I am considering replacing my Polk Audio RTi38 front mains with a pair of floor standing speakers. I prefer neutral sounding speakers and I have narrowed my search down to the Energy C9, KEF Q7, Polk Audio RTi8, Paradign Sudio 60, and the LSI9 or LSI15. I have only listened to the LSI once or twice and was not paying attention anyway at the time. According to Polk, the LSI has better "resolution". I have listened to the Energy, KEF and the Paradign quite a bit but it is impossible to AB them. I am hoping to hear from owners of any of these speakers.
