Wright Sound WPP specs please

The WPP100C and WPP200C have identical specs:

60 db gain (adjustable)
Input impedance: 47K
Output impedance: 2K

The only other standalone phono preamp George made was the Phono AG. I don't have the specs for that, but I bet it was similar to the 100c and 200c.

Google brings up a few references to the WPP120, but no concrete info. I wonder if this is a typo that turned into rumor. The Way Back Machine can help find old information that's lost when a web site goes down. I don't see any reference to WPP120 on George's site:

When I owned a WPP100c, I was using a passive preamp (Bent TVC) and the sound was wonderful. It was incredibly open with an outstanding three dimensional soundstage. I can't offer any comparisons with an active linestage b/c I didn't have one at the time, but the usual caveats apply. Your system has to be passive friendly for it to work right. The only way to know if it works in your system is to try it both ways.
