Overview & Features


The 8300MB is a pocket powerhouse, housing 250W of pure, balanced amplification. 8300MB’s full power output is delivered into any loudspeaker load – unconditionally. Massive reserves of power are available for high current drive capability to power and control the mightiest of speakers.This latest development of the Audiolab range now features a fully balanced power stage making the most of the balanced XLR inputs. This makes 8300MB a perfect match for the M-DAC using its balanced outputs, even over long cables.

Brilliance evolved

Audiolab’s new 8300 Series has big shoes to fill. After all, the preceding product generation has won more awards in the UK press during the last five years than any other range of high-performance audio electronics.

New Updated Aesthetic

The newly updated external structure of the 8300 series follows the new design aesthetic of Audiolab products going forward, incorporating softened lines and textures yet still maintaining Audiolab’s instantly recognisable and contemporary style.

The 8300 series’ blasted aluminium finish, CNC routed aluminium dials and display certainly look cutting-edge, yet with every Audiolab product, form follows function. The new display and controls enable a fast and intuitive access through the vast routing options and filter settings in both the A and CD.

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.
