Jolida 1501 sound gone from great to eh. Help

hello,
I got my 1501rc to replace an arcam a65plus. I run it with sovtek tubes and JmLabs Chorus 706. The tubes really help to smooth out the metal tweeters. In my small bedroom the sound rocked. I listen to all kinds of music and this amp had good bass, decent soundstage, great midrange and highs. The speakers were about 4 feet apart and about 2 feet from the rear wall. I sat about 5 feet away. I had a rug in front and a nice tapestry behind me.

Ive moved into a new apartment and put my stereo in a 12x20ft living room along the 20ft wall about 5 feet apart 2feet from the back wall and I sit about 6ft from the speakers. The sound is now unfocused, bright and has poor imaging. I only have a couch in the living room and nothing else (cant afford furniture right now). Is the sound the result of the bare furnishings or should I look to switch my system around somehow.
