I'm looking at starting my first HT system with the new Infinity Beta Line. I'm looking at using the Beta 40 towers up front, Beta C360 center, and 4 Beta 20 bookshelves to round out the 7.1 system. Probably gonna user HK to power the whole thing. Any comments/opinions of the new Betas? I've heard them, and they sound just right to my ears, but I would love to have a few other speakers to audition before I buy.
