As some forum readers might remember, I was for several years the happy owner of a Camelot Uther DAC. Aside from the great sound, the Uther was a full featured control center which allowed remote control of the volume and channel balance in the analog domain. Being able to "dial in" the volume from the listening chair is a very handy (and even addictive) feature .....
I am quite content with my current Decware ZCD player ..... but the one thing I really, really miss is the remote volume control. Steve has made remote volume control an option for the ZCD, but I decided that I would prefer the remote volume control from the CSP2 preamp ..... which would also allow me to control the volume of a (soon to be purchased) FM tuner that will feed the second input of the CSP2.
As it would happen, I have an old Rotel Surround Sound Processor that was kindly given to me by the friend who built my SO Imperials. This Rotel unit has a remote motorized volume control.

Parker Audio Dave came up with a scheme to use this Rotel unit in a way that would give me a high quality remote volume for the CSP2.
We wanted to have a high quality potentiometer and found a highly regarded TKD motorized potentiometer in the Michael Percy catalog.
Dave used the wireless circuitry in the Rotel to drive the TKD pot which was mounted on the CSP2 .....

We will "pretty it up" later ..... but the setup works wonderfully and I am now able to perfectly dial in the volume from my listening chair. The TKD is one very fine potentiometer.
While we were at it, we also installed on the ZCD player a 100K Alps Black Beauty pot that I had in my parts stash.

After a discussion with Steve, it seemed like a very good idea to have a variable output on the ZCD ..... and there is no question that there is a "sweet spot" as to the input voltage that the CSP2 is receiving from the ZCD. I'm still having a hard time believing what a positive improvement this has made.
Bottom line ..... I am one very happy camper as I sit in my listening chair and tap the volume control until the lead vocalist assumes a 3-D perspective in the middle of my listening room .....
Three cheers for Caintuck Engineering .....
