It should open up at about 100h mark. It needs a little time to settle in. It's quaite normal behavior for new equipment to go through sometimes weird periods during breaking time. I would not worry to much about Mac, it will get only better from now on (like wine).
Musical Fidelity tube buffer might be in fault here but it is only my speculation. It wouldn't hurt to remove it temporarily from the system to evaluate its beneficial properties ......,or its negative effect on the overall sound quality. From mine expirience, unnecessary components in the system rob the detail, clarity and most importantly transparency. It is just like throwing in the signal path extra caps, resistors, boards, power supplies and cables. Less components between the source and the speakers the better. I am not saying that it is your case but it is just a thought.
So try that and give your nice brand new Mac some time to reward you with sound you are seeking for.
& not to worry, I can't sleep anyways.
