Hi Armando,
I don't regret buying the CS4 at all. I was just wondering if it would make more sense for me to have a smaller center. My room is not that big (14x20) and if I can save $$$ with the smaller aerial....
The CC3b does have a reputation as one of the best.
There's been much written about the importance of the center matching the mains for HT, but since it's on a different plane, even when tilted, it's never going to sound the same, in my experience.
Anyway, I'm probably going to keep the CS4. It's unbelievably clean and neutral. The looks don't hurt either.
Are you still looking to buy the Euphonias?
Jose.
