Wright Sound WPP specs please


Wright sound made a few phono preamps, the WPP-100c, -120c and -200c, maybe more. Can anyone tell me specs for each of these, particularly Output Impedance and Gain? I believe that the 100c has 2 k-ohm and 60 dB. What about the others?

I see references to the WPP120 on line when i google but its not much. Anyone know of such a beast?
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:

So how did anyone decide between the WPP100 and WP200, if the specs were the same? Obviously they use different tubes, but why? Did one replace the other?
Yes, the 200 replaced the 100. The 100 used 6ER5 tubes and the 200 used the classic 12AX7. I'm only guessing here, but I'll bet George got tired of people complaining about the noisy 6ER5 tubes. In the very beginning, he could have just designed a 12AX7 preamp like everyone else. But, he didn't because the 6ER5 was a superior way to go for a more transparent and alive sound. This tube was never designed for audio use, so it can be difficult to find a quiet set. But, when you do... this is what makes the sound of the 100C so special. I'd never trade my 100 for a 200.
Now, I hate to repeat myself because I bring this up every time a post shows up about these preamps. I am on a personal cusade to tell the world that you must try using this pre directly into the amplifier's input instead of through a linestage. The 12AU7 output tubes have plenty of oomph to drive an amp directly. You have removed tons of redundant circuitry and cabling from the system. It's a whole 'nother animal. Use the gain pots for volume control.
I second the concept of avoiding a linestage. "Use the (phono pre-amp's) gain pots for volume control" is absolutely right.

But usually we have more than one source, and we don't want to shift interconnect cables. We would like a selector and a centralized volume control.

So, even better, remove the Wright's inexpensive gain pots completely, then run it into a high-end passive pre-amp, such as the Bent Audio or Music First Audio transformer based pre-amps. Then run CD players, tuners and everything else with no line-stage also.
