Hello ALL:
Regarding the relatively inconsistent and/or contradictory statements regarding the perceived sonic qualities of the Ether C's...
I received my Ether C's a couple of weeks ago...and initially, (feeding them with a Schiit Audio Yggdrasil D/A signal converted signal, the phones driven by a Schiit Audio Ragnarok, balanced signal/connections), I found them to be somewhat thin in the mid-range, and relatively light in the bass regions. I also noted that the quality of both the bass and the treble was superb, the bass with great speed/impact, detail and texture, and the treble detailed and airy, without being strident or fatiguing...Please understand, my reference points were the Sennheiser HD-650's, (until about 8 months ago), and then the Audeze LCD-2.2's, (pre-fazor), so that I had come to expect a relatively lush bass and lower to mid-mid-range...However, I was not terribly enamored with that mid-range...still a touch threadbare relative to MY personal preferences...(being a former French Horn player, I like to hear that lush horn timbre)...
So I elected to break the "C's" with pipe organ music...with limited effect after roughly a week at somewhat higher than normal listening levels...but then switched to Dub-step to utilize its more "insistent" low bass, and for the last couple of days, at significantly higher than normal listening levels...et voila...NOW the "C's" are beginning to come into their own...Now, the mid-range is still not quite so lush as with the HD-650's, or the "ever present" deep bass weight of the LCD 2.2's, however I recognize that these are voiced differently, and therefor the "C's" sonic qualities work wonderfully as an integrated whole...
I DO wonder how one might determine what is the highest "safe" level at which they can be driven, (at what frequencies), in order to "optimally" break them in, and what, if any additional sonic changes/improvements I might experience.
Yes, everyone's perception/expectations differ to some degree...however, I am interested in hearing about others' experiences regarding break-in of these cans...
