That is true, EQ is definitely a viable option as the HD 598's I've found are very respondent to amping, especially when compared to other headphones. However, to a certain extent that has a limit- that is a clear sign that I've probably chosen the wrong phone, but honestly that's the only thing I have a problem with the HD 598's.
I've listened to all the phones in this price range at some point, I didn't especially like the Beyers, the AKG just too analytic and difficult to amp, etc, etc... I have tried the HD 558's personally and though they sound good, the bass from my ears can bleed a bit and after hearing the 598's, I couldn't justify getting them for the lack of soundstage and smooth mids compared to the 598's. (559's? I assume you mean 595's, in which case I'll try to listen to later.)
Should I instead get the X1? I've heard they are very good and better than all the current HD's under the 600's. Perhaps I should get a more expensive headphone? But then again, I can't afford it at the moment. I'll probably keep the 598's though until I have the money for a more expensive 598-like phone with a bit of bass improvement and an amp for it.
Yes, I meant 598 not 559. Sorry for the typo.
