Well, my LCD-2 is rated at 90db per mw at 60 ohms and the newer ones are 94db at 70ohms, so if thats not more efficient...
I know, I mean that despite the unflatter response, it has the same level of sub-bass as mine, but a bit boosted bass, so the contrast might sound as you say, less bassier due to the less sub-bass, but still, mid hump may be stronger like in the HD650 more or less.
But as I said, i dont really feel that A/B would make a deal difference, at all. So to all Fazor owners, dont worry about sub-bass, it is there, will be and you'll love it.
God, sub bass is even awesome with my matrix m-stage.
I hadn't realized that the sensitivity had increased as well, thanks for clearing that up.
I'm glad that the sub-bass is still there, I was getting worried, my LCD-2 are on the way and I'm going to be listening to sludge/doom metal primarily on them. What you described sounds perfect.
Thanks a lot for the comments. I'm feeling a lot better about my purchase.
