Officially, the HDV 820 is slated to release July, with more details to come. We were showcasing two of them at the Munich High End show, connected to a T+A Turntable (thanks guys!) spinning the ever famous Pink Floyd "Dark Side of the Moon" vinyl, and an Apple MacBook Pro via USB streaming TIDAL through the Audirvana player. With the new balanced 4.4mm Pentaconn outputs nicely volume matched to the 4-Pin Balanced XLR output, attendees were having fun swapping the HD 800S and HD800 with each other and remarked to us how great the synergy was between the gear. That was the design goal, but it was nice to hear it from the enthusiasts! Many people were also curious about the connection options around back, including the USB-B, Toslink Optical, coaxial, balanced and unbalanced inputs, and the balanced dual 3-pin for variable (volume adjustable) preamp output integration with your speaker system. Some interesting tidbits: unlike most amplifiers, the HDV 820 was able to connect both balanced and unbalanced safely at the same time, also the amplifier uses a zero-negative-feedback, current amplification design, which makes a significant impact on headphone impedance response and goes a long way towards explaining why the resulting sound is so pure and engaging. "Dark Side Of The Moon" had a very "punchy" impact and believably realistic performance despite the trade show's ambient noise, the effect was like starring in a movie scene with "Time" or "Any Colour You Like" as the soundtrack overlaying everything going on. The HDVD 800 will continue to be sold alongside the HDV 820.
