Phono pre-amps match impedance. They amplify the signal near the source in some way like a tv pre-amp.

Basically you still have a cartridge (needle) that has some impedance on it. Each brand and each model had different impedance's that are way high. I forget what the one's I used to have were, maybe 28K ohm or something. Normal audio ranges from about 4 ohm to maybe 28 ohm. You won't get any sort of quality if you don't match all the inputs to the outputs.

jefro, the cartridge is a Rega Exact Mk2 moving magnet phono cartridge. The output is from 6.8 to 7.2 mV. I don't really know what that means, and I don't know the impedance. Here's a link - http://www.rega.co.uk/exact.html

What does "matching all the inputs to the outputs" mean in this context?

I apologize for the dumb questions. These kinds of things are in the realm of faith and magic for me.

Would you know which of these might be more appropriate for my cartridge?
