i jus need to know, would the m200 kill the W4/R?
i watched the KEF promo video, sleek looking...dual dynamic drivers.. this should be my end-all iem??
Yup, I said that in the other thread, I love these out of my Fostex HPA8c. I try not to use anything else except that.
I'm keeping an eye on this thread for the M500 impressions. Unless someone can seriously sway me on the M200s of course, I'm set with in ears for the time being. But I need a complimentary headphone for my M-100s.
Only negative I had with them...besides not loving the looks...is that these things are warm, more so than other on-ears, which have a little room for air. I described on the other thread: These are like placing pancakes on your ears. Sure, they are super soft. But, at least for me, they heated up instantly! Not like other on-ears that give you a little time before needing a break.
The M200's isolate very well. Better than most single-flange rubber eartips, IMO.
Am I the only one who thinks the M200 are entirely too weighted to the upper bass, though? I've compared them not just to my other IEMs (ADDIEM, Vi-Sang R-02, Ety ER-4), but also my full-sized cans (Mad Dog 3.0, Denon D2000, Senn 580), my nearfield system (Soundfield Audio Monitor 1's), and my reference system (Pioneer EX - basically, TAD-lite - front three, KEF R-series surround, KEF Q-series rear, multisubs, Anthem Room Correction). There's just too much tilt in the FR.
I think you misunderstood my comment. Though I'm not sure, as your response isn't terribly comprehensible.
What I wrote was that the FR is tilted too much in favor of the upper bass, i.e. downwards-sloping, for my taste. I made no comment on the subbass.
A song that shows off the issue well is "How to Disappear Completely" off of Radiohead's Kid A album.
And actually I bet the output capability at 20Hz is quite high, due to pressure vessel gain. (Imagine a room that's a little longer than it is wide, with a woofer as the whole front wall.) But it's also irrelevant because frequencies that low are perceived by the bones of the and chest, not the receptors inside the ear. Those of us with home systems capable of playing such frequencies at high SPL with low distortion understand that.
And the source is entirely irrelevant to my comments. Suffice it to say that I've tried them with several, including dedicated high-fidelity headphone amps with known flat FR and low source impedance. And without equalization.
