I would like to know what amp you were using while getting those results!I agree if you EQ the bass a lot it can be very rumbly, but it really loses tightness and the controlled punch. If rumble is what you want, EQ can get you that, if you want a base that can stay tight, punchy and can still rumble when boosted with EQ, look to HE6/SE.
I just want to put things in perspective, I have an LCD-5, and it is indeed cleaner and quicker in bass, but when EQing to the max, HEKSE delivers while LCD-5 has a "cap" until bass doesn't increase and it just makes everything bloated. I have also tried Susvara on a ~20k chain, and I have found HEKSE had more bass punch than Susvara (don't get me wrong, Susvara was better in EVERYTHING else by far at that level, including better bass texture on Susvara, even if HEKSE can punch harder without bloating)
