If everything was simply about getting things loud enough. I think we can all just get the Fiio E11 or even the E5 and call it a day. I believe almost all headphones will get "loud" with lots of tiny little amps or even an ipod. It takes some experience to realize it just doesn't sound right or that volume doesn't equal drive necessarily. I know analogies are pretty useless, but I always tell people I can hit 60mph using a 35 horse power engine in my car, but I would rather have 450 horses under the hood, it just feels different even at the same speed.
Edit: I would hold off on the opinions about power needs until your Emotiva comes in. I bet you'll be singing a different tune once you hook up that bad boy.
Agreed. Using your analogy, 60 mph on a 35 horsepower will barely have any control and can only deliver at certain peaks/times. Having the extra juice in reserve, you definitely notice so much more control. Even at low volumes with Emotiva you can get decent bass.
@jsaliga Although I'd even give the Emotiva some time to burn and also for you to get used to the Emotiva sound.
