Thanks that makes me less tempted to go out and buy some bipole speakers and start chiseling holes in the wall. I was hoping one of the answers wouldn’t be moving house haha.
Thanks, I’ll keep experimenting. I’m trying different positions further out along the wall per suggestions plus re-doing the calibration for ‘wide imaging’.
Obviously the speaker position / Hi Fi generally was only one of the reasons for moving. Priorities in everything!
Thanks all, now sorted, the Naim forum hive mind came through again!
The solution was:
- Move the speakers back further out (but not quite as far as I originally had them right in the corners).
- Using the newest version of Dirac to run a ‘wide image’ calibration using seventeen points covering a cuboid of measurement positions around the couch in addition to the central listening position.
I don’t know if this helped with the imaging but this certainly made everything sound better - during my Dirac research I learnt about Schroeder frequency to appropriately set the “target curtains” mentioned by @Edmund-of-Essex; the upper limit around 500hz and the lower limit set at per stated frequency range for the relevant speaker. This addressed the node/anti-node interference in the room but without changing the voice of the speakers. Really noticeable when watching the intro to Bosch - the symbols almost completely disappeared with my original Dirac calibration applied to 20hz - 20khz - now they are back and everything sounds more natural.

Hi Chaff,
Great result! Thanks for the update on your success.
I also think the older ARCAM AV receivers and processors (I.e 800 series) are a better value proposition than the latest ARCAM models with the current DIRAC license offerings. Only my opinion of course, and there are plenty of excellent AV equipment choices from other manufacturers.
