Just make sure you demo what you are considering. Never buy blind! It never works out! I mean unless you have the cash then go for it, but if you don't like them you'll have to sell them, and if you don't have the cash flow, you'll be stuck with them for a while until you upgrade.
I was a big Klipsch fan. I agree high sensitivity speakers do dynamics far better than any other speakers, period. But their drivers aren't all that sturdy and great, just look on YouTube at all the people who buy them and end up adding internal bracing in the cabinets, and dampening the cheap thin metal drivers.
Dynaudio speakers are nice, but they require so, so much power to make them sing, that's just not my cup of tea. And Totem, Eh, maybe for a bedroom, but they suck at hard rock, and rock and home theater forget it.
This is so subjective. For me, I think Sonus Faber are pretty sweet.
I heard a lot of good things about Salk, but it's online purchase only, albeit I think you get a 45 or 60 day in home trial, I think. If you don't, I wouldn't bother with them.
