I have a formal looking living room area that I don't want to put floor standing speakers in because it would just look bad so I'm looking for a good pair of bookshelf speakers that have amazing clarity, sound stage. I'm limited to the speakers being about 5 1/2 feet apart with a listening distance of about 15 ft. I keep hearing about Focal Aria 906 or Elac Debut Reference. Right now I am currently running an REL T-Zero with Klipsch RP-500s and I'm thinking I could probably do a little better.
