Whether they "sound better" is going to be subjective. My HT is all Polk Audio as well, and we polkies tend to like that sound. I am more of a vintage polkie (a nice way to say old) and may be a while before a part with my RTA-12Cs of 20 years. However, I have been intrigued by the Rockets by Onyx line of speakers. It sounds like the Outlaws are targeting a similar line and I think that's very smart. The brick-and-mortar showroom speakers are getting outrageously expensive (B&W, et. al.) and, sad to say, my polkies will not live forever.
