^^^its weird, they were in tweeter store yesterday (they only have nice stuff) and they seem to have no online sellers, and their online site is not working.
When I first heard them, the salesman was touting them like they were the best thing since sliced bread. I wouldn't say they were awful, but they aren't remarkable either. I'd say they're pretty average. I think their's better out their for the same or even a little less, but their's worse for the same amount too.
I thought they were exclusively at Tweeter for a while, but I guess they've added a few stores in the last year or two. They were very few and far between. Someone here posted non-Tweeter dealers about a year ago.
If you really like them, then go with them. I'd A/B them against the Mirage line before making a decision though. The Mirage line may be a few dollars more, but it's more than worth the extra cost. I actually liked the comparable Polk speakers better, and I'm not a big Polk fan.

I'm pretty sure Tweeter can order anything from the Sumiko line (Sonus Faber, Vienna, REL, Pro-Ject, Primare, & SME). They don't have Pro-Ject TT's on display, but offered to order one for me.
