Power on confirmed. Sound from the speakers is also OK, but the CD tray does not come out. I was unable to confirm if it can play CDs. I was using it to play music by saving music data via the USB port. The sound is very good. I still like it. It was made in 2006. The original price was about 60,000 yen. - Brand: SONY - Model Name: NAS-D50HD - Remote Control: Included - Number of Speakers: 2 - Color: White - Functions: HDD audio system, digital amplifier The box is not included.
