A1008 Integrated Amplifier
The A1008 employs exactly the same circuit elements and conceptual physical layout as the kW550. The overall sound quality is, apart from 3dB less headroom, indistinguishable from the kW550.
Additionally the A1008 has a full range of digital (including USB) inputs with a superlative quality DAC included. The A1008 is a cutting-edge sophisticated amplifier which gives superlative performance from almost any signal source into virtually any loudspeaker. In every way it is a worthy successor to its great great grandfather the A1000. But in addition it has much more power and a full range of up-to-date digital inputs.
