Up for your consideration is this Qsonix music server with over 18k titles loaded and ready to play. this is the largest unit at 2TB with a touch screen 15 inch display drag and drop play lists. the unit works perfectly and has amazing sound quality. Included is a portable backup unit, 2 additional new replacement hard drives with operating system installed, remote control, operating manual and all original boxes and packaging. all album art work and info is displayed on screen with lots of adjustability. Qsonix format is no longer supported on line but you can easily load music with the CD drive and its a great way to arrange long listening sessions and organize your music for safe storage.Check my feedback and buy with confidence.
