I have a Bel Canto Dac and occasionally have a similar issue when switching cables or powering everything down. Try waiting for a few minutes for the BC to lock onto the signal. If no go, then try powering down the trans and unplugging the BC and repowering one then the other, then giving it a few minutes to lock after starting the CD. Still no go power down then re-power in reverse order. In each case remove the cd before powering down and insert after both are up. I can't remember which combination works, no idea why, but once the BC is locked in everything runs fine until the next time the units are unplugged.
Hope this helps and sorry I could not remember the combo that actually worked for me.
