The HD-800s replaced my recently purchased Denon AH-D7000s at my office desk. The Sennheisers were powered by the excellent Headroom Ultra Desktop amplifier with onboard 24 bit- 96 kHz DAC. This amp was discussed in a previous review here, and is a perfect match to these or any other high end headphone. The adjustable preamp gain switch made it easy to get the volume pot into the middle of its range, even with headphone impedances that varied by a factor of more than 10. The amp was fed by a M-Audio Audiophile 2496 soundcard from my office PC. Playback was via Foobar2000 using the ASIO output module to the M-Audio ASIO compatible driver. Source files were lossless Apple Lossless Codec (ALC) or Free Lossless Audio Codec (FLAC) files at either 16 bit 44.1 kHz or 24 bit, 96 kHz. See the Denon/Headroom review for a more in-depth discussion of this computer audio setup. As with the Denons, I played music through the headphones over an entire weekend at moderately high volume level to break-in the driver surrounds.
