Thank you for your reply. It sound absolutely spectacular. It is educational to follow your changes. If you have time I love to see new photos.
Are you saying you are using full CA 840 system (pre/power/cd) for music and adding the NAD M3 for your rears (or visa versa)? Isn't this over kill? Have you considered an amp w/ HT pass thru so you can add addition channels for movies?
