Minimalist exterior

Exemplary build quality and reliability ensure that this is a power amp for all seasons, its versatility increased by a choice of balanced XLR and single-ended RCA inputs, bi-wire speaker terminals and a pair of 12v trigger inputs. Internal circuit components are of the highest quality, right down to the power and signal wiring, which is made of ultra-pure OCC (Ohno Continuous Cast) copper – all in aid of minimising distortion and maximising sonic clarity.

Flexibility is further enhanced by the ability to add a second 8300XP and operate in bridged mode, thus increasing the power output to 480W per channel into 8 Ohms. All audiolab amplifiers are gain-matched, ensuring perfect integration with other audiolab components.

Overview

Thrilling to listen to and uterly dependable, the 8300XP is a genuine audio thoroughbred – the perfect partner for audiolan’s 8300CD, or peerless M-DAC range.

Connectivity

The connection options on the 8300CD have been further expanded with a digital AES / EBU input and a digital XLR output. They follow the complete set of inputs / outputs from 8200CD: 2x coaxial digital input; 2x optical digital input; 1x asynchronous USB input; 1x coaxial digital output; 1x optical digital output; unbalanced RCA and balanced analog XLR outputs.

The 8300A amplifier has been developed with a new phono preamplifier for playing vinyl records in MM or MC configurations accessible via front panel controls.

12V remote start function of all connected devices. Paired devices switch together to or from standby mode.

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.]]>

Pure Power

The 8300MB is quite possibly the perfect example of audiolab’s goal to effortlessly reproduce music with exquisite detail. Not only is 8300MB an extremely powerful amplifier, offering 250W of pure power with high current drive capability, but it also features a fully balanced power stage.

Internally the 8300MB is arranged as two complete power amplifiers which are bridge coupled to the loudspeaker terminals. Each power amplification stage is fed from one of the terminals of the balanced input, therefore the 8300MB operates as a fully balanced amplifier right through to the speaker output.

Control anywhere


The 8300CD offers a digital preamp feature, with volume and source selection available on the player’s front panel and remote control. This means that the 8300CD can be connected directly to a stereo power amplifier or to a pair of monoblocks, such as the new Audiolab 8300MB, or to a traditional integrated amplifier, such as the new Audiolab 8300A.

The 8300 Series also allows control of music playback from a PC / Mac / media device via USB. When connected to a computer, the 8300CD not only identifies itself as an asynchronous DAC, but also as a HID (Human Interface Device) compatible device. This allows you to control a PC / Mac / media player without installing drivers (Play, Pause, Stop, song selection, etc.)

The benefits are a high level of noise rejection and lower transient distortion plus the ability of the amplifier to draw maximum current from the power supply as required to follow the musical waveform accurately.

It all adds up to a startlingly vivid and highly impactful musical performance that will put more energy into your loudspeakers as well as control them like never before.

When you do turn it up, expect nothing but a dynamic and punchy sound that captures all the musicality of your songs. With just 14 hand-picked components, Edge W has one of the cleanest signal paths available. It delivers our breath-taking, unadulterated British sound – nothing added, nothing taken away.]]>

Just components in the signal path.

Although minimal in its exterior design, Edge W has some complex audio engineering inside. To remove the barriers between you and your music, we have worked hard to minimise the number of components in the signal path.

As a result, Edge W delivers a more faithful reproduction of the original recording; an impressively detailed three-dimensional sound, with striking staging and focus

More musical detail.

We pioneered the use of toroidal transformers in amplifiers, which led to improved performance. In Edge we take this one step further, using opposing symmetry twin toroidal transformers. This cancels out electromagnetic interference whilst offering outstanding power and maintaining consistent tonality, no matter how loud it’s played.
