Balaned P2 Tubes Phono Stage Eq-Preampilier
Balanced P2, phono stage embodies the newest thinking of YS-audio dedicated and enthusiastic technical design YS Chui . The unit has MC input ( Max 75.5dB of gain ) and MM input ( Max 55.5dB of gain ), and, just as importantly, the Balanced P2 boasts an low noise level, so in practical use, the 75.5dB gain is usable in systems with low overall sensitivity. It uses a 6X4 rectifier tube with solid state regulator for HV B+ power supply , three 12AX7 for the gain stage and two 5687WA/B drive Jensen output transformer consist output stage provide true balanced output. Jensen MC step-up transformer provide true balanced input .This MC step-up transformer can good match for 1.5ohm ~ 40ohm output Impedance of MC cartridge . MM input is 47K ohm. The Balanced P2 all hand made by "point-to-point" .
Features
uncanny natural flowing heart-stirring sound that
matches any other ultra-Fi products on the market .
The phono stage made by Hand built " point to point " on YS-Audio factory.
"point to point" has become more focused, the soundstage is deeper.
Hand built by " point to point ' is very high cost of manufacture !
The installation of the tubes line stage is special designed , it can prevent RF interfere and vibrate interfere,
It has become very clean soundstage and saw the musical instrument hang up in the air.
The 6X4 Tube rectification opens up the soundstage and allows the music to "bloom".
The melody flows naturally, like a river. In contrast, solid state rectifiers emit
electromagnetic pulses that resonate throughout the audio circuit and add an
electronic haze that can be perceived as a highly unnatural noise or grain.
The unnaturalness of the solid state rectifier's turn on/turn off cycle creates a choppy,
edgy feeling that over-emphasizes the leading edge of transients at the expense of a
harmonic completeness and does not allow the individual notes to rise and decay naturally.
Beside, It with solid state regulator for HV B+ power supply , the regulator give the very good
bass controls.
The Important features

The output with both RCA and XLR
Jensen MC step-up transformer provide true balanced input .
This MC step-up transformer can good match for 1.5ohm ~ 40ohm output Impedance of MC cartridge.
Phase select switch Normal / Inverse
Gain select switch with 6 position : 1 is MC 75.5dB / MM 55.5dB , 2 is MC 74dB / MM 54dB , 3 is MC 73dB / MM 53dB , 4 is MC 71dB / MM 51dB , 5 is MC 69dB / MC 49dB , 6 is MC 65.5dB / 45.5 dB
The two 5687WA/B drive Jensen output transformer consist output stage provide true balanced output.
External power supply.
All RCA connections use Neutrik , coupling cap use Sonicap and Oil cap.
