A+CD+Player

While shopping for my first CD player, I was able to decipher most of the technicalese on the promotional signs. One designation had me puzzled, though, so I called over a salesperson and asked,:- "That means", he said, :- "**That this machine will read the digital information that is encoded on CDs and convert it into an audio signal - that is, into music."**
 * A CD Player**
 * "What does 'hybrid pulse D/A converter' mean?"**

So I remarked **"In other words this CD player plays CDs.**"


 * "Exactly.**" Was his response

Why oh why do they have to endeavor in impressing people with gobbledygook
