Best power/digital cords for C E C transports.

I Have an Electrocompaniet ECD-1 dac & recently purchased a used CEC TL-2x transport. I have a balanced MIT reference digital interconnect & am using a BMI EEL powercord.I also have the TL-2x well isolated,not a concern.

These cords sound great with my Cal Delta transport & ECD-1 combined,not with the TL-2x & ECD-1 combined.These cords also sounded great with my Cal Delta transport & Alpha dac.

Could it be the TL-2x does not have the proper synergy with my dac? Could the TL-2x need calibration?I would think the TL-2x should outperform my Delta. What cord combos are you using to get the best sound out of your digital separates? Might the digital rca connection sound better in this case?

I am not looking to spend for the very expensive cords unless great deals on used.I am also not into doing any mods on a unit that retailed for $3300.Thanks.
