Dang it.

This product has been discontinued. Luckily, we have a great alternative in the SMSL H300 Headphone Amplifier.

The mighty mini desktop amp

The SMSL SH-6 is a desktop amplifier that packs incredible performance into a minimalistic user experience. With 2.6W x 2 of output power and THD+ as low as 0.00006%, it’s an ultra-clean and powerful budget amp that’s perfect for beginner audiophiles.

Incredible output power

The SH-6 provides an incredible 2.6W x2 of power at a 16Ω load and 1.3W x 2 at 32Ω. With power like this, you’ll be able to run even the most demanding of full-sized headphones without a problem.

Classic toggle switches

The SH-6’s user interface is as minimalistic as they come. A single potentiometer and a pair of silver toggle switches are all you need to enjoy your library all over again. 

Two-step gain switch

A two-step gain switch with a 15.5dB differential lets you accommodate a huge variety of headphones.

Built-in low-noise power supply

A built-in low-noise power supply keeps things tidy. There’s no need to connect an external adapter, so the SH-6 will fit in the most space-challenged of setups.

Ultra-low distortion

The SH-6’s precision feedback circuit boasts distortion as low as 0.00006%.
