I believe they are part of the supposed "bass-light" ones but I don't remember for sure. I actually think they were as bright as the CD3000, though my biggest problem with the R10's treble was sibilance. I actually like the Qualia better so far, they have a really nice soundstage its huge but remains remarkably cohesive and they have really precise imaging. The midrange is a bit sterile though, and while they have nice tight bass it's nowhere near as deep or impactful as the L3000s is.
