Yeah,...I've been living with the same situation of stuff in the way....in my case it's a fireplace
and speakers in CABINETS
(WAF ya know)
Was really gettin' down on my system too, especially after listenin' to one of my Grandsons' CDs which he said sounded better on the diningroom system,.....and it did
I then listened to it on earphones in the main system and the missing stuff was back!! So I listened near-field on the M50s and it was there, but nothing spectatular.
So this morning; not being able to sleep, I snuck out to the dining room and slid the diningroom table and chairs out into the livingroom, pulled the wires off the back of the Brand "X" speakers residing there and plugged the M50s in their place.
