I just did an exhaustive 3 month long test of the best wireworld, cardas ,shunyata, audence and a couple other brands including zenwave. I had power cables , speaker cables , interconnects from all the brands and tried every combination i could. And for interconnects nothing beat the dsr and d4/d5 interconnects. The scr-11/14 speaker cables were winners. I had the pcr-11 power cable which is also great. I wasnt able to test the silver ribbon speaker or power cables but the interconnect was a true stand out of the bunch. I had everything from shunyata alpha v2 to wireworld platinum 8 here is how i ended up.
wireworld platinum usb to hqplayer , shunyata sigma usb to dac , zenwave dsr dac to pre , zenwave d5 pre to amp, zenwave scr-11 amp to speaker , zenwave pcr-11 on my amp, shunyata delta v2 power for the dac , shunyata delta alpha v2 for the preamp.
i am still waiting for the zenwave silver ribbon power cable and speaker cables to test. And im still playing with the zenwave dsr/d4/d5 in the pre to amp position.
out of all the cables i tested the zenwave stuff was by far the most impressive. Especially the d4/d5 and dsr interconnects ive never herd silver sound this good it is literally everything i wanted from copper and everything i wanted from silver combined the tonality , neutrality , fullness , slight warmth, snap , impact , quickness was like nothing else i tried. And as for the scr-11/14 speaker cables they had more clarity then any of the copper speaker cable i tested almost as good as silver but with better tonality then i had herd from the silver cables i had available.
I typed this on my phone so please bare with me.
