All hand-wired, pure tubes high gain MC/ MM Phono pre-amplifier with variable MC gain control

This is one of our newest design pure tubes phono pre-amplifier with MC and MM input capability, it is completely component-to-component hand-wired with high quality good musicality parts. Selectable MC input impedance of 200ohm and 47Kohm (47Kohm is use for MM or MI or high output MC cartridge connection),

This phono stage use all tubes design, with three 12AX7 for MC and MM circuit. Very high dynamics and good resolution along with smooth and sweet tonal quality. Maximum un-distorted output voltage up to 20Vrms. Which can give out same or even higher output level than regular CD levels (typical LP output level is just 1/4 of CD output level) .

RIAA +/-0.5db accuracy 20Hz to 20Khz. MC section 10Hz to 30Khz +/-0.1db

It gives 40db gain for MM input , and 40-80db variable gain for MC input. You can also use MM cartridge with MC input and set to proper setting, to make the output level par with regular CD output level, and get enhanced dynamics over the regular MM input.

VR version equipped with output level control, someone can even skip the pre-amp and directly hook up to power amp. The super high gain of 80db with super low noise floor performance, you can use even low-output MC cartridge and get satisfactory result.

You will need to pay at least $4K-5K from other manufacturers to get a phono stage with barely close or even lower in sonic performances. Some even shamelessly ask for $7-9K for an all tube MC/MM phono made with PCBs.
