Recently installed an upgraded sound system in our boat. Changed out to bigger, and added more JL marine speakers, high-end marine Alpine head unit and amp. The former unit is going into one of the kids trucks. What an amazing difference in sound quality on this unit. Even my Elvis and Billy Joel sounds like they just recorded their tunes on modern digital equipment. I missed the vinyl days when ya spun a tune or two, sit at the record player and read the album cover and inside pages while the music played. But I can live with it with Sat radio, CD's and iPods. Wife just plugs her phone it to the head unit, kids hit Aux and the boats TV's play through it too. It's all come so far,, and evidently moving ahead. Microsoft just announced Windows 8 will not support burning nor playing CD's according to * Fox Business news. Now that stinks. Still like the quick access and sound of a CD. I had read sometime back, that CD's were a long ways off because they hadn't figured out a way to get the CD 100% flat for proper recording. An engineer with 3M read the same story and went to 3M company management and asked for some development money to find a way to produce a 100% flat CD. 3M is in the flat products business if ya think about it. Their stuff is always good, and they soon figured out a way to do it. 3M then patented the process, and they get a royalty on every CD produced today according to the book "In search of Excellence".
