Would you guys say the HD558 are closer in sound quality to the HD598 than the hd518? I tested the HD518 and HD598 over the weekend, and didn't really like the 518 at all. loved the 598.
The cost of the 558 is much more doable for me as a future upgrade for me than the 598.
Also, this thread has been a great help to me guys. so thanks!
The HD558 and the HD598 use the same drivers and responds well to an amplifier.
The HD518 is designed more for "unamped" sources.
So yea, get the HD558.
