Concerto Plus MC-Signature Tubes Phono Stage Eq-Ampilier Version 1.5
The Concerto Plus MC-Signature (Version 1.5) is top version of Concerto Plus, It work for MM and MC cartridge with external power supply, phono stage embodies the newest thinking of YS-audio dedicated and enthusiastic technical design YS Chui . The unit has MC input ( Low 71dB of gain , High 77dB of gain ) and MM input ( 48dB of gain ), and, just as importantly, the Concerto Plus MC-signature boasts an very low noise level, so in practical use, the 71dB gain is usable in systems with low overall sensitivity. It uses a EZ81(orEZ80) rectifier tube with solid state regulator for HV B+ power supply , three 12AX7 for the gain stage and Hasimoto HM-X MC transformer for MC step-up stage . MM input is 47K ohm. The Concerto all hand made by "point-to-point" .
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.
The HV B+ power supply is application of a highly
efficient solid-state voltage regulator with EZ81 Tube for current
The EZ81 Tube opens up the soundstage and allows the music to "bloom". The melody flows naturally, like a river.
The highly efficient solid-state voltage regulator give the very good bass controls .
