The Marantz AV7005 is a fantastic preamp/processor. It provides audio decoding as well as HDMI video switching. Too many features to list, so here are links to a review as well as the spec list. This is a great piece for those whose stereo and audio/video have to share. This includes the microphone for Audyssey set up. This is part of my audio/video collection that I am selling as I downsize. I am only rating it 8/10 due to age (maybe 2 years?) - it is in outstanding condition. Make me an offer!
