I don't believe it.
Believe it, or not. It's my experience as well. But I wonder if he meant that he was using a computer CD player? What I believe he may have meant, and correct me if I'm wrong Pardales, was comparing the music from CEC transport + Dodson combo, to the same music stored on a Hard Drive in WAV or lossless format going via USB, clocked and converted by the Waveterminal, and then on to the same Dodson DAC to be reclocked. It has been my experience with my own DAC and Transport (both Muse) that I cannot tell the difference from a lossless hard-drive version vs my transport. Never bothered trying the transport in the computer.
