That's weird as even very old dvd or cd rom drives transports in computers send it, as you'll see HDCD come up in the bottom left corner of Widows Media Player that it's a HDCD disc being played.
They must have done something pretty weird with the McCormack to needlessly filter it out.
PS: As Kalman Rubinson of Stereophile states here it must have been defective. Or maybe it could have been a bad digital link cable from it to the dac, maybe not being 75ohm
