Expert 1000 Pro Dual


The major innovations of the Original d'Atelier exclusive edition enabled Devialet engineers to push a step further the frontiers of extreme audiophile performance. This limited edition now paves the way to the new Expert Pro line, with Expert 1000 Pro as the most powerful incarnation.

With 5 new patents, a power output of 1000 Watts and unprecedented performance, an audiophile icon is born. The measured amplification performance of the 1000 Pro is now best-in-class at all power levels.

The 1000 Pro features a host of upgrades from the 800 including a new version of the ADH Intelligence® system. Each element of the ADH core has been carefully rethought in order to design the most advanced version of ADH, which provides significant performance improvements at all power levels. The THD is then reduced at lower levels. 

The sense of the Class A amplifier has been improved from 8 bits to 10 bits (or 1024 levels instead of 256), multiplying the precision of the ADH core's control by 4. In addition, thanks to a new and more performant control algorithm, the regulation of the ADH loop is even more responsive. 

The amplifiers have been improved with a new Class A amplifier reducing harmonic distortion rate and power consumption and an advanced Class D amplifier inducing a power transmission improved by 25%. Zero current goes through the Class A in standby mode for causing minimal power consumption.

Other innovations include a new power supply to handle transient loads twice as fast. which can, in addition to reaching 4000w of peak power (formally 3000w), improve the local decoupling from the mains network by 15dB. There is a new thermal management which can dissipate heat twice as fast and a new architecture allowing integration of future hardware and software evolutions. This allows for better performances during longer listening sessions at high power levels.

Thanks to its unique architecture, Expert 1000 Pro is capable of integrating hardware and software innovations that will be introduced by Devialet engineers in the future.

There is an upgrade scheme available for anyone looking to upgrade from their Le 800 to the Le 1000 Pro.

The 1000 Pro is available to pre-order now from our London store. Get in contact to arrange a demonstration.
