I have a CAT preamp and wanted to try a remote control. Other CAT owners talked about the Placette Audio unit. I contacted Guy Hammell at Placette and ordered their volume control unit with a 30 day trial. The CAT is one of the most transparent preamps available and the Placette didn't degrade the sound at all. The Placette preamp has the same remote unit built into it so I would imagine it is an excellent preamp. Guy is easy to work with and accessible and you can't beat a 30 day trial period. Good luck.
