The 8300 MB is a pocket-sized powerhouse, housing 250 W of pure, balanced amplification. Full power output of 8300MB is delivered in any speaker load - unconditionally. Huge power reserves are available to drive high current power and control the most powerful of loudspeakers. This latest development in the audiolab range now features a fully balanced power stage, taking full advantage of the balanced XLR inputs. This makes 8300MB a perfect match for the M-DAC using its balanced outputs, even on long cable runs.
Technology
Pure power
The 8300MB is possibly the perfect example of audiolab's goal of effortlessly reproducing music in exquisite detail. The 8300 MB is not only 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 8300 MB is arranged as two complete power amplifiers that are bridged to the speaker terminals. Each power amplification stage is fed by one of the balanced input terminals, so the 8300MB operates as a fully balanced amplifier direct to the speaker output.
Technology
Pure power
The benefits are a high level of noise rejection and lower transient distortion, plus the amplifier's ability to draw maximum current from the power supply as needed to follow the musical waveform accurately.
It all adds up to a surprisingly vivid and highly impactful musical performance that will put more energy into your speakers and also control them like never before.
