While i was looking for a cheap way to switch between 2 coax someone suggested that i could use a RCA swith (my cables are super short).
Since i had a pair of "quality" rca cables (both are independant) i replaced the coax from my Pi hat to my DAC with a one this RCA.
It probably degraded the sound but i took no notice (i had no way to compare) , but then i fired the monumental "rider of the storm" which is in 192khz (not my deed this is what the Russian distribute) and it was mostly noise (you could still somewhat recognize the song) .
So it seems that rca can more or less carry low bandwidth digital signals (Genesis a trick of the tail in 96 was getting through) but totally failt at 192.
So digital cables do matter, now since a faulty digital signal is unusable cables for digital transmission may have a binary quality instead of a constinuous one. Either the signal goes thought and error correction reconstruct the initial signal or not. So situation is very different from the case of an analogue signal.
Since Coax was designed for Video which require way more bandwidth than audio, it is probably the case than any low grade coax can carry any reasonnable high definition audio (<= 192 khz, i have nothing beyond and don t plan to get any 784 // why not 778 // or 384 khz pcm).
Anyway more information would be welcome, rca work fine with 44khz and seems ok with 96khz but totally fail at 192khz.
