I have already listened to the LCD2 Rev.1 for a while, but I had no direct comparison to my other cans.
It's very hard for me to make a decision here... maybe I'll be able to compare my cans to the LCD2 at home, some day...
Is generally someone here that finds the LCD-2 inferior to the above mentioned cans (DT880 (2003), DT880/600, D2000, HD650, T50p, HFI-580, HD600, K701) when it comes to pop/rock/country/blues music?
I think this is something you're gonna have to decide for you're self if its worth it, taka a listen to the lcd 2 first then decide. selling all the cans you mentioned without listening to the lc2 first is probably a bad idea. my suggestion is take a listen to it first then you're the one will know the answer better.
