Thanks for all the advice,
the room is carpeted and fairly heavily furnished with material roll down blinds covering all windows. Just directing the speakers slightly away from me has made a considerable difference, I'll stick with the Arcam for now although it was a good excuse to get a Dolby atmos receiver😉.
one final question, I currently have a rp110 sub does anyone believe it would be worth adding another 10" sub for HT or eventually just replace it with a larger one. My room is about 23sq metres or around 245 sq ft.
