Key Features
The Audiolab 6000A Stereo Amp & Concept 40 Speakers, HiFi Package is an all-in-one solution with what you need to get you started on your hi-fi journey with an amplifier, speakers, and cables all included. Q Acoustics' flagship floorstander, the Concept 40 loudspeaker has once again covered new ground in performance capabilities. Their 'Russian Doll' philosophy - the speaker within a speaker technology - works supremely well at obliterating resonance leaving an audio performance that's unmistakable.
The 6000A is the latest in a long time of Audiolab integrated Amplifiers with a pedigree that stretches back to the very first 8000A that made Audiolab an overnight sensation. An amplifier remains the beating heart of any high-performance audio system, but 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, and amplification for headphones and 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 Fisual / QED Hi-Fi Cable Pack is also included to get you up and running straight away.

"These floorstanders have quality from their deep-gloss finish to the elegantly machined aluminium faceplate. The Concept 40s aren’t fussy about partnering equipment, detail is good and there’s consistency to the way these speakers deliver all parts of the frequency spectrum. With better refinement, a smoother delivery and easy-going balance, they deserve serious consideration."
"Building on the success of the concept 20s, the floor-standing 40s use the same Gelcore construction to deliver a wonderfully transparent and enjoyable sound that is better than speakers costing considerably more"
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.
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.
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.
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.
Q Acoustics have achieved a level of performance that would normally be out of many Hi-Fi fans' reach with the Concept 40 floorstanding loudspeakers. Their innovative Gelcore™ construction method has been the driving force behind the Concept's remarkably impressive detail which will leave you both smitten with the sound and pleasantly astonished at how much they cost.
Two powerful magnets in each speaker behind the bass woofers offer a wide dynamic range with lush soundtracks sounding even bigger through the Concept 40's. Constructed to suit a more spacious listening environment, the Gelcore™ 'sandwich' technology - a pair of MDF sheets bound together by the acoustic enhancing Gelcore™ material - perform a brilliant job of keeping vibrations under firm control. It's this type of thought process and low-cost way of tackling the resonance problem which keep the Concept 40 speakers a sensible price point with a musicality that's normally reserved for speakers two and three times their price setting a new standard in audio achievement.
The Concept 40's also come with an improved soft dome tweeter design by being decoupled from the aluminium front panel to prevent vibrations tarring those sweet high-end frequencies. An improved cross brace structure and an elegant tripod base platform also contribute to keeping these refined speakers perfectly rigid. Even the plush looking cable terminal posts have an effervescent quality about them which any audiophile would appreciate.
