I received my E07K yesterday. I think with many so called "Re-Mastered" CD's and recent recordings the master volume is overdone and when a singer's vocals peaks I heard this "crackling" noise. I guess the little e6 just couldn't handle it. Never had this problem with low bit rate files (128-256 kbps). Played those same songs again with the E07K and its gone. It seems my DT1350 was a bit under driven with the E6.
I think the sound signature has softened up a bit though (never used any bass boost on the e6). My DT1350 is still energetic and aggresive enough but it seems to be less fatiguing to listen to after an hour of straight listening. I think I prefer it.
Listening to Pink Martini right now on the DT1350. Wow!!!. And yes, the soundstage is improved too. More spatious. For sure. For closed I'm very pleased. Bass sounds more punchy and tighter. Loving it too!!!
I prefer taking some of the warmth AWAY and pair it with the iQube. I think that makes the DT-1350 shine and the synergy between the two is great to my taste :-)
Mine shipped today. Another Christmas present, just won't be received till next week.
I bought these because of what I've read here and I've heard (pun intended) they will match perfectly with the Fostex HP-P1. Using the 1/8 impedance rule its like the DT1350 was made for it. Anxiously awaiting it's arrival!
Merry Christmas everyone!
