Symphonies Ver2 High-Definition Tubes Line Preamplifier
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.
Some customer and Audio Critic feedback
“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!”
