Here's James post regarding the two bass-boosts,

the blue lines represent the v1 boost while the rusty red line is the "revised" boost. It really only "peaks" at around a 5 dB boost, though James earlier said before the graphs that it was like 4 dB of boost, which I assume is like looking at as "how much boost is there on average."
Technically a lot of headphones (especially Open Backed headphones) typically have a sub-bass roll off. Here's frequency charts of a few popular headphones on head-fi, to get an idea how the frequencies will "stack up" with the Mont Blanc's bass boost:
Now for some "I think"s:
The Q701 I have has pretty good bass extension (though not very high dB), and rolls off just about where the Mont Blanc's (optional) boost starts kicking in. So effectively, the new combo just has deeper "bass extension" above 0 dB rather than enough to change roll-off into a "Woah!" upsweep.
Looking at the graph again, the new curve has the same "peak" boost, though slightly forward. Technically that will affect more notes and will net a stronger bass in the combo with a headphone that already has decent bass extension. However, I haven't heard the new model. And based on how much change I hear from songs featuring deep bass when I switch between on/off boost, I think it still will be a largely subtle difference (though more frequently heard). Will it still be as refined and sound as controlled? Dunno that. I know there is more to quality that isn't defined just by quantity (and of course enjoyment is flavored by personal taste). I still think the current boost is more versatile and fits really well with the Q701s
Here's the E11's Level 1 & 2 bass boost (on high gain, note that the graph starts at 10 Hz instead of 20 Hz like above) for reference, especially for those who have an E11 to hear now:
Surprising number of people using the Q701s here! Cool! Hey buddies!
Also, you and I may not be bassheads, and aggressive boosting may be a niche taste, but lets do what we can to respect other's tastes while asserting our own... "Catch more flies with honey," y'know?Edited by Evshrug - 2/15/13 at 5:24am
