It's kind of hard to pick a single best because they're all really good in different ways. You'll be hard pressed to find a single pair of IEMs that suit all your needs exactly. The HJE900s can be good for classical if you EQ it the right way. If I HAD to pick one overall out of all those I would go with the Silver Bullets. They're a great deal and you can find them from a reputable seller on ebay for $70 shipped. Bugden is $67 but they are sold out.
Which out of those that you just recommended, would you say has the best OVERALL sound quality? i think its undisputed that the HJE900 is the best out of those for rock and hip hop but how is it for classical?
but it's good that you say they'll go back down " class="bbcode_smiley" height="1" src="http://files.head-fi.org/images/smilies//smily_headphones1.gif" title="" width="1" /> any idea when? and hopefully it goes even farther :P!
