I'd like to learn about volume controls


I've been researching preamps (I currently am very happy with an FT Audio LW-1 passive preamp) and I'm very curious about volume control designs. I know there are different types and different quality. Where can I learn about volume control design, or can anyone briefly explain the differences? Thanks.

Hello,
I seem to recall a article written in The Absolute Sound about a year or so ago, about a product called a Silver Rock Transformer Potentiometer from a Swiss company called Audio Consulting. In addition to a high quality transformer (for noise reduction I believe) they have a unique passive volume control that seems to work differently than most. Sorry I don't remember more about that volume control or the way it works, but I think it would be well worth investigating. Here is a site that may help you start on your journey www.referenceaudiomods.com
Hope this help and
Thanks for listening,

BAT's website (balanced.com) has a description of their research into various types of volume controls that you may find informative. Click on the "resources" tab to get to the "white papers" -- the one you want is titled the "i-series white paper".
I think Melos, Big Dog(?) and TacT have/had some interesting volume controls.
