November 4, 2012 November 8, 2018 John Costanzo Electronics

There has never been an introductory integrated amplifier with the fit, finish and sound of the ROMA 753AC. At first glance, this stunning amp simply takes your breath away. This high performance amplifiers brings out the best of other components in the system. Created by those obsessed with great sound and for those who love great music.The result is 50 watts of pure pentode output per channel built around a pair of 12AU7 on input/driver tubes and a pair of EL34/6CA7 power tubes in push-pull configuration for a detailed, delicate and dynamic sound.

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.
