Query: Sound Quality is extremely good

amazon DOES NOT SUPPLY CLOSED CAPTIONING WITH ITS TV SERIES.For that reason, clear and understandable voice quality is essential to enjoying a purchased series.Seasons one and two are about 95% understandable. Season 3, to my ears, is about 90%.Also, of course, the mix of characters and situations produces compelling drama every day of the week.I have good hearing in one ear, so, Amazon, I manage without closed captioning. I *do* avoid buying TV series that have poor sound quality.Now if only people who are deaf in both ears could "hear" the series, with closed captioning, all would be fine.
