Holy wow. Thanks for all the responses, you guys. I'm extremely appreciative. I was thinking about buying the E7 just as a dac/possible amp if the Superlux if it was necessary but since you've said that, I'll skip it.
As far as the E1, I already have it and just use it as an iPod line out dock.
Now, as far as headphones go. If I was to stay in this price bracket, it seems I'd want to get the HD 668B's. However, you've suggested Grados to me.
I already own a pair of RE0's (IEMs) which I'm not sure if you're familiar with, but I love them to death. I've heard that some people don't like the "harshness" of their highs which I enjoy. I've also heard that Grados are super forward and "in your face". Sometimes a little too much so. Will that be a problem?
I took a look at the M-Audio Q40's and although they seem nice, they're a bit expensive although I could consider that price range. However, people have been describing it as a "Bass heavy" headphone. I'm by no means a basshead, but I do enjoy my fair share for Electronic music (Think house). Will this be over the top or is it just about perfect?
By the way, these phones are going to be mostly for home use, I just tossed the library question in there as an afterthought. My roommates may be disturbed, but I just want to make sure that I won't be absolutely killing them.
An aside: If a headphone is "Amp recommended", does that mean I should or shouldn't get an amp? Will it not improve nearly as much as I think it will in SQ?
