Sorry if I came across that way, but I'm not offended, just kind of baffled that you would think it's a basshead can. It makes sense now since you haven't tried a pre-fazor one and made a guess based on others' opinions/impressions. Maybe some people over-exaggerate the bass quantity here I guess.
Anyway, I believe the reason why people liked the bass so much (I loved it) is because it digs really deep, and has decent/good punch. But most of all, the texture and quality of the planar magnetic bass the LCD-2 was just stunning.
When Audeze introduced Fazor, the sub-bass was significantly rolled-off and the impact also felt reduced (might be placebo), but the major change was the roll-off. It doesn't dig deep into the sub-bass regions anymore because of the roll-off. The 'magic' of the LCD-2 bass which blended so well with it's dark and lush sound was lost, which is the main reason for the out-cry I'm guessing. People would exaggerate by saying things like 'no more bass' I reckon.
Anyway, cans like the V-Moda M100 or JVC-SZ2000(a real basshead can) absolutely beat the LCD-2 pre fazor in terms of bass
quantity, but not quality obviously. And the LCD-2 had major QC issues, even pre-fazor, where the sound of each LCD-2 would differ from user to user and high driver failure rate. I believe the Fazor implementation reduced that inconsistency problem and also driver failure rate, but don't quote me on that.
EDIT: To give you a general idea of the difference -
pre-fazor vs
fazor
You should be able to see that the LCD-2 even pre-fazor is relatively neutral (except for the upper-mid to lower treble dip), and the significant roll-off in the sub-bass of the fazor that generally starts at ~30Hz. I certainly wouldn't classify even the pre-fazor as a basshead can.
