Tsugury - According this article they tested cables with device (Bel Canto DAC2) that completely (over 100dB rejection) rejects jitter. Bel Canto DAC2 is based on AD1896 - same upsampler used in Benchmark DAC1. Benchmark tested DAC1 with about thousand feet of cat5 cable instead of coax and could not tell the difference http://www.posthorn.com/Bench_5.html
Mentioned in sixmoon article modern dual PLLs used in CDPs don't even come close to rejection of AD1896. It would be nice to read article that makes sens - test with regular oversampling DAC or NOS DAC where good cables are needed (but not asynchronous upsampling jitter rejecting DAC).
