I just did comparison yesterday. Between my HD650 (with toxic silver cable) vs a loaner LCD2r2. A friend of mine is kind enough to borrow me a demo unit of LCD2 before i decide my purchase. By doing the comparison...now i convinced and realized how good HD650 really is. I must admit the lcd2 wins in term of texture/clarity of the sound. But i dont think is by that much. And tbh..some songs i played...i still definitely prefer my hd650. Although technically lcd2 might better in some ways..but what i dislike about the ortho's sound is that I found my self very hard to get the vocal hooked into my head. I just dont know why. Looks like the sound that came out from my left and right ears somehow they did not focused being one right in the middle of my head which made me difficult to get the sense of life-like vocal. I listened many hours but still i found it the same. Swapping to my HD650...one thing innitially i noticed was the soundstage much better. Wider. And the vocal was easier to catch and enjoy. Thou the clarity is not as clean and crisp to lcd2...but is enough satisfying me. For comfort level....the weight of lcd2 while on my head..is a bit too much. During 1st 20 minutes was fine...but after that i felt like the clamping was too tight as well. So for the comfort level....hd650 is WAY better than LCD2, at least for me. So now i am gonna return this LCD2 and maybe i will get the hd800 instead.
He told me to try the lcd3 as well...the sound shoud be improved from lcd2....well...for that price..it better does ! ...but no thanks
