Whats the best way to hook up your audio for the HD A1. Currently Im using coaxial and I know that you guys knows whats best. I learn a lot in this forum and probably you can help me decide on how should I hook up my audio for my HD A1. I have a Denon 1804 which is old and SXRD KDS50". Im very happy to buy the Toshiba. Now I want some good quality sound. Thanks!
