3,700 mAh Large-capacity Battery

The SP1000 AMP is equipped with a 3,700 mAh rechargeable battery to provide

9 hours of uninterrupted music playback.

– SP1000 AMP supports 9 hours of continuous unbalanced-output playback.

Perfect Unity

The black backing of the AMP represents shadows of the natural materials of the SP1000 and as the wavelengths of the sound splash in every direction, the reflected shadows express a divided silhouette.

The soft blue light surrounds the SP1000 volume wheel and accentuates the beautifully crafted crown pattern as the light shines upon it.

The precise angle of the wheel and the AMP surface, when combined together, has a functional space that does not interfere with the operation of the wheel and conveys the AMP status through the blue and red colours.

The SP1000 player locks to the amp, providing a simple and secure connection, giving you the feel of a single, united device.
