I used to have the same problem with McCormack Mod Squad CD-player. If I was running it without DAC everything was fine. The next thing I've done to get rid of that problem is I've bought a dedicated transport and feel happy still.
I've assumed that you would play successfully your CDs in the player itself with no DAC. If such thing will not take place, you should contact the manufacturer and explain the situation when you've sent your unit and the problem wasn't fixed.
