I noticed Polk is selling some refurb 707's through their ebay store for a little over $3000. Currently I own the PSB Synchrony One's (main room) and the LSIM 703 (bedroom), and am pretty happy with both. I have not heard the 707s but would imagine they are very similar to the 703s as the drivers are identical except with the two additional 5x9 woofers. For those who have experienced both does anyone prefer the 707 over the One's? Or is it more of a lateral move.
