MM-Phono Stage Amplifier
|
Shown Images is not the final design and will be modified soon to concept line of the Headphone Amplifier.
What makes it different:
*---------------------[This feature is temporarily hidden as it makes this device completely different .It will be available right before production launching ] . * Entire Amplifier is galvanically coupled and NO capacitors are used in signal amplification path, providing reference sound purity as capacitors influence is completely eliminated . *Used unique tubs with golden grids had been developed for space research and work with Zero Bias allowing to ground cathode without resistor,therefore eliminating resistor's noise. This kind of layout places turntable`s cartridge virtually strait "into the tube". *Very low nose parameters are achieved by remoting the full scale power supply . *Cathode follower output allows strait signal transfer to any kind of Power Amplifier by any length of shielded cables without signal quality lose. This also eliminates necessity of Line stage Amplifier . *Output is decoupled with high voltage polarized capacitors, by the preference of leading Japanese High End audio developers . *Each Phono Preamplifier is burned in, tuned and adjusted to the best technical parameters. |
