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?

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.
TD 160, not sure what is going on there, but every combination of amps and preamps I have tried has yielded better sound in my system straight into the power amps. As usual, I guess I should have stated YMMV. Perhaps the Wright is too high output for your amp section, or there is some sort of impedence mismatch between the tube and solid state components. I am using 15 watt tube amps so maybe I need the high output. My gain pots are usually set between 9 and 12 o-clock for live in the room listening. This is with a mm cart. Perhaps my "crusade" should end since I cannot control other system's variables. Anyway, you did try it and if your impressions went the other way you would have been very pleased to find a free tweak right under your nose but undiscovered. Now I am curious, I would be interested in hearing from anyone else who has newly tried this and whether or not it works for them. In what kind of components is it a step down in performance?
