The LCD-2s were manufactured in May 2012 and are rev2. I picked them up used and were in excellent condition. I liked them immediately, but once you taste the LCD-2s your mind starts to question as to what does the LCD-3s have to offer. I was able to get a used LCD-3 (manufactured in August 2012) in excellent condition and I'm extremely happy with them. The bass is phenomenal (very articulate and defined) and the sound stage is wider than the LCD-2s. The mid and upper regions also sound more forward to me. Are the the LCD-2s twice as good as the LCD-3s at twice the price? No. If I hadn't gotten the LCD-3 at the used price, I wouldn't have bought them. The LCD-3s do not represent a substantial value for your money over the LCD-2s. The LCD-2's greatness is not multiplied by 2 in the LCD-3s. The LCD-3s are a step up and not a giant leap from the LCD-2s.
I'm no electronics guru, but I think you or any of the other experts on this board who know how the inner workings of the 105 operate can best answer the question of "Can the headphone amp be easily modified through a firmware upgrade?" What do you think?
Not! Nyet! Nada! ...not me at all!
On a serious note and please understand that i don't mean to be indelicate, but when you buy used headphones, aren't you concerned about what i consider the "eek" factor, i.e.they've been coated with someone else's earwax? Apologize for the unsavory subject matter as really no offense is intended.
