Cable dB difference? (DAC to amp)

[D Tilley]

Any experience with difference in sound level with different cables between DAC and AMPs?

Have Crimson music wire (12') from DAC to Amp and need to add a parallel pair from a different source (ordered Oppo 95) to Amp.

Received a pair of Mogami Gold (12') for 2nd source--

Any predictions? Should I expect similar voltage/resistance/dB level from the Crimson and Mogami? Guess I should A/B both cables with current DAC (and sound-level meter) before OPPO arrives. Would do this anyway, for Sound Quality, but I'm OWT (old, with tinnitus).

 

Thank You
