innovations beyond superlatives

Revolutonary volume control

 

The volume control is a patent pending technology that allows perfect level matching with a much more transparent sound compared to pots and switch resistor technology, because there is no attenuation of the input signal, just an automatic selection of a tap on the Nagra custom output transformer.

SUPER CAPACITOR POWER SUPPLY

 

The newly developed SuperCapacitor power supply is a new technology which combines the very low noise of a battery with the high current capability of the best linear power supplies.

ADVANCED mechanical isolation

 

The audio engineers created a super vibration free stand to lower the microphonic resonances to a new level.

Tube NOS circuit

 

The HDPREAMP has the best specifications ever achieved by any tube preamplifier, 160 dB of signal to noise and 5 Hz to 200kHz frequency response with perfect phase integrity. The impedance input is 50k oHm and the output impedance is 0.2 oHm so you can drive any amplifier on the market.
