Summary: I got one of these about 2 years ago. I chucked all my jewel cases and got my shelf space back. I love the random play and being able to ban disliked tracks. It survived a move and spending 8 months in storage (by the way, it remembered all the disc information that I had typed in.) Recommeded -- keep a computer listing of all your cds with title, artist, group, and slot number just in case. It also makes it easy to print out differently organized directories.
Summary: I needed a CD changer, and was deliberating between a 5 disc changer and one of the newer 300 disc changers. In the end I decided to go with the Sony CX-300 as it's a great bargain, and since it was a Sony like my receiver (STR DB-930) I could use my receiver's remote to view the disc titles. (just like the remote that comes with the more expensive CX-350) The unit isn't as tall as I expected, maybe twice the height of a normal CD player, though it is very deep (~18").
Summary: This is an excellent addition to my stereo system. Despite being a large unit, this 300 CD changer has saved me SO much space--I have said goodbye to jewel boxes forever. I love the grouping and 'hit list' features that allow you to arrange your discs in easily accessible and discernable categories. My one complaint--don't be fooled by the "CD Text" feature which claims to automatically enter data from 'equipped' discs.
