Honestly Kunlun, I am not sure that I heart the relevance of your question. I speifically don't think that your question can distinguish between quantity and quality of bass because you don't seem to be making a distinction. You seem to be taking a fast food menu attitude to IEMs. (Can I have an extra spring roll with that? And a little more bass.) Headphones are organic - they are complete systems. So if letloverule says that the ES5 are not bass shy, his point is that the ES5s have the right amount of high quality bass.
Anyway, comparisons will come. Just don't miss the forest searching for one big ol' fat-ass tree. :-)
(BTW I like you website. 明 is indeed a fine character.)
