audiolab 8300A dual-mono integrated amplifier with balanced input and MM/MC phono stage
Completely redesigned from scratch, our new integrated amplifier, the 8300A is miles ahead of what was already an industry-leader. Higher power, an additional phono stage and new audiolab styling means the amplifier is more stylish and more versatile than ever. Most importantly, its new, ultra-efficient circuitry and streamlined components create a listening experience which brings new definition to your favorite music.
Overview: Brilliance evolved
The 8300A’s circuit design delivers all-new sound quality. The soundstage it produces is deeper and broader, with greater space and separation within. Instrument and voices are better defined, their character is vividly portrayed. Dynamic range is greater and frequency response is further extended, with greater bass definition and treble that is both crisper and sweeter. In short, it delivers an open window on the music being played, as all great HiFi should, engaging the listener with natural, unforced energy that is fully reflective of the source material.
Overview: Versatile High End Integrated Amplifier
At this amplifier’s heart is a powerful dual-mono amplifier delivering 75W per channel into eight ohms. CFB or ‘Complementary Feedback’ topology offers superior linearity and ensures excellent thermal stability.
ACD or ‘Active Current Drive’ means current limiting is under microprocessor control, programmed to allow the amplifier to supply high currents into complex loads, on par with amplifiers that are bigger and more powerful on paper.
