Thank you Sergei, very interesting approach! Just a quick question... what about the HiZ area when using BAV99/BAV199s? I mean, using a 1G resistor makes very easy to isolate HiZ section

Why don't you make one up with your BAV99s and see if it results in a good mike

"Bootstrapping doesn't help with the noise." - do you comprehend English ? I was writing about reducing THD - NOT noise. "Guru" - I don't give an LGBTQ about gurus. "BAV199" - available on

You need MUCH less leakage in your diodes for noise. Guru Wurcer recommends BAV199 which has 500x less leakage than BAV99 and no. Bootstrapping doesn't help with the noise.

I thought of that "Interesting idea, I have no idea if it's a good one but depending on the pin out, you might be able to glue the chips together in a stack and the make solder bridges for the

Some of us have not heard a U87 yet ;^)? I would guess it sounds nice but is not a faithful reproduction of what it hears, without harmonic-content being favored in any way.? I would suspect THE #1

Has anyone got ANY evidence this is the shape of the 'hump'? "ChinaMod+U87hybrid.doc" in my Files, details my search for this but in the end had to fall back on what various gurus thought was the

Gareth / leon, I'm glad that you like my recordings, thank you very much. Next step for you: consider this: My very first recordings I made a year ago. The stereo effects were not particularly clear
