Thank you for viewing. Everything in the photos is included. ELEGIANT DC 9V-24V compatible multi-mode power stereo amplifier. ○ Included: 2 power adapters (images 5, 6, 7, 8), connection cable, instruction manual ○ Condition: Used You can compare the sound of the two adapters. With the DC24V 2.5A adapter, the sound image becomes clear like a different device, and you can feel the sound pressure. I compared it with the Shin-san-do's Sokei model, but the ELEGIANT is a bit more brilliant in sound. However, when the power is turned on, Chinese music plays for a few seconds.
