for clarification, the system sounds fantastic with well recorded CDs --- better with the more revealing CD player but still excellent with the less revealing player. With CDs that have typical recording quality again the system approaches sounding excellent with either CD player (slightly better with the more expensive revealing player.. but quite close and still very, very nice sounding) The issue arises when the CD is recorded with digititus, brightness --- typical of a good subset of the CDs i like to listen to. With these CDs the revealing player sounds biting, harsh and "lets through everything." Through the less revealing player, these CDs sound much better. Seemingly, the Creek (the less revealing player) presumably "rounds off" (adds coloration?) makes more smooth the digititus and makes quite listenable these CDs. The more revealing (less colored... more neutral?) CD player renders these CDs as they are... harsh and biting. So... yes it is the nature of these recordings to be harsh. This is largely why so many prefer analog over digital --- because much redbook digital is poorly recorded.
Based on this, I assert that coloration --- a component asserting its own character --- is not always bad and that neutrality is not always the best.
Thus, for digital playback... revealing may not be that desirable.
