As a long time Sennheiser user I was torn between these LCD-2's and the HD800S. I chosse these! It wasn't a factor of cost - these have a very natural sound - they just sound "Right", A wonderfully balanced full bass with realistic Midrange and top end. The HD800s is not quite so full in the bass but is more detailed in the high end which some might find more to their liking. This slightly less pronounced treble makes it remarkably tolerant of different source material. If you can stretch this far they are heartily recommended!
