Class A tube stereo preamplifier
Nagra’s engineers have taken as a starting point the critically acclaimed Nagra JAZZ preamplifier and, incorporating elements of the design philosophy that characterises the HD DAC, have created a preamplifier that delivers even more performance and musicality for an exceptional listening experience.
The Classic PREAMP is the ideal partner for the Nagra Classic AMP and Classic DAC.
