NAGRA System
At left from top to bottom:
Precision Compact Disk Concept player
The CDC is a top of the range CD player. This unit is equipped with a built-in digital to analogue converter, remote control and pre-amplifier stage and can be connected directly to a power amplifier. The front-loading mechanism is designed with aviation technology giving an excellent stability to the transport and reliability second-to-none.
Battery operated tube pre-amplifier with phono stage
The PL-P vacuum tube pre-amplifier is a high quality pure class A tube based pre-amplifier including a high precision phono stage for vinyl records. With its unique internal rechargeable battery power supply, the highly sensitive phono stage, features individually hand-wound NAGRA built transformers, is entirely isolated from the mains power supply and hence avoids any form of hum loop. Able to handle both moving coil and moving magnet cartridges and up to 4 independent sources the PL-P is an extremely flexible preamplifier.
MOSFET Stereo Amplifier
The MSA is a stereo power amplifier giving 60 Watts per channel into an 8 Ohm load. Its physical footprint is identical to the compact Nagra range, of CDC, VPS, PL-L and PL-P.
