Audio Analogue "Absolute PA" stereo power amplifier

Pure Class A Power Amplifier

Derived from the ABsolute integrated amplifier, ABsolute PA is a 50W stereo amplifier capable of driving a wide variety of speakers while maintaining the refinement that distinguishes Class A.

All the warmth and musicality of pure Class A in a reference amplifier that can express itself at its best in combination with the ABsolute Preamplifier.

Key Features

• Pure Class A operation – delivers 50W into 8Ω with the warmth and refinement of Class A.
• Fully dual-mono construction – independent power supplies maximise channel separation.
• Zero global feedback circuit – preserves natural musical reproduction.
• Fully balanced architecture – reduces noise and improves signal integrity.
• Enhanced SeGeSTA amplification stage – Airtech's asymmetrical current-mode design with no global feedback.
• Oversized military-grade resistors – minimise thermal distortion.
• 7N OCC solid copper internal wiring – ensures outstanding signal transmission.
• Audiograde capacitors – selected for optimum sonic performance.
• Microcontroller management – reliable and stable operation.
• Available in natural aluminium or satin black finishes.

Technical Description

Fully dual-mono configuration starting from dual power supply.

Circuit without global feedback.

All stages are fully balanced.

ABsolute PA is polarized in Class A up to 50W at 8 Ohms.

The amplification stage is a further improvement of the SeGeSTA structure already used in the Anniversary series. The structure is deliberately asymmetrical and operates in current, with no global feedback.

Large use of oversized military resistors to minimize thermal distortion. Internal wiring with pure solid copper 7N OCC conductors, gold-plated copper output connectors, audiograde capacitors and microcontroller management.
