The Sony CFDG 700CP Xplod boombox has the best sound I have ever heard from a portable. The unit has amazing bass and awesome biamplifier. The ability to play MP3 and connect to aux device like an Ipod is a very good addition. You won't be sorry..
I would like a backlight and the red woofer ring does reflect light if you put your hand up to the display to see the readout in the dark, though. The weight is also an issue-this thing is heavy-about 20lbs without batteries.
The ability to play MP3, Ipod, custom made CDs, tapes and great FM reception is this systems greatest strengths, The power behind this system is very impressive and it can get very, very loud without distortion.
