Dual volume control - it should be standard

They certainly make the presentation of space more correct.
I don't often use them for each individual cut unless something is very wrong but always do for each recording. And, yes, especially for analog recordings or those digital transfers that tried to preserve as much of the original recording as possible including noise and unbalanced channels.

Rrog, you are about 200% right. It took many years, a lot of reading, and more than a few peso; but the dual volume controls helped.

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!!
