I grabbed the CR8's and the sound is stunning. It's taken me a few hours to understand them because the CR7's have more pronounced low end and the highs have more sizzle, but the CR8's are perfectly balanced. The lows have much more clarity and don't get muddy even when I tried putting them 2" away from a wall. The highs are much more detailed. I would like a bit more 14k or so to give the sound a bit more sheen but cymbals sound much more like cymbals over the CR7's.
But where these things shine is the high mids. They either just weren't there with the 7's and when I booted them they sounded a bit harsh. I listen to all kinds of music — from classic country to jazz to proper Chicago house and Detroit techno, from Talk Talk to My Bloody Valentine to Mike Nesmith, Nat King Cole and Eddie Blazonczyk — and these speakers made everything sound beautiful. Female vocals are gorgeous, from early Curve to Cocteau Twins.
I'm ecstatic that I found them in such great condition. One of the grills is dented but I don't use them anyway. The drivers and baffles are spotless. I cleaned them up like I was on a mission from God and they look great.
The kicker: I bought them from an very nice Elvis impersonator from Indiana. As I mentioned before he was asking $40 for them, local pickup, but they were in such good shape I ultimately offered him $100 and now I have them. He packed them so well, covered with rubberized shelf liners and newspaper, in two separate boxes.
Can you tell I'm happy? This made my year.
