Did you try swapping the CDR into the DVD player and the original in the 508 ? That would ensure that the 508 was not being compromised by having to play a CDR. Ideally the comparison should use two original CDs.
Also what recording were you using ? Many pop/rock CDs are terribly recorded and will not bring out the best in the stereo.
Finally I have to say that I have long suspected what you report. I have favourably compared my Marantz CD67SE to an expensive Meridian player and heard only minute differences.
I concluded that digital sources are not worth more than 1/2 the cost of the amp or speakers, unlike turntables. Of course there are many who post here who prefer high end players ... perhaps their system is much better (and more expensive) than mine.
I'd be interested to hear more details of your test.
