Well, I would say that it's hard to push the cd3k to its limits...I'm not even sure that LT1363 was achieving that. And yes, after listening to it for a while, all the other opamps felt slow and bloated in comparison.
Its very high slew rate allows to pick up any tiny minute detail other opamps completely overlook. But the cd3k would be fatiguing due to all that resolution, when the t50rp always sounds laid back, but still very detailed...but in its own way. Those 2 phones are using 2 different technologies, to sum up I'd say that the cd3k is very fast and fatiguing and the t50rp laid back and natural sounding. The cd3k doesn't sound natural by any stretch of the imagination.
Someone said that the cd3k SS felt like a cocoon w/ its stunning 3D SS, I would say that my modded t50rp is the same...but not cavernous whatsoever(the biggest drawback of the cd3k to my ears) and even wider/deeper. This phone sounds amazingly natural, and those mids ahhhhh!
PS: listening to some techstep DNB as I'm typing this, this phone sounds too natural to make fast electronic music sound good IMO. Its goal is to sound true to life, but there's nothing natural sounding about a grossly distorted whiney bass line.
