Default Has Anyone Tried The P&S Volume Controls?

Has any of my fellow forum members tried the P&S High Performance Analog Volume Control? I'd like to try one in my Gainclone and I'm looking for some comments/feedback.

I've emailed them through their contact information on their website. No response yet.

It seems like their OPC271 device is just hiding a PGA231x or CS3310 that controls an opto-coupler circuit. It might be worth designing your own depending on their price. They look pretty expensive.

or you could just buy Greg Ball's OptiVol kit. If you email him and tell him the supply voltage you'll be using with it, he'll send you the appropriate resistors. And I've heard that it sounds pretty awesome too (supposedly alot better than an Alps Blue Velvet) http://www.ska-audio.com/Forum/YaBB.pl?num=1178438672

Default pricing

They now have a separate website where you can buy direct:
P&S Technologies Inc. - OPC271 Volume Controll
Not cheap, the module all by itself is $205; output boards (depending on # of inputs) from $15 to $57; Control board $179; P.S. & remote $80.
By the time you're done, an unbalanced remote version w/5 inputs shipped to the US is almost $600...and that's WITHOUT an enclosure!
But still, a complete design WITH wireless remote control. I haven't seen any other LDRs with that feature.
