Sony HDD Component System NAS-D55HD Junk The right channel buzzes. It works fine with headphones. The hard drive has around 1500 songs. Classical, jazz, mood music, Western music, Japanese music, etc. are included. Also, there is a switch on the back to stop the fan noise, which can be bothersome when listening at low volumes. The items for sale are the main unit and the dedicated speaker cords. The speaker cords are originally directly connected to the speakers, but this time it's just the cords. The cords are connected to different cords in some parts. CD playback and FM reception are both fine. Recording from CD to HDD is OK. Please consider carefully as this is a used item. Thank you.
