I have created a most unusual headphone amplifier and a very unique phono pre-amp, I have a couple of prototypes of each and I am looking for critics to critique these for sonic performance.

You interested?

Is it a tube phono preamp? Can it do LOMC? What are the phono preamp gain? Phono cartridge loading selectable?

Thanks for the response. It is not a tube preamp, The sound is very high resolution not flavoring with tube or solid-state sound. It is all about resolution, nothing else matters. Noise messes with resolution, distortion does too, sonic signature (tube or S-S) does too.

LOMC? low output moving coil? if so handels 0.200 Volt just fine with lots of headroom, tweaked for Benz as in Ruby Z.

Gain in moving coil mode is adjustable in 10 dB steps from 40 dB to 90 dB from the front panel.

Front panel loading control for moving coil resistance is 20 to 1020 ohms continuous, capacity in swched from 0 to 0.1, 0.22, 0.47. 0.68, 1.0 uf, MM too but it sounds like that is of no interest (20K to 120k continuious, 0, 33, 68, 100, 220, 470 pf in steps).

What else can i tell you?

Thank you for your interest,
