Here is my first day experience with e-q7. I find the instruments very well presented, clear and laid back, very natural. I hear sound I didn't notice from my CK100. But when it comes to female vocal, which I listen most, I can't handle the sound. The vocal is too focused and not relaxed enough. Compared with the well presented instruments the vocal sounds like it doesn't fit into the music. Too focused to the centre, like the sound is coming from a very tiny point instead of someone actually singing. I don't know if burn-in will improve it but it seems that CK100 is more to my liking when it comes to vocal. The instrument presentation is certainly better, with sound stage and positioning more similar to TF10 Pro. I tried it directly on my N97 and through my new RSA Black Bird, but this "signature" sound (if it was intended by the designers) appears on 2 sets of sources. With or without my SR 71A, it seems that CK100 is still my favourite (and in my own opinion beats E-Q7). However I must admit that the eQ-7 has better bass. The bass of eQ7 is clean and tight, but in terms of deepness it still cannot rival CK100 when both are properly amped. If CK100 is connected directly whithout amp, its bass impact is indeed too weak (but the depth is still there). On the other hand eQ-7 gives reasonable bass even directly from my mobile phone. Kudos to eQ-7 for this one. I listened to a few acts from operas and true, eQ-7 is no match to CK100 in terms of treble.
All in all this is a topic of personal preference. When I say things about the vocal maybe that is because I have got used to the "colored" mid range of CK100 so much that I haven't given a fair review of the eQ-7. Plus the eQ-7 has not been run-in at all. Really hope these things would improve with time, coz I find the mid-range details quite good on eQ-7 - would be great to see improvement on the rest of the specctrum.
