An Amplifier module designed specifically for the SP1000 to drive full-sized, high-impedance headphones.

The SP1000 AMP offers High Gain output of 10Vrms for Balanced output and 6.2Vrms for Unbalanced output. The modular design fits perfectly with your SP1000. The SP1000 AMP adds more power and performance for your SP1000.

The AMP has been designed to protect your hearing.  It adjusts the output every time the AMP is turned on and/or your headphone is disconnected from the AMP.  The AMP can be turned on and off easily from the quick settings menu. Gain can be adjusted in the full settings menu.

The SP1000 AMP is equipped with a 3,700mAh rechargeable battery to provide 9 hours of uninterrupted music playback. – SP1000 AMP supports 9 hours of continuous unbalanced-output playback.

The SP1000 AMP offers greater portability when paired with the SP1000 player with its optimal design and fit.

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 colors.

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