NAGRA HD PREAMPLIFIER UPDATE


As there is really great interest about the all-new Nagra HD preamplifier here are few more official details:

"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."

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.


The audio engineers created a super vibration free stand to lower the microphonic resonances to a new level.
The HDPREAMP has the best specifications ever achieved by any tube preamplifier, 160 dB of signal to noise and 0 Hz to 200kHz frequency response with perfect phase integrity.


The HDPREAMP is able to reproduce a square wave at 16 Hz.





Frequency and phase response. - Green: frequency/Red: Phase 
And the Sound!

The HDPREAMP reproduces music with natural impressions, with full spectrum bandwidth and extreme stability.

It also produces a precise 3D holographic soundstage. It is very difficult to express the impact of this design as we didn't think it was possible to achieve such an unbelievable result.

Pure emotion..."
