Blue laser in CDP?


Just wanted to mention in a recent article I read that blue lasers can read much higher density discs and seemd to have better quality than red. Don't know if they are used in DVD players now or they could be the next big improvement in digital.

My Electrocompaniet EMC-1 MK II emits a blue light inside the cd transport while playing, but I don't know if it's from a blue laser.
Yes, YBA cd players - CD integra, CD3, CD2 and their flapship CD1 are all using blue laser but comes with only 18bit converter.
