The 9000A’s discrete Class AB power amp stage delivers 100W per channel into 8 ohms (160w per channel into 4 ohms!). Unlike over-specified competitor models, the genuine 100W per channel will put the 9000A up against the best in its class. Referring to the standards set with the audiolab 6000A (rated at 50W per channel), the 9000A’s 100W per channel will undoubtedly satisfy the most demanding of loudspeakers and their power-hungry masters.

A key to the audiolab performance is the world-famous CFB (Complementary Feedback) topology, which ensures superior linearity and excellent thermal stability, as the idle current is kept independent of the temperature of the output transistors. An all-new and custom specified 320VA toroidal transformer, followed by 4 x 15,000uF reservoir capacity (60,000uF in total), helps the amp to maintain firm control of the music whilst enabling excellent dynamic range.

In an effort to maintain consistent signal purity, with line input signals passing to a precision analogue volume stage, the preamp section is kept as simple as possible. As with all of Jan Ertner’s designs, the circuity is a work of art in more than layout and architecture. The very design protects the sensitive preamp section from noise interference and colouration – a key cornerstone of the audiolab philosophy.

The 9000A features the latest ESS 9038PRO flagship 32-bit DAC chip. Using the critically acclaimed patented HyperStream® II architecture and Time Domain Jitter Eliminator, the ES9038PRO delivers an unprecedented performance level that will satisfy the needs of the most demanding audio applications – fitting an amplifier of the 9000A’s calibre.

Years of experience and countless ESS-equipped models mean that audiolab is more than familiar with making the most of this technically excellent but challenging DAC technology. Great attention has been paid in developing a system that allows audiolab electronics and ESS DAC technology to offer the best in audiophile performance.

The amp’s four S/PDIF digital inputs – two coaxial and two optical – handle hi-res PCM data up to 24-bit/192kHz and benefit from a host of user-selectable digital filters that allow the user to optimise the response to suit the source file and bandwidth of the partnering equipment.

PCM audio is supported to 32-bit/768kHz, alongside DSD to 22.5MHz (DSD512). Every significant hi-res and lossless audio format is catered for, including FLAC, ALAC, AIFF and WAV, as well as compressed legacy formats.
