No, I'm not personally looking. I just find it really controversial around here.
Bass charateristics might include.....
-whether it distorts
-amount of extension
-slam or weight to the impact
That's just to name a few. I use to think W3 bass was superior to W4 just because of qty and fullness is more on W3 but there is a lot more that goes into it. I now realize W4 is technically superior. But I DO think that if you can add in an underlying "fullness" (not necessarily a boom boom subwoofer affect but a fullness) without bleed it will be more desireable. Afterall, whether speakers or headphones or IEM's I think we all desire a realistic live type presentation.
But, yes, after all is said and done it is still very much a personal preference.
