Looking for a reasonably priced good quality interconnect

This may be a dumb question, but since both my optical cable and coax cable are plugged into the DAC does the burn in time count for both cables at the same time when I have music or pink noise playing?
In other words, will I be getting the benefit of coax burn in when I have the signal actually sounding in the optical input?

rvpiano - According to Mike at Morrow Audio, what matters is that there is signal flow into the outbound end of the cable.  IOW, as long as there is signal flow into each cable, you are burning them in.  I have no idea if optical cables even need burn-in.  Intuitively, I would think they do not.  But I am sure others who know more about this than me will chime in...

I like the Kimber PMJ's . 'Been using them, in addition to Audioquest,  on various sources for years.

Thank you, bondmanp.
I was hoping that was the case.

No need to burn in optical cables
