An amplifier remains the beating heart of any
high-performance audio system, but in 2018 a truly versatile integrated amp
needs to cover many bases – digital and analogue sources, wireless connectivity
for portable devices, a phono stage to cater for vinyl playback, amplification
for headphones as well as speakers… That’s a lot to pack in, whilst keeping
performance high and the price tag affordable – and yet, that’s exactly what
the 6000A delivers.

The sound of science

Outwardly, the 6000A bears strong resemblance to the 8300A
with its rotary controls and large, central OLED display. Unlike its costlier,
analogue-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 analogue inputs, an input for a
turntable, wireless connectivity via Bluetooth and a dedicated headphone amp,
in addition to its ability when driving loudspeakers.


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, utilising 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.

Analogue circuitry

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.

The preamp section is kept as simple as possible to maintain
signal purity, with line input signals passing to a precision analogue 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.

Turntables and headphones

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 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. Its gain bandwidth and high slew
rate ensure a dynamic, detailed and engaging performance with all manner of
headphone types – more boxes ticked for this most integrated of integrated
