gentlemen:
i have tried the audioquest jaguar and i have owned the cardas golden cross, the cardas golden hex 5 c, the quadlink and the twin link.
those cables are unbalanced. in the case of audioquest, too much upper midrange and treble energy.
in the case of the cardas, a bit forward in the upper midrange.
the audioquest sounded like there was some silver in the cable, perhaps all silver or silver coated copper.
the cardas is a copper cable.
right now the dcca interconnect and sunny cable technology interconnect seem to work for me.
thanks for the suggestions.
