I tried the DH Labs and RAL i2s cables. At first I thought the RAL sounded better, but went back months later and did some extended listening switching back and forth between the two, which is easy and can be done quickly since my server and DAC both have 2 i2s connections. I couldn't tell any difference between the two. I chalked up my initial impressions to confirmation bias. I'd get the DH Labs cable.
