Audiolab 8300A Integrated Amplifier

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 it’s new, ultra-efficient circuitry and streamlined components create a listening experience which brings new definition to your favourite music.

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.

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.
