These are great little speakers. I auditioned lots before I decided on these. They have a really solid low end and all the detail you could hope for. Even with a relatively cheap amp they sing. And the build quality ... brilliant. They look great with their grills off. The only thing I would improve would be to have real wood ... but then they would be much more expensive. Another thing is that they are quite heavy so be sure that you have good stands if you plan to put them in the wall (they almost pulled out of mine!)
I don't know why I don't see infinity products around in the UK more ... perhaps they are a US brand? I can't praise these little babies enough and would definitely have infinity at the top of my list in future. I recommend you audition them or, if you find a cheap set on ebay, snap them up straight away ... they are sure to be a bargain!
