I bought a pair of Xones a couple of months ago, tempted by the low price and having heard them driven by an all Leema system (Tucana amp) at a show. They are fighting it out against my resident B&W 805S. They have been a very enjoyable listen due to the nice tweater, the speed and the transparency. The imaging and the detail and agility are quite addictive. Bass light, not really, they deliver good bass but they are maybe not full bodied. They also scale down the big dynamics, but in a nice way. I believe the Xones are a bargain if you appreciate them for what they can offer.
I have not heard the Elas but from a quick bit of research looks like they might share similar strengths. (I'd be interested to know how they compare if you find out, if the Elas come close I will definitely be on the look out for a pair for a friend).
