Reference A-300 Power Amplifier
The Reference A-300 celebrates and continues the Plinius tradition of building world-class amplifiers that deliver powerful, pure sound, are built to last and look simply stunning.
The Reference A-300 is an evolution of previous models. Throughout the design process each and every part has been reviewed, evaluated and refined. Every subsection of the electronics boasts changes to components, specification, layout and interconnection resulting in a truly sophisticated amplifier.
The A-300 uses high quality, low-noise, audio grade capacitors, low-noise power components and custom high capacity power supply capacitors. Couple this with a brand new external styling that still pays homage to Plinius’ signature aesthetic and you have a true force of nature.
If you love the feeling of being immersed in music The Reference A-300 promises absolute satisfaction. Power and depth are married together with pureness and clarity.
The Reference A-300 is the pinnacle of the Plinius Range. It’s designed to take advantage of every aspect of the Reference M-10 preamplifier’s sophisticated circuitry and drive the finest high-end speakers with finesse.
Aluminium Construction
The aluminium construction provides a rigid non-magnetic housing to eliminate unwanted magnetic fields that can interfere with the sensitive audio signals.
Auricap Capacitors
Audience AV supply the Auricap XO capacitors used in key areas of the circuit. The Auricap was chosen for its superior clarity and dynamic ability.
Siltech Wiring
Siltech premium ‘G7’silver/gold wire provides a perfect connection between components to give clear, fast and detailed presentation of the music signal.
WBT and Neutrik Connectors
High quality WBT RCA and Neutrik XLR input connectors are fitted along with WBT output speaker terminals to ensure a low distortion interface between your cables and the amplifier.
Remote Trigger Input
When connected to a preamplifier trigger output, the amplifier will switch out of Mute and into Class A Mode ready for use when the preamplifier is taken out of standby.
Amplifier Configuration Selector (ACS) switch
The rear panel ACS switch allows for the amplifier to be configured for Stereo RCA, Bridged Mono RCA, Stereo XLR or Bridged Mono XLR modes. In Bridged Mono mode, the amplifier operates in true balanced configuration from input to output.
Ground Lift Switch
This allows for the signal ground to be isolated from the main chassis earth. This can assist in resolving unwanted ground loops or hum due to duplicate ground paths in some systems.
Ecologic Control
The amplifier can automatically switch from Class A to Class AB when unused after a listening session. This user adjustable feature is set to 30 minutes during manufacture and can also be switched off entirely.
Class A/Class AB operation
In Class A distortion is minimised for ultimate sonic performance. In Class AB, performance is still exceptional but power consumption and heat output are reduced.
