Here are some pics of my room after repositioning. There's probably one too many armchairs, but the room serves multiple uses.

You'll notice two NAD amps in the rack. The lower one is an older purely analogue 7000 that I use for phono playback. Upper amp is C390DD which has no analogue inputs as configured. At the moment I change banana plugs to the Axioms depending on source.

Thanks to all for advice, with special thanks to Mojo for the suggestion to put speakers along long wall.

P.S. I never had a lava lamp in the 60's-70's ... call it a post mid-life moment.
