Product Description

Sennheiser HDVD800  was built to sound just as brilliant, crystal clear and distortion free as sitting right in front of the audio source. Creating a level of acoustics that surpasses everything before it was the vision for this audiophile headphone amplifier.

A fitting partner for Sennheiser HD650/700/800 or other fine headphones. Unlike Sennheiser HDVA600, HDVD800 includes a high quality DAC and sounds even better.

Great Design

Sennheiser's first amplifier for dynamic headphones, the digital HDVD800 has a fully symmetrical layout for analogue audio sources ensuring absolutely symmetrical signal transmission from source to headphones. It is equipped with a high-quality Burr-Brown DAC that converts digital audio to analogue signals up to 24bit/192kHz.

This enables transmission of the entire frequency spectrum of high-end audio sources without any loss of frequencies. A glass panel embedded in the aluminium housing of the amplifier gives a clear view of the top-quality interior of the HDVD 800. Selected components and sophisticated circuitry promise the ultimate in listening pleasure.

Dynamic Range

In order to fully exploit the sound potential of the HDVD 800 with any audio source, a rotary gain switch at the rear of the unit provides simple adaptation of the amplifier output to the audio input voltage. This ensures that the dynamic range can be used to its full extent.

The rotary potentiometer is mechanically connected to the volume control by an unusually long 150mm shaft which allows the signal path between the audio source and the potentiometer to be kept very short preventing possible interference of the signal.

High-quality components (Alps RK 27 quad) ensure that the volume is controlled with maximum precision and a fine rotary ‘feel’. Also visible through the glass panel are the cooling element, the audio relay and countless MELF resistors for the amplifier.


Specially made cables for symmetrical connection are supplied and normal 6.3mm jack plug connection is supported too. HDVD800 has an asymmetrical input where incoming signals are symmetrised before further processing. Digital sources are connected to the unit's rear via AES/EBU, S/PDIF (optical and coaxial) or USB (2.0 offering up to 24 bit/ 192KHz). The HDVD 800 has a balanced sound image, maximum precision and impressive spatiality.

Sound Performance

“The search for perfect sound is a constant motivation for us to develop new ideas,” says Maurice Quarré, Director Product Lifecycle Management Sennheiser Consumer Electronics. “The best example is the legendary Sennheiser Orpheus. These electrostatic headphones with a vacuum tube amplifier, which came onto the market around 20 years ago, have become an icon in the audio world. With the HDVD 800, Sennheiser is now taking up the tradition of the Orpheus, providing music lovers with the perfect combination of Sennheiser headphones and a specially matched amplifier.”

Beautiful Casing

And such meticulous attention has also been applied to the exterior. Both the housing and the potentiometer control as well as the rotary switch for selecting the source are made of anodised aluminium, while the front panel of the housing and the controls are milled from solid material. This makes the HDVD 800 as much of a joy to use as it is to listen to. This headphone amplifier is indeed a new high end benchmark in headphones listening.

    I was sceptical when this came out. Already using a Graham Slee Solo Intro, how much better could this be and was it really worth £1499. Was it just marketing hype? Having seen it on several newsletters and been tempted many times, I made a trip to Audio Affair for a listen and took my well used Solo for comparison. Initially I wasn't blown away. There was certainly an improvement, but it wasn't a night and day change in sound. However after listening for a solid two hours and countless times switching back and forth (and also throwing an Audiolab MDAC and Sugden HA4 into the mix just for comparison), it became clear over the duration of my visit that what this gets out of the HD800 was nothing short of remarkable. The tonality to the bells on Pink Floyd's Money and the punch with which this delivers every note was way ahead of the Solo, which simply sounded flat and slow by comparison (and the HA4 while good couldnt match it). Switch over to some Cat Stevens (most of which isnt perfectly recorded but I'm very familiar with) and the soundstage was so open and crisper. I've never heard Rubylove sound so fresh and live. It just sparkles. I expected to find little differences between this and the Solo, but the longer I listened, and the more I switched back and forth, it became clear that the HD800s only really come alive with this matching amplifier and Sennheiser have done very well to match them up so well together. I couldn't resist buying one and on reflect, its been one of the best investments in listening I've made.
