Yeah NT6 is bright, and SE5 is similar to LCD 2. And I just got my LCD 3 yesterday, the brightness is between SE5 and NT6. Great imaging. Once again I am amazed how SE 5 way can even technically keep up with LCD 3. LCD 3 is only a bit more neutral sounding (especially mids) than SE5 with smoother, more liquid-like presentation and more space/air. SE5 is closest to the absolute audiophile sounding CIEM when driving in the right system.
Good to know, thanks!
