Concerto Plus MC2  Tubes Phono Stage Eq-Preampilier

The Concerto Plus MC2 is High Edition Concerto for MM and MC cartridge , phono stage embodies the newest thinking of YS-audio dedicated and enthusiastic technical design YS Chui . The unit has MC input ( 65dB of gain ) and MM input ( 45dB of gain ), and, just as importantly, the Concerto Plus MC2 boasts an low noise level, so in practical use, the 65dB gain is usable in systems with low overall sensitivity. The Concerto uses a 6X4 rectifier tube with solid state regulator for HV B+ power supply , three 12AX7 for the gain stage and low noise KFET class-A 0-NFB point-to-point for MC step-up stage .The input impedance of MC input with select 100 ohm, 1K ohm, 22K ohm. and MM input is 47K ohm. The Concerto all hand made by "point-to-point" .

ultra linear circuit designed for the LP and SP, it has 4 kind EQ network for select , include
RIAA , London ffrr , Columbia , SP. 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
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 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 , it become the sound better than popular Concerto .It can fight down many
USD$6000 phono preamplifier !
