2 volt out is not a problem because it is a clean 2v. That is way better than a distorted (over rated) 4v output (think cheap 500 watt amp vs clean 100 watt amp). If you want more eq, and a really cool one at that check out the pxa-H100

I still think it is going to be a while for the iDA-X100m, I will let you guys know when it is ready to ship....
