Thanks. With the LCD-3, while the bass is very well delivered, it seems to me that it is less aggressive now. This is the thing that prompted my earlier post on the 500. I have to do another intensive round of listening (poor me ) but I found the everything about the bass in the 500 to be a tad more aggressive than the LCD-3. I am sure a lot of Head-fiers are scratching their heads on reading this (me included). The LCD-3s, IMHO, became a tad brighter overall but definitely not laid back.
Cool. About the HE-500's bass kicking harder than LCD-3, makes perfect sense to me. On all the speaker taps I tried, when HE-500 is driven properly, it almost gets the control of the Audeze's, but kicks harder, the natural bloom you might say.
