Audiolab 6000A Stereo Integrated Amplifier DAC

Description: Audiolab 6000A Stereo Integrated Amplifier DAC - Black "This is a Class Leader" Outwardly, Audiolab's 6000A integrated amplifier bears strong resemblance to Audiolab's 8300A with its rotary controls and large, central OLED display. Unlike its costlier, analog-only sibling, it incorporates high-quality D/A conversion, enabling digital sources to be connected directly without an external DAC. It supplies four digital inputs, three line-level analog inputs, an input for a turntable, wireless connectivity via Bluetooth and a dedicated headphone amp, in addition to its superb performance when driving loudspeakers. In his joint review of the Audiolab 6000CDT CD transport and 6000a integrated amp for hifipig.com (which honored the combo with an Outstanding Product Award), Alan McIntosh notes, "The 6000A alone is a strong offering and I suspect as more people hear it the market rivals will be working hard to compete, as a combo for me this is a class leader and is punching up the weight class in spades. Solid, punchy, refined and delivering at times a truly detailed but analogue feel, this is one to watch." Superior Digital Circuitry Much effort has been made to ensure the 6000A’s digital circuitry delivers the level of quality one might expect of a high-performance standalone DAC. As ever, Audiolab has turned to the ES9018 Sabre32 Reference chip family to perform D/A conversion, utilizing ESS Technology’s 32-bit HyperStream architecture and Time Domain Jitter Eliminator to deliver ultra-low noise and high dynamic range. No company knows more about making the most of this technically excellent, but challenging, DAC technology than Audiolab. If the circuitry that surrounds the ES9018 is not of sufficient standard, the resulting sound can seem a little cold and hard. Treat it right, however, and the level of musical expression that this chip digs from the digital signal is captivating. Audiolab’s original, universally acclaimed M-DAC was one of the first home audio components to incorporate an ES9018 chip back in 2011, and the company has been honing its implementation ever since. Amazing Analog Section The 6000A’s discrete Class AB power amp stage delivers 50W per channel into eight ohms, with a maximum current delivery of 9 amps into difficult loads. The output stage of the discrete power amp circuits uses a CFB (Complementary Feedback) topology, ensuring superior linearity and excellent thermal stability, as the idle current is kept independent of the temperature of the output transistors. A substantial 200VA toroidal transformer, followed by 4x15000uF reservoir capacity (60000uF in total), helps the amp to maintain firm control of the music while enabling excellent dynamic range. The preamp section is kept as simple as possible to maintain signal purity, with line input signals passing to a precision analog volume stage. The latter covers the range from -80dB to +8dB in steps of 2dB and 1dB (step resolution increases with volume position). Much effort has gone into the physical layout of the 6000A’s circuitry, protecting the sensitive preamp section from noise interference. This, plus the use of independent low-noise power supplies for critical stages, helps to deliver a performance that rivals significantly more expensive analogue amplifiers, even before taking the 6000A’s impressive digital circuitry into account. MM Phono Stage and Dedicated Headphone Stage In recognition of the recent vinyl revival, Audiolab has included a phono stage for moving magnet phono cartridges – a high-quality, low-noise, JFET-based circuit with precise RIAA equalization. Similarly, an increasing number of people are using headphones for music listening, so Audiolab has incorporated a dedicated headphone amp with current-feedback circuitry. Its gain bandwidth and high slew rate ensure a dynamic, detailed and engaging performance with all manner of headphone types.
