Totally agree, I love 'em. They are my "fun" phones, and my choice for strings. I actually just installed some Lawton pads on them last night - I like the big pillowy look and they seem more comfortable - and immediately fired up Christian McBride's Too Close for Comfort. I defy anyone to listen to that through the Denon's and NOT be tapping toes and bobbing head by the end of it. Awesome!
I might be doing the elastic band headband mod on my W3Ks - they sometimes slide down a bit during extended listening. They definitely seem designed for Ernie rather than Bert.
