I'm looking to add another system to the house and currently have the RT polk's. The room will be approx 20x14 and I want to stay with the bookshelf size speakers. I have not yet heard the LSi9's yet but will soon, but I love my first set of polk's so I am somewhat biased. What I am thinking is that the 805's are probably superior to the polk's but do they justify the price? I will be using them in about a 50/50 mix of music/HT so they need to be versatile. I know my own ears are the judge but I would like to hear from people who have listened to the 805's and the polk LSi's.
