That's one of my main fears for the Shures, I can actually purchase both the KRK KNS 6400s and the SRH440s somewhat locally,

So I currently use a pair of Koss Portapros, but I'm looking for an upgrade for about $100 USD. After a bit of browsing, I've been able to narrow my search to these three: KRK KNS 6400 Shure SRH440 and Denon HP700 I listen to practically every genre of music and also game...
