Linear PH-1 Phono Stage.
The Linear PH1 is an phono stage specially designed for low output moving coil cartridges.
The most unusual feature of the Linear PH1 phono stage is its amplification method. Conventional step-up transformers or Low noise amplification are designed to accurately amplify the very low output voltage of moving coil cartridges. In contrast, this extracts the maximum current signal from the cartridge, and then this current is converted into a voltage high enough to drive a RIAA phono stage.
All cartridges have magnetic distortion caused by nonlinear characteristics within the magnetic materials of the cartridge components. These distortions have an adverse affect on the sound quality.
The Current Input Design always makes the optimum adjustment for the pickup system. By using current amplification and extracting the current signal, the magnetic 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 LPH1 is able to amplify the original cutting signal on records as precisely as possible.
The sonic advantages of the LPH1 compared to conventional phono stages is immediately apparent. The neutral soundstage, rich mid-bass and smooth highs are most impressive. The overall sound quality offers improved transparency and resolution.
