During the half-hour Julia and I spent visiting Channel D Software's Rob Robinson, the room never ceased to be mobbed with attendees. That was partly due to the good sound (provided by Joseph Audio Pulsar speakers, Hegel H20 amp, Artemis record player with Zu cartridge, and Audio Research DAC8—plus, of course, a Synology NAS and a brace of Apple computer gear, driven by Channel D software), and partly to the fact that the exhibit was like a free seminar on both the basics and the minutiae of computer audio, with Robinson as the generous instructor. Channel D's Pure Music 1.8 ($129) is now available, and I hope to try it soon after returning home.
