When listening to music I also remove the backrest cushions.
Well, it doesn’t revolutionise my sound quality, but it DOES improve my right field imaging. I did find it irritating that I could here a mass of detail in the left field that was somewhat muted in the right …no longer!
I have seen a number of system photos over the years where a sofa impinges in either the left or right speakers, so I hope this might act as seed corn for a return to Victorian/Edwardian furniture styles!
Do you not have a position between the speakers to listen?
I have a dedicated listening room, but my wife and I plan to relocate the hifi to the larger living room, but when we do the sofa will be arranged (by mutual agreement) in the prime listening position for best soundstage, response, etc.
I’m always so surprised that there is currently so few options for siting speakers close to a wall considering most of our domestic restrictions. One of my stronger aural memories is my surprise at how the SL2s that Alastair and Andy from Signals brought just clicked the music in my room compared to my in space Spendors and the Focal and Kudos that they had also brought.
