Ok, this newbie has learned to stay away from Bose. I'm now comparing two all-in-one systems, each with five-disc CD changer. Yamaha about $100 more than Sony. Systems are the Sony DAV-C700 and the Yamaha YHT-34. I've read the CNET review of the Sony (good price but less than par sound) but haven't heard anything about the Yamaha. Any thoughts? David My thanks and appreciation ahead of time.
