I am preparing an open-project for MM phono preamplifier. The sample has been built, lot of measurements and listening done. Some preliminary info may be found here:

I am sorry the paper is in Czech, but images and schematics should be self-explanatory. There will be a web page in English soon.

I am looking for commercial available and currently manufactured pre-pre head amps for moving coil cartridges or complete RIAA head amps, where such an input stage is integrated (like Threshold SL10).
Therefore I start this thread:

Perhaps one of the members know some examples - thank you very much.
