Anyone demo or using new B&W 683 S2

I had a very good demo with them over the weekend. I'm seriously considering bringing home a pair to demo. I heard them with a Marantz pre/pro amp combo in direct mode stereo. The only thing that concerned me was maybe a tad too much "sparkle" in the lower treble upper mids. But that only showed up occasionally. I spent a couple hours with them. If anyone reading this has demoed or has the 683 S2 I'd appreciate any thoughts. TIA.
