Audiolab 8300A ολοκληρωμένος ενισχυτής

Ολοκληρωμένος ενισχυτής
Πλήρως επανασχεδιασμένος από την αρχή, ο νέος μας ολοκληρωμένος ενισχυτής, ο Audiolab 8300A είναι μίλια μπροστά από αυτό που ήταν ήδη, πρωτοπόρος στον κλάδο. Μεγαλύτερη ισχύς – 75 w @ 8ohm/115 w @4ohm per channel, πρόσθετη είσοδος phono MM/MC, 2 xlr inputs και νέο styling σημαίνει ότι ο ενισχυτής είναι πιο κομψός και πιο ευέλικτος από ποτέ. Το πιο σημαντικό είναι ότι τα νέα, εξαιρετικά αποδοτικά κυκλώματα και τα βελτιωμένα εξαρτήματα δημιουργούν μια εμπειρία ακρόασης που φέρνει νέο ορισμό στην αγαπημένη σας μουσική.

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 – 75 w @ 8ohm/115w @4ohm per channel, phono MM/MC, 2 xlr inputs 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.

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.

Classic Hi-Fi For the Modern Age
To incorporate all this functionality, there must be compromise under the lid, right? Wrong. The 6000A’s 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 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.
