The founder introducing the cable on their forum [1]: "Why did I introduce new models? First and most important reason for me is always better sound. Second reason is compatibility and ease of installation. JCAT HD SATA Cable offers much better sound quality compared to discontinued JCAT SATA v2. It can be used with any SATA drives, but It sounds best with music library HDDs. JCAT Reference SATA Cable is in a completely different league: much better resolution, dynamics. Darker, more natural tone. It can be used with all SATA drives, but it's best to have it on OS drive. I personally use the Reference on OS drive and the HD Cable on my media library HDD. Let me know if you have any questions. BR, Marcin" [1] http://jplay.eu/forum/index.php?/topic/2457-jcat-reference-sata-cable/ http://jplay.eu/forum/index.php?/topic/2457-jcat-reference-s...
