Just sharing my experience. Speaking of Hijiri cable, conincidently I just loaned the million IC yesterday from my local dealer.
I am connecting both silver dart XLR and Hijiri RCA from my TAD CD player/DAC to preamp, so able to switch the preamp input and compare albeit is between XLR vs RCA.
Initial listening is that Hijiri is more fluid sounding with more rounded and seductive mid, silver dart soundstage depth sounds slightly better. But I am not sure how much the connectors impacting what I am listening.
