... I'd like to straighten out some things.
If you could live with an open design, you won't find a better headphone under $200 than the HD 580 – even without an amp. I's been said that it imperatively needs an amp. That's not quite true. Technically speaking, there's absolutely no need for a separate amp, additional to the one that's already built in in your soundcard, your portable device or your receiver... (well: what exactly is it?). The HD 580's 300 ohm are even an uncritical value for average built-in headphone amps, except for one criterion: efficiency or power reserve respectively. It depends very much on the actual device – you may be lucky that there's enough juice, or you don't listen too loud anyway...
I would say there's a very good chance that you'll have no problems at all in this regard – the HD 580's sensitivity is quite good, apart from the high impedance. So it suits my SB Live Platinum HP jack well, and the music is quite enjoyable this way. You really hear the HD 580's superiority over mediocre headphones even with such a «crappy» source. But one thing is true: it's one of the phones that gain very much if you have a good amp to drive it with. And it's not the «juice» that makes the good sound, but solely the amp's sonic character, the synergy it makes between it and the headphone, maybe additionally its output impedance, though this one is slightly overrated: e.g., my HD 600/EMP combo – the latter with about 120 ohm output impedance – is an ideal match.
But the HD 580 is also very revealing (though some say it's veiled itself...
). It will show all the shortcomings of your source, too. So be warned: there could emerge the want to upgrade the latter...
