The Sooloos audio-server system from Meridian is an audiophile favorite, but the Control 15 with touchscreen interface is pretty expensive at $7500. New at CES is the Media Core 200 server, which uses the iPad or iPhone as the control interface and sells for $4000. That's still a lot, but it includes 500GB of hard-disk space—enough for 1000 uncompressed CDs—and access to Rhapsody and Internet radio. Outputs include S/PDIF, SpeakerLink for Meridian digital powered speakers, and fixed and variable analog.
