Looking to connect a Hitachi 50HB6T72U TV to Samsung HW-J550 Soundbar. The Hitachi looks like it has a SPDIF (Optical Out) Connection and the Soundbar has an Optical input. But what is the exact converter and cables I need?? Or what is the best way to connect these two devices for optimum sound quality??Providing links to where I can buy them would be great. Looking online and getting very confused. Thank you for any help in advance
