Looking for a good pre-amp to mate with Cary V12i

Clio09,
The output impedance of my Herron is 100 ohms nominal. I don't know enough about electronics to say if that would make it an appropriate match but something tells me it would do just fine. Perhaps someone else can weigh in with a more technical answer.

Jond,

Thanks for the response. Reason I ask is that I have read some posts regarding matching based on whether the amp has a high or low sensitivity rating. My current preamp, about 9 years old now is a N.E.W. P-3 (designed and built by Cary). It has 10db of gain and 400 ohms output impedance. Like you all this tech stuff is somewhat foreign to me. Dennis Had recommended a low cost upgrade to me that would allow me to use 6CG7s instead of 12AU7s in the pre-amp giving me an better sound. But I thought before I did that I'd look around for alternatives. A new Herron is probably out of my price range, but a used one could work. The match is the most important thing though.

Can anyone else out there weigh in on this? Thanks

Clio09,
FYI my Herron has 14db of gain and you can usually find them used for about $2K. Good luck!
