looking at them they appear to be a nice looking version of a DIY single driver speaker. They're probably pretty good for the price, but I find it hard to believe they're a giant killer. If they were then there would be more reviews
I'd really like to have a set of B&W 805 (I mention these since the TAD seems to be copying them) to set beside my friends TAD speakers to see just how much more you get with the extra $2,200. I've heard the 805 hooked up to unobtanium gear (for most of us) and really don't think they sounded much, if any, better, but side by side may shed some serious light - and I really hope it would.
If you are on a budget you simply can't go wrong. I would love to hear other speakers that sound as good in the same price range.
