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

Brilliance Evolved
The 8300As 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 dened, their character is vividly portrayed. Dynamic range is greater and frequency response is further extended, with greater bass denition 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 reective of the source material.

Classic Hi-Fi For the Modern Age
To incorporate all this functionality, there must be compromise under the lid, right? Wrong. The
6000As lead electronics designer is Jan Ertner the same man responsible for the 8300A, as well as
many other award-winning audio components over the years. When challenged to deliver 6000A at
such a low price point, Jan returned to the technologies he implemented in the 8300A and
painstakingly redeveloped them, whilst adding high-quality digital circuitry to the mix. The result is a
new-generation amplifier evolved from the architecture of its pricier sibling, delivering exceptional
sound quality alongside those flexible facilities.

Versatile High End Integrated Amplifier
At this ampliers heart is a powerful dual-mono amplier delivering 75W per channel into eight ohms. CFB or Complementary Feedback topology oers superior linearity and ensures excellent thermal stability.

ACD or Active Current Drive means current limiting is under microprocessor control, programmed to allow the amplier to supply high currents into complex loads, on par with ampliers that are bigger and more powerful on paper.
