Symphonies Ver2 High-Definition
Tubes Line Preamplifier
Retired Product
The Symphonies
Ver2, line level preamplifier
designed by Mr. Chui Sat Sung,
each component is carefully built using "point-to-point" hand wiring and select grade components.
“Alps” volume pots,
“R” core power transformers, “Dale” resistors, “Wima” &
“Phillips” coupling capacitors,
and high
quality copper internal wiring, create a perfect blend of superb electronic
engineering.
The Symphonies Ver2, pure tube preamplifier reveals crystal clear
details, eloquent musicality, with absolute neutrality.
(3) 12AX7A vacuum tubes
are used in the stage and a one 6X4 for the power supply.
Features
Huge dynamic
range,
both the beautiful tone color and wonderful rhythm ,
ultra linear circuit of the line stage designed for the DVD - Audio and SACD source in the New
Century.
uncanny natural
flowing heart-stirring sound that matches any other ultra-Fi products on the
market .
The Line 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.
True listenability…hear it for yourself.
“Audiophiles around the world are about to discover true high-end performance without compromise…”
“At first listen, I knew this preamp was something special…”
“The instruments seemed to float within the soundstage, absolute musicality!”
