room makes or breaks

just a statement. i've been into this hobby for about eight years now, i adjusted and changed gear a good bit over the years. my last room was more long and about 14 foot wide, i recently moved and set up in a room about 20 foot wide and not as deep.
i am just amazed at how much better my system now sounds, speakers have vanished ,every aspect has improved, dont know if i lucked into a sweet spot, but the room has made a HUGE diff. im pleasantly blown away, like i bought a new system.
