I recently bought a Pansonic 50" Plasma. It has an optical out I run to my 990.
I also have a digital coxial cable running from my direct TV box to the 990.
Now here is what is strange, when listening to audio via the coaxial cable from the direct tv box, everything sounds mudled, but when I switch to the Pany's optical cable everything sound much cleaner.
Is optical that much better ?
