Designed as an upgrade to standard computer and audio music server cables, the Hidden Treasure SATA Cable provides a real gain in musical performance. Mass storage devices such as a hard disc drive, optical drives and solid-state devices connect to the system mother board via SATA (Serial Advanced Technology Attachment). Much like the gains achieved with other high end audio cables, the SATA cable should not be overlooked. In fact, the data transmission via SATA operates at much higher speed than a USB and is therefore more susceptible to jitter and internal system noise. However, when using the Audience Hidden Treasure SATA cable in place of a generic SATA cable you can expect to hear more low level information due to the lower noise floor. By removing layers of grunge, the resulting sound is a solid night and day improvement. It is noticeably clearer, smoother and more analog like.
