It is a lovely room but that sofa between the speakers? Also that glass-fronted cabinet on the left hand side seems to be bang on first reflection point?

I try not to get obsessed about this stuff, it doesn't do anything for being able to relax and enjoy music, and it probably doesn't have too much of a bad effect on the sound quality, but I would have to move that sofa. And move the turntable out of the corner too.
