Okay, bit by bit I've finally made my way through this whole thread to date. I'd be curious to hear more impressions with hard rock, metal, alternative, etc. I'm guessing the sub-bass makes for a great kick drum, and the detailed highs are probably good for cymbal strikes etc. What about vocals and guitars? Are they aggressive and energetic enough for electric guitars and snare strikes and so on? What about bass guitar lines typical to these genres--do they get lost in the mid-bass/lower-midrange dip, or are they buried behind drum kicks or other instruments? Other impressions or thoughts? Other cans under say $350-400 that would be a better choice for these genres where PRaT is king?
My main frame of reference is a pair of HD-25's which are quite enjoyable for these rock genres but can be a bit fatiguing at times.
Miow, do you have access to an iPhone/iPod and LOD you could try with your C421/2227 and the K167's to see how well they do without Sony's ClearBass?
