Anyone going to comment on the bass boost remark?
I think what's happened is a couple of people who don't own the amp complained about the lack of boost so it has been changed.
From what I have read, everyone who has this amp likes the current bass boost and does not want it changed. I've tried to buy v1 because it looks like the superior option, to no avail.
Maybe James fiio should have a vote as at the moment this change seems to be turning people of this amp.
Well, I maintain my previous position: the current bass boost is good enough. It should not change. It's addressing the low-bass roll-off of certain headphones and systems quite elegantly while keeping frequency response elsewhere even and balanced.
I hope that if Fiio is changing the bass boost, then they at least offer the old version alongside the new version. Maybe call the new version E13, or E12B, or something.
