In 1983 audiolab unleashed the iconic 8000 Series, taking the British hi-fi scene by storm and cementing its reputation as one of the most significate hi-fi products of its time.

25 years on….


Audiolab is set to repeat this feat with the all-new Audiolab 6000A Integrated Amplifier, ideal for modern music lovers seeking premium-level performance, build quality and facilities at an affordable price.

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.

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 amplifiers.

Testimonials

Bought some Rega Kyte speakers, stands and chords from DB online and they were incredibly helpful. They updated my delivery address very quickly and recommended a longer cut of cables which they did complimentary. They also noticed I didn’t order with banana plugs so called me back to double check, which I did mean to order. When i had some issues connecting my cables and speakers, I called for some advice which they happily gave. Excellent service and next day delivery to London. Thoroughly recommend.

Probably one of the best companies in the world. They had to special order in the speakers which took a fair bit of time, which is totally understandable, but they kept in touch with me throughout the entire time with updates (even on a Sunday!!!) and once the speakers were with them, they were dispatched and arrived next day.

The entire sound system that I purchased is insanely good, but still not as good as Doug Brady HiFi!

Guy H.

I have recently purchased a HiFi package with Doug Brady and I could not be more thrilled with my experience with them.
When I walked into the store, I was made to feel welcome and was introduced to some of the products. I produces a list of specific items I was interested in and John was really helpful in showing me these items. He set the system up so I could experience it, he made some suggestions which made the package even better. Nothing seemed too much trouble for him, he was very knowledgeable about the products and gave great advice. I didn't feel pressured to buy anything, or didn't feel that he was upselling at any point. I left with an amazing package and I'd like to thank John and the team for the fantastic experience.

It’s now two weeks since I bought home my new system and I wanted to say thanks again for all your help, advice and guidance, not to mention cups of tea. I now have a system that meets all my requirements and sounds fantastic. Special thanks to Jon, who I hope is on the road to recovery from his operation and to Roger, who helped me finalise my choice. The Rega Saturn, Hegel H190V and Dali Rubicon 2 is undoubtedly the best system I have ever owned.
