my sennheisers came back in from warranty today. it’s so much better now. it’s sort of weird because i’m readjusting to the neutral sound – i’ve been using my grado sr60s on my computer in lieu of my sennheisers, the grados were much better matched to my pc output- it’s brightness and the low impedence really gave it an extra punch. all the same, i’m glad i have my sennheisers and that their back in working condition. an x-cans hp amp would be awesome, but um.. that would require spending money.
