A/Bing the CLR100 and COR150... I'm pretty sure they're the same driver. The different housing with additional venting gives the COR a massive bass boost, but otherwise they have just about identical frequency response to my ears. I use nearly the exact same parametric EQ settings to get them to sound flat to me (with the exception of the COR's extra bass). I think any discrepancies in the exact frequencies of the upper mid/treble peaks is due to different insertion depth from different fit of the two housings. Like I said, they're nearly identical in any case, and I cut the peaks by the same amount to get the same result. However, I think the COR is more reverbrant and smeared, especially in the bass, and this gives it a narrower soundstage to my ears. This combined with the facts that the CLR has better driver matching and easier/more comfortable fit for my ears, and if I twist them just right after insertion, they have nearly as much bass as (but much tighter than) the COR, makes them the clear winners to me. They just sound much more refined and cleaner. They're not TOO far behind my CKN70s in technical ability, but better driver matching in the 70s and their unbelievably quick laser precision across the entire frequency spectrum means they're in no danger of being replaced by the CLR100. The COR150 might be kind of redundant, though, and I might end up getting rid of them.
EDIT: The soundstage on the CKN70 is so much bigger and more immersive it's ridiculous. These are clearly in another league versus the CLR100. Even so, the CLR punches far above its weight, and I'd say it's much more capable than the similarly priced Philips SHE3590. The Philips *might* sound better without EQ, but its treble is very peaky, so it sounds oddly comb-filtered, and its soundstage is quite narrow.
