I have been a klipsch guy for several years now, but I think I am beginning to want more warmth and depth in my music. I am looking for a decent 2 channel or possible 2.1 system for my office/ bedroom. I love the look of the AV123 Elt 525, but I am worried about its inefficiency. The Polk rTi a1 are my other option at this point. I have never owned polk audio, what are their sound characteristics? I am replacing some old Bose 141 speakers that have performed, in my opinion, valiantly for almost 10 years. The Bose still produce deep sound, but it is muddled. Could someone please help me out with the strengths/ weaknesses of these two speakers or any others that may be a good bet for approx. $300?
