I donβt know about that statement of the i2s connection , could be simply because Rockna utilized this method more so then USB . My server has been utilized specifically for USB , itβs not just a port on a board though other manufacturers of servers and dacs have focused on USB more so then other digital connections, a good example I was just reading about is the Holo May KTE.
Going through cables and finally using Sablon Audio USB cable has significant sonic results over the other USB cables I have tried and the results especially with vocal timbre is uncanny , a believable more human sounding living presence with well recorded vocals other cables I experienced simply subtracted details like timbre , itβs a very fragile signal thatβs for sure.
This one area for me will be The test if this digital stack with Hub can reproduce this eye opening level of timbre. ,..I mentioned above whatβs up stream of the dac will make a significant difference , speaking for myself putting the Hub through this test will make or break my decision on the Hub.
