I can't compare to the CKR9's (wish I could!), but for some reason I am not hearing the Titans as being either cold or warm, but just right. The bass and the highs seem to really balance things out and fill things out nicely for me. Switching over to the B3's now, the B3's seem cooler or thinner. Some of that must have to do with the much lesser bass, but also the highs seem dryer/thinner and I might even say harsher in comparison with the Titans. So to me the Titan1's sound warmer and fuller and also seem like a definite upgrade. But as with all things, ymmv!
I think the thing about the titans is that they are uncharacteristically a combination of both warm and cold sound. Just my opinion.
The low end on the Titan carries plenty of thump and puts plenty of weight on male vocals, making it so some can say that they have a warm sound. Once you get into the upper frequencies it's just the opposite. It does get a little cold, sharp, extended, and very detailed from what I hear.
I think that's why people are liking them so much, because it's like a combination of both.
