With the lcd2 the vocals were clear with percise edges to there location. With the lcd3, the vocal was fuzzy. I prefer to call it smog like on a sunny day you can see the persice skyline of LA but on a different sunny when you look it is still easilly seen but the skyline is a little fuzzy due to smog. Some of the albums I noticed it on were high resolution music. If anything, the lcd3 seem to be the ones covering flaws up because it was a lot easier listening to badly recorded music with them than with my lcd2.
