To each their own. Technically work on the LCD-2 never stopped and measurement wise they've always been better than LCD-3, especially on noise floor and resonance. But in the end the LCD-3 needed such aggressive gear to wake up that it had to go.
Confirmed once the LCD-2 landed. My best pairing with the LCD-3 was too much and I sold it right away. Now I can go back to neutral amps and get the same natural result that took aggressive amps to achieve.
That said if you prefer a more passive sound... the LCD-3 is certainly more up your alley. Or put more bluntly... if you can keep the HD800 for more than a week, the LCD-3 might also work
It's also the same reason I dropped the Stax SR-007 MkI for the LCD-2 Rev1. Though perhaps technically better it also had a more passive presentation. Likely a big reason for not jumping on the SR-009 other than the monster price
