I have a chance to get a pair of PolkAudio LSiM707 tower speakers at a great price. I have had a few minutes to set & listen to them but it was too short of a session to come to a conclusion on them. My question is what are your thoughts on PolkAudio speakers? Anyone have experience with this new LSiM line?...thoughts? I have never owned PolkAudio & am going to start reading reviews & things on them. But i am a regular here & have gotten a lot of great help from you all, so naturally id love some feedback from you all. You can see from my signature that i currently own B&W 600series. Would these Polks be a nice step up? They looked great from the little time i had with them. Big but i liked that about them. I could also get the 705s at a great price so maybe they would be better suited for my room. But id just like some thoughts/experiences with either of these 2 speakers, 705 or 707. Thanks guys!!!
