More BASS : M50's OR AH-D1100? - Page 4

1) I actually have Denon D1100 coming my way but I ordered from UK to Finland so it'll arrive at like 15~21th Dec and I ordered to my parents place where I will spend the Xmas holiday. I believe D1100 are the only headphones at this point that might be more to my liking than the XB500 as I've spent perfectioning the XB500 by EQing still a half year afterwards and I still keep lowering or boosting some values by 0.1 increments to find the optimal (yes I'm a perfectionist). HFI-580 I think could be slightly too bright for my liking and the bass slightly too weak. I'll write some impressions later when I test them but since the equipment at parents place isn't the optimal and I will only give some impressions at that point but I plan writing an in-depth review later after 2th January or so when I return here to my appartment.

2) Yes it's possible to have both punchy mid/upper bass and strong deep bass. That's what XB500 have but it's very rare for headphones to deliver both a strong upper bass and deep bass at same time. AKG K 518 DJs for example packs a VERY strong upper bass but lacks in deep bass. Also XB700 for example ONLY delivers the deep bass. If XB700's deep/upper bass focus is like at least 70/30% deep/upper then  XB500 is like 45/55% but that doesn't mean I concider the deep bass on XB700 to be that much stronger, in fact I feel XB500's deep bass is like at least 90% of that of XB700 but at same time it feels like the upper bass is like at least twice as strong which XB700 lacked in and this results in a very good balance vs deep and upper bass on XB500. D1100 seems to also deliver both strong deep & punchy upper bass and feels like it's got capabilities to perhaps even deliver the optimal 50/50 balance ratio between deep & upper bass that's what I'm kind of expecting, just a tiny bit less punch & impact compared to XB500.

If I listen to a lot of pop music, do you think the 580's be a better choice for me over the D1100's?
