Easy choice - Sound Lab U1s. Assuming you have the right electronics (great tube gear such as the right ARC or Atmasphere or VTL, etc amp and preamp) and you have the right room this is a no brainer. You will get outstanding deep, tight, bass, enormously realistic midrange - vocals will be in the room unlike anything you've heard before, and beautiful, delicate highs. You will get high definiton, transients, texture, detail, air, transparency, and precise imaging side to side and front to back. You will get the most amazing, realistically musical experience possible. Just make sure the room dimensions and treatments are as good as the speakers and electronics - at this level, the room is a huge factor in letting the gear do it's magic. (And of course you need a good source - analog and/or CD.) Ok, this system might stretch your budget a bit, but no sense in going 80% of the way. (If need be, you could scale down a SL model or two.) Let us know what you decide and how it goes.
