Phono Stage Eq-Preampilier
The Concerto Plus MC is High Edition Concerto for 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, just as importantly, the Concerto Plus MC 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. The Concerto all hand made by "point-to-point" .
Features
Huge dynamic
range,
both the beautiful tone color and wonderful rhythm ,
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 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.
he
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 , it become the sound better
than popular Concerto .It can fight down many
USD$6000 phono preamplifier !
