I bought a Denon ADV-M71 unit in Nov 03. The first unit broke down after 4 months and was away for repair for the best part of 5 months while Denon unsuccessfully tried to get the right part. After an age I got Superfi to agree to give me another unit - Hurrah, I thought. Not so, within 5 months this unit has packed in and is about to sail off into the ether back to Denon. Gulp ! Has anyone else had problems with this machine ?
