I am not ready to cross of the ES5's just yet. I'm not entirely sure whether or not I can be considered a bass-head per say, but I as long as the bass is good, clean, deep and doesn't interfere, there aren't really any reason for not liking it, in my head. To put things in to perspective, I can still enjoy my Grado SR60i which aren't bass heavy at all, but I can also enjoy my Westone 3 which doesn't lack bass to say the least. I do like the thought of the ES5's midrange, as it is described as some of the best.
The fact that you have such a wide preference in music really interests me, as I do tend to listen to quite a lot of different music, and I'd hate spending that much money on a pair of customs and think, "Well, it does good with this genre, but with another one, it's sort of meh,".
In the ES5 thread someone painted the picture of ES5 owners sitting on their front porch with a glass of wine, looking in to the horizon. The JH owners were portrayed as long haired dudes that rocked out. Taking my primary music genre into consideration, I'm the latter, but when you look at my music preferences as a whole, I think I'm sort of a hybrid between the two.
davidcotton: I'm not exactly looking for more bass from my W3's, as they do have plenty in my opinion, but other than that, it is definitely a viable option that will be considered.
