In my last post, I had just received my SVS Ultra Evolution Nano speakers. They lasted almost three days with me and I sent them back. I went to my theater room and grabbed a pair of my B&W 706S3 speakers that I was using as my rears to test them out, and I found what I was missing. I am going to order another set for my basement and leave these in my office. Very happy with the improvement in sound quality.
