The HD PreAmp has the best specifications ever achieved by any tube preamplifier, a floor noise lower than -160 dB and 5 Hz to 200 Hz frequency response with perfect phase integrity. The impedance input is 50k oHm and the output impedance is 0.2 oHm so that you can drive any amplifier on the market. It has a super vibration-free stand to lower the microphonic resonance to a new level. It's newly developed SuperCapacitor power supply is a new technology that combines the very low noise of a battery with the high current capability of the best linear power supplies. The volume control, the object of a new patent, allows perfect level  matching with a much more transparent sound compared to pots and switch resistor technology.
