The desk moving suggestion is good idea “kilil”. That indeed would provide the best of both worlds. I hope it may work in Evan’s case.
In fact, why not move the desk, dispense with the sofa, buy an extremely comfy desk chair and be done with. If a 2nd. listener’s spot was needed it could be in another moveable chair behind the main desk one. A sofa/off-the-sweet-spot listening position has never been to my liking.
Or, perhaps this desk/no sofa idea may work better if the speakers were placed on the desk’s wall as opposed to in front of the windows. If 90% of the listening time will be done from the desk, why not have SoundLab desk speakers!??
