Replace LAT Coax cable between Bluesound and Oppo DAC


I am using a LAT Coax between Bluesound Node2 and Oppo 205 for DAC.  Using LAT Coax cable I got for free at a hifi show.  Is Coax or Optical the best connection?  Any point to buy a better cable?Thank you.

Get your hands on a bit of Vivanco KX-710 tv-coax, put a rca-plug in each end and you will have a reference cable. 
Nordost Silver Shadow. If you’re using the stock power cord I’d suggest switching that out as well on your Node. Both make a significant improvement. Oh, and your 205 deserves a better PC as well; I use a Nordost Vishnu on mine.

Don't buy anything unless you can audition it first. The effects of digital cables are very system-dependent. With excellent modern equipment, it's been my experience that the differences among SPDIF cables are slim to none.

What connection is better depends almost entirely on your source component and DAC. Again, you will have to listen to make a decision.
