8300A
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.
Amplification Redefined
While striving to achieve the most supreme sound quality, each stage of Audiolab product development is focused on usability. In particular with the 8300A, ensuring simple yet in-depth control, veteran amp designer, Jan Ertner build the amplifier functionality around the new display. This means users can easily find their way around the versatile configurations the amplifier offers, even while being much more advanced than its predecessors. The amplifier can behave as an integrated amplifier, power amplifier, pre-amplifier and a split pre-amplifier - easily paired with a multitude of hi-fi systems.
The 8300A works as coherently inside as it does on the outside - By taking a completely new approach to the layout, a dual mono structure means inter-channel interference is minimised. Crucial components processing audio and the power supply are completely separated as far as possible.
Our new technology - Active Current Delivery also ensures a completely clean sound up to the point of clipping, then its advanced microprocessor limits the output, which guarantees no audible distortion, even at its louder output of 75W RMS.
Connections
On the 8300A Engineers have developed a new phono stage catering for the resurgence in vinyl records with MM and MC configurations accessible via the front panel controls. 12V remote trigger loop feature on all units so as one device is switched on, paired units are switched into or out of standby mode - working as one system for quick operation.
Wharfedale EVO 4.4
Wharfedale’s new EVO4 has grown out of the extensive research and development that produced the ELYSIAN flagship loudspeakers and borrows much of the technology involved in ELYSIAN.
The primary focus is on the AMT development resulting in a radically different way of reproducing high frequency detail efficiently and accurately. Similar cabinet technology to ELYSIAN provides a stable and solid foundation for the drive units with radiused edges to help integrate the driver output with the room acoustics. In addition the unique SLPP bass reflex system, as developed for ELYSIAN, is now incorporated in EVO4.
