I'd expect that you'll be receiving a variety of responses, including assertions that your system and/or your ears and those of the other listeners aren't "resolving enough," the recordings weren't good enough, the y-adapters and/or the doubled cables and/or loads that were applied to the CD player resulted in a loss of resolution (although based on the impedances that are involved **in this particular case** I doubt that was a problem), etc, etc.
IMO what you've mainly determined is that your particular hardware is not particularly sensitive to the differences between the two particular cables, in the lengths that you require. And that does not necessarily have anything to do with the musical resolution of the system.
Also, I think you'll find this thread to be of interest.
I assume, btw, that the test with the turntable was done by changing cables rather than with a y-adapter, as one of the two phono inputs on your preamp is for low output cartridges and the other is for high output cartridges.
