The HX-D77 is a large stereo system from JVC, aimed at consumers that want the ultimate system to play their CDs, DVDs, and even computer media. Aesthetically however the HX-D77 appears targeted toward a younger audience, appealing to the 'monster truck' image of bigger and badder is better. Pumping out a total of 540W, the HXD77J features a 5-disc changer, a radio tuner, and a USB connection, allowing the unit to handle DVD-Video, digitally encoded music in MP3 and WMA format, and JPEG images as well as the almost forgotten standard medium of choice: the CD.
