HDV820 By Sennheiser Announced - New Amplifier

Sennheiser have announced their successor to the HDVD800 with the launch of the HDV820 digital amplifier. It was 2013 when Sennheiser first launched their HDVA600 analogue and HDVD800 digital headphone amplifier to pair with their HD800, HD700 and HD6xx range of headphones. They were incredible feats of engineering and the sound was amazing from both of the units. Wind on 4 years and Sennheiser are now replacing their much loved HDVD800 with the brand new HDV820 digital amplifier.

Choosing to stick with the amazing and highly regarding ESS brand of DAC chipsets Sennheiser have chosen to up the anti and selected the DAC capable of receiving data from any source outputting up to 12.3MHz. The previous HDVD800 was capped to 24/192 so this will be a big step up.

A bold move has also been taken by Sennheiser with their range of outputs levied on this new amplifier. With a breadth of audio outputs that include XLR3, XLR4, 6.3 mm- and a 4.4 mm Pentaconn socket, it is easy to find the optimal way to connect your headphones with the HDV 820. It performs brilliantly with digital sources, whether optically via coax or via USB, and features balanced (XLR) and unbalanced (RCA) analogue inputs.

We are keeping an eye out at this years Munich High-End show in May as we will then have further details in relation to price. I speculate that it will be around the £1500 - £1600 mark and release date is still to be announced.

Chord Hugo 2 Announced

Alongside Poly the Chord Hugo 2 was also officially unveiled at CES 2017. The new Hugo 2 features the latest WTA filters, better performance. This new breed of Hugo kicks off from where the original outstanding Hugo was. Increased performance and new filters take the Hugo series up another notch.

The Hugo 2 has been dramatically redesigned with all-new casework, flexible new features, plus next-generation technical and sonic performance at £1,800. Chord have announced both the Hugo 2 Silver and Hugo 2 Black

The precision-machined aircraft-grade aluminium case has a sharper, lower profile design than the original Hugo and four spherical control buttons. The spheres, which are top-mounted, allow for future expansion side-modules. The top-mounted volume-control sphere that was found on the original Hugo has been retained and made larger for more intuitive operation.

The stylish new design and additional functionality has further made the Hugo a device for both indoor and outdoor usage and with the inclusion of a full-function remote control adds further flexibility and the practical line-level output mode of the original has also been retained.

New levels of technical performance

All areas of the original Hugo have been improved upon with performance gains having been made in timing accuracy, noise reduction, headphone amp power and dynamic range. Chord Hugo 2 DAC / Headphone Amp

Four digital inputs

Akin to Hugo the Hugo 2 offers four digital inputs (optical, coaxial and HD USB) plus extended-range Bluetooth, with high-resolution file playback up to 768kHz and up to DSD512 (Octa DSD), via its HD USB input. Analogue outputs include 2x RCA, plus 3.5mm and 6.35mm headphone outputs.

User-selectable filtering option

A new addition comes in the form of four-function switch filter, operated by its own control sphere. This offers the user a useful degree of user-selectable frequency-shaping, bringing warm and soft or transparent and incisive presentations, giving additional flexibility and user control.

Battery life improved

Battery playing time has increased to c.14 hours and USB fast charging over micro has been included: fast (1.8 amperes) and slow (less than one ampere). An indicator shows charging and battery-charge status.

Lower distortion, better output stage

To further improve of the output stage and reduce distortion even more brand new digital DC servos have replaced the inline capacitors which helps power-drive performance and capability of the output stage.
