I auditioned the 604s and 703s with Rotel equipment at the dealer. I liked the 703s better than than 604s. I would have thought that the 604s would have matched up with the M60ti instead of the 703s, but no. The 703s are quite nice to look at however. My son has 703s with a Denon 3805. He thought he could do without a sub until he heard my EP500. I believe he is looking at an SVS 20-39 PC+.

I think the 60s are great speakers. For the difference in the price I had to upgrade to the top of line model.
