Thanks dude, finally a constructive response here, really appreciate for that!
Glad you appreciate a link to an old thread where the test files have long disappeared and not a single bit of proof is to be found. Have fun spending some cash and don't forget all the other cable types including Vovox USB cable and a proper Vovox Ethernet cable for the Kemper Remote. And just to be safe, you might want to consider 2 Vovox S/PDIF cables as well.
