Hi all,

I am new to the Sound Bar LCD TV world so please bear with me.

I have recently purchased the POLK Sound Bar IHT and have it connected directly to my Toshiba 46XV645U using the supplied audio cable. My question is two fold: (1) Is it worth upgrading to digital audio cables (AC3) I beleive.
(2) Should I connect the audio to my Brighthouse HD cable box instead of the TV itself. I only have a DVD player in the mix which I plan on upgrading to Blue Ray sometime this month
