True, my last few main headphones have leaned to the side of clean, tight, punchy bass over big bass.
The reason I got excited about the Ed9 when I first heard it is that it has big bass, but it is still tight and punchy, even with fast material. Sloppy bass is the enemy My first though upon hearing the Ed9 was "shoot, this is almost like an L3000." True, the L3000 does have slightly more impressive bass, but it's also a lot more expensive and discontinued.
To date, I've not heard any headphone, other than those two, which could provide a very powerful bass without sounding overly bloated, flabby, sloppy, slow, etc. The Qualia in the right system has the best bass quality of any headphone I've heard, but simply due to frequency balance, it just doesn't quite reach the punch level of the aforementioned pair.
So I'm looking at the Ed9 to provide the "sick bass" as an alternative to the more open, airy W5000. I bought the W11 thinking they might have had a chance to do it, but I the Ed9 will give me a higher degree of contrast.
