Thanks!
If price were not a consideration, I'd want either of the top 2 on my list. There's something very compelling about the HD600 though because while its pricy by the normal standards, if it ever should fail or get nicked, dented, dinged... its not nearly as heart breaking. Even the Koss Porta Pros are quite a value all their own.
I also feel that a good in-ear is a totally separate commodity. Because I feel it performs amazingly out of an ipod and gives off the best isolation, I'd probably go for the ES5. But if I were to bring an amp into the equation, I'd probably go for the JH Audios. The JH13 in particular is mindblowing. I think the UE10 is a slightly different sound that has just slightly more forward mids than the JH13, but less sparkle. I would like to find out if the JH10 is exactly the same design as the UE10 used to be.
Anyway.... I think a great selection of headphones would be something comparatively neutral like an HD600 or an HE6 or an HD800
Then something closed back and a little thicker sounding maybe... like a TH900 or D7000
and then a good in-ear. If you're going the universal route, I would consider any of the top 3 Westones as they each excel in different areas, but I do think the Westone 4 is the best overall.
I hope this sorta answers your question. haha. But I would want to have the Orpheus over all other headphones probably or the SR009 or the R10s..... the top 4 on my list
