Is Digital Optical the best quality connection you can use to connect your DVD to receiver? If not what is, I know HDMI is supposed to be great but most receiver don't have that connection and if they do it is a pass through.
Different schools of thought on that one. You can do digital coaxial or optical, there's even 6 channel analog. If you currently have a digital optical connection just use it. If you dont like the way it sounds, then try a different one.
