Fsmithjack,
Relax, just bring your Tellurium cable to your Bricasti dealer and see if it works with his demo unit. If it does, he can just replace your M1 with a new one and you should check that one before you leave the store. If it doesn't, connect the Tellurium to another brand of dac in the store and if that works, it will show that the cable is not the problem.
