Ok, I have done quite a bit of research towards getting what I want out of one or two pairs of cans but I would still like some input from the folks here. I mainly listen to big band jazz and techno, I also want a pair of phones that I can use in places other than my home. I'm looking for something that can really bring out all of the tones in the jazz as it has a wide range of frequencies. Most importantly I want something that would bring out the highs a bit above the rest, for this I'm thinking sennheiser hd 650's. As for the techno with the low electronic bass and all that I figure that the hd 650's are not going to cut it. So I thought that the shure srh840's would be a good choice considering I don't have loads of money to spend. However, I have heard good things about the bass as well as the mids and treble in the denon d2000's. I have also heard that they do not isolate very well and as such I might not be able to use them in public places. Would it be worth it in the long run though to just go for the d2k's instead of the srh840's? Also, I would also like suggestions on what amp/dac to buy as I do not yet have one. I for the time being I plan to source these from my htc evo, ipod touch 2g and my old compaq laptop. Eventually I would like to upgrade my source, and ideas there?
So, that's about it. Sorry for the one long paragraph. All suggestions are greatly appreciated.
