Chord CPM 2800 MKII amplifier to feature Hugo FPGA DAC tech

  • If you were thinking of adding a Chord Hugo, or the recently released Hugo TT, to your existing amplifier you might want pause for a moment. The Kent-based audio electronics firm has dropped a Friday 13th shock-surprise into our laps: in bringing their CPM 2800 digital integrated amplifier to second generation status they’ve only gone and dropped the Hugo’s FPGA D/A conversion technology – complete with Rob Watts’ custom code – right into the amplifier’s pre-stage.

    Not only does this (likely) add the Hugo’s terrific handling of transparency and delicacy (see my review here) to the CPM 2800 MKII but it brings the portable’s connectivity along for the ride; aptX Bluetooth for wireless streaming and a second USB ports for hard-wiring of Android and iOS devices. Unlike the Hugo, the CPM 2800 MKII’s USB inputs are galvanically isolated.

    At the business end of the amplifier sits Chord’s “award winning proprietary ultra-high frequency power supply” that promises 120 wpc and 170 wpc into 8 and 4 Ohms respectively.

    Heavy duty gold-plated binding posts, HT bypass, a display panel that can be read from the listening position and remote control round out this integrated’s feature set. Oh, it’s built like a tank too.

    The CPM 2800 MKII will sell for £6690 and gets its first taste of daylight at the 2015 Bristol Sound and Vision show next weekend (20th – 22nd February).
