Best thing to do is upgrade your digital wire and see what happens and use better tubes in the CAL Alpha DAC. Make sure the DAC is isolated from vibration also. These are inexpense options to try first. Borrow some digital cables from your local dealer or buddies. Next, sell the Alpha for a late model Audio Logic DAC 34 that has the upgraded 24/96 chip set in it. You can find them for around $1000 or less. It simply outperforms the CAL and the designer is available for upgrades.
