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 100ohm and 47Kohm (47Kohm is use for MM or MI or high output MC cartridge).
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 balanced (10Vrms RCA max.). 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 5Hz to 50Khz +/-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 (loading impedance 47Kohm, gain roughly x4-x5) , to make the output level par or higher than regular CD output level, and get enhanced dynamics over the regular MM input.
You will need to pay at least $8K-10K from other manufacturers to get a phono stage with barely close or even worser in sonic performances. Some even ask $5-8K for a solid-state or $8K-10K tube MC/MM phono, which are built with printed-circuit board instead of our best sounding component-to-component and point-to-point hand-wiring.
Separate MM and MC inputs, so that you can connect to two TT or two tone arm with cartridge at the same time, and select by the MM /MC switch on the fly.
6SL7(default) / 6SN7 balanced XLR output stage available, for someone who have XLR balanced input in the per-amplifier, and get the further enhance in dynamics.
Very low noise and super high gain (80db = x100000) design, work with 0.3mV MC cartridge without any problem, and can easily boost the output level over the regular CDs or DACs.
Solid-oak side panels with hand polished thick aluminum chassis for optimum tonal balance by metal + wood combo, which can make both metallic (horn, triangle, electric guitar...) and wood (violin, guitar, piano...) musical instruments sound more real and organic than just all wood or all metal chassis.
Removable tube shields for best shielding effect and easy to replace tubes when needs.
