Audiolab 6000A Integrated Amplifier
The elegant slim casework with clear OLED display and large rotary controls in common with the more expensive 8300A means you cannot mistake the 6000A for anything other than 100% Audiolab even at first glance.
However unlike the analogue only big brother the 6000A features four digital inputs as well as three line-level analogue inputs, an input for a turntable, wireless connectivity via Bluetooth and a dedicated headphone amp!
Audiolab has turned to the ES9018 Sabre32 Reference chip family to perform D/A conversion, utilising ESS Technology’s 32-bit HyperStream architecture and Time Domain Jitter Eliminator to deliver ultra-low noise and high dynamic range.
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 whilst enabling excellent dynamic range.Audiolab has included a phono stage for moving magnet phono cartridges – a high-quality, low-noise, JFET-based circuit with precise RIAA equalisation. Similarly, an increasing number of people are using headphones for music listening, so Audiolab has incorporated a dedicated headphone amp with current-feedback circuitry.
The 6000A amplifier is available in both black and silver finishes and comes with a thoughfully laid out remote control as well.
