PHA-200 - uppföljaren till PHA-100 finns nu för provlyssning hos Hi End of Sweden. PHA-200 är den ultimata step up'en för dig som vill ha maximalt ur din MC-pickup.
Här är info från producentens hemsida,
The most unusual feature of the PHA-200 is its amplification method. Conventional phono stages or step-up transformers are designed to accuratelyamplify the very low output voltage of moving coil cartridges. In contrast, the PHA-200 extracts the maximum current signal from the cartridge, and thenthis current is converted into a voltage high enough to drive a conventional line level pre-amplifier.
In the PHA-200 the coil of the cartridge is short circuited or terminated by zero ohms, consequently the current from the coil is much larger than withconventional voltage amplification.
All cartridges have magnetic distortion caused by nonlinear characteristics within the magnetic materials of the cartridge components. These distortionshave an adverse affect on the sound quality.
By using current amplification and extracting the current signal, themagnetic distortion of the cartridge is significantly reduced. In other words the linearity across the reproducible frequency range for the cartridge is improved. As a result the PHA-200 is able to amplify the original cutting signal on records as precisely as possible.
The sonic advantages of the PHA-200 compared to conventional phono stages or step-up transformers is immediately apparent. The neutral soundstage, rich mid-bass and smooth highs are most impressive. The overall sound quality offers improved transparency and resolution.
