To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This is a nice compact and well built unit. That met my object of providing a short optical run from my Cisco 8-port router to my home theater PC. (HTPC) I separately order a compatible Cisco transceiver and 1 meter optical cable. From the Media Converter I ran a short high quality ethernet cable to the JCAT NET XE card in the HTPC. Not a profound increase in sound quality but a noticeable improvement. Quick and easy installation. I'd recommend this for audiophile use.
