Yes I think maybe there is a bit of hype regarding CD transports in general although I think there certainly could be a difference between the very worst CDT and the best out there. Not seen a comparison between a whole range of CDT out there but I would suggest it would need at least 5 and a couple of regular CDP thrown in for good measure.
