I think punchy is the wrong word. It's not that the Xcape IE lacks punch. It's more a matter of sensitivity. It does respond well to EQing and does fill out well doing so. The Xcape IE is more geared around the midrange with lighter emphasis on the extremes. Techno tends to hover more around the extremes, so product geared for that fit better (like the Triple.Fi 10).
We were talking about impact on bass, I think you can find headphones that are better in this area and I'm not sure Xcape IE will provide enough punch in lows for electronic music. If I compare with V1, bass improved, not because it's a bit more present, because it is more detailed and controlled, with V1 lows were sometime muddy or not responsive enough, that's what I feel.
