control pre, it turned my Bose 201 into Kaiser Kawero. Unbelieveable!!

Knghifi,
Congratulations!That`s quite the feat.

Thanks Charles. It saved me $64,823.87. I had Circuit City mod my pre before going out of business for $176.13.

For the 1st time, I play Springsteen not only in my car but home system. I just dial the volume controls until it sound like a 192kHz/24bits download.

Basically I can dial in any sound I like, SET, OTL, Horn, SS ... whatever the mood at the moment just by playing with the DUAL volume controls. Sweet!!

Not the worst idea I've heard, but pretty damn close.

I prefer single volume control on preamp + left and right gain controls on the power amp. Preamps with L + R level controls can be hard to match channel levels if they are not stepped and accurate. As a test, try matching (continuously variable) L & R pots by ear with music, measuring the results with test tones and posting your results.
