DENON CD player DCD-1630G equipped with high-quality PCM audio technology. Basic operation has been confirmed. CD opening and closing are also good. Since I don't have headphones, I've connected it to a guitar amp to check the sound output (images 11-12). The closing of the opening at the bottom of the main unit is not smooth. As with other sellers, there seem to be some discs that cannot be read (e.g., CD-R). Also, some CDs from the last few years may not play. Please consider this before purchasing. One-owner item. - Brand: DENON - Model: DCD-1630G - Digital Audio Source: COMPAC DISK DIGITAL AUDIO
