Ok, thanks Dkarmeli. As just about everyone knows, I currently use the S4700s. It's not a bad speaker at all! Pretty damn good even. But they need a lot of break in time. They weren't very good right out of the box. Also, they're very sensitive to equipment changes and quality of said equipment. If you use a cheap receiver or amp/preamp with these, you're gonna be disappointed. So, they're very revealing. The upshot is that they're easy to drive. You can use a lower powered Class A amp with no problems. Also, they are not too sensitive to placement and they sound great off-axis. So yeah, it's a good solid choice in a high end speaker, imo. Sure, you could do better (at a higher price though,) but you can definitely do worse. At the current list price ($15k) they are a bit overpriced, but from what I understand, there's some great deals on this model as well as the rest of the Synthesis line out there.
