I have Xfinity and find the sound quality so mushy that dialogue, particularly if in a foreign accent, is indecipherable. I thought that it was the speaker in the TV, so I connected the sound out of the TV to an amplifier that feeds perfectly adequate bookshelf speakers. Still the voices are mushy. While I am old enough to need a hearing aid, I don't think it's my hearing. I have no problem with voices in real life, or on CDs or over the radio in my car. Do others have a problem with the sound quality over cable? Is Verizon better than Xfinity in that regard? Is a special speaker the answer? It is possibly the circuitry in the TV that is at fault? I have a Samsung plasma, the picture quality of which is fabulous. I'd hate to give it up. Thoughts? Recommendations?
