This headphone amp and DAC by any measure is excellent. It pairs extremely well with the HD800S to the point where it feels like a miniature HD1 Orpheus rig. It keeps the analytical flatness of the HD800 true while allowing you to use the optional balanced cable for those headphones which is a true treat to the ears. With my Audeze LCD-4z headphones it powers them perfectly and provides a great user platform to run multiple headphones out of a single source. My only complaint is that there is only one unbalanced output but two in the rare 4.4mm plug developed recently by Sony. Overall it's an excellent desktop amp that would serve anyone well if they aren't disgusted by the extremely high price.
Pros: Great sound 4 balanced outs at once are possible Very easy to use and set up
Cons: Pricey Large Only one unbalanced output

The Sennheiser HDV 820 is a beautiful piece of audio gear. It's The finest headphone amp I have ever had the pleasure of owning. I'm using the it to drive my matching Sennheiser HD 800S headphones, and it's a powerful match. The sound is stunning. I have the amp sourced with my NAD 568 CD player Connected via coax cable to take advantage of the fantastic DAC built into the Sennheiser amp. I would highly recommend the HDV 820 to anyone who is looking to put togeather a state of the art headphone rig.
Pros: Superb sound, flexible connections and first class build quality.
Cons: None, but I wish it came with a remote control.
