Marantz is hoping to change that with the ZR6001SP. The installation-free, distributed audio system is a two-part affair consisting of a ZR6001 A/V receiver and a ZC4001 audio client, the latter of which looks like a tabletop radio with built-in stereo speakers. Eschewing complicated networking solutions--and the need for professional installers--the ZR6001SP uses a technology called Digital Audio via Electrical Distribution (DAVED) which uses the AC wiring in your home to transmit audio signals from the ZR6001 receiver to the ZC4001 client.
