Swissonic HAD-1

I only wanted a headphone amplifier...

I only wanted a headphone amplifier, but got so much more.

As a headphone amp, it puts in a very creditable performance at a very reasonable price. I'm using it to drive a pair of AKG K-712 headphones and I'm more than satisfied with the sound.

It also has USB in/out, S/PDIFF in/out, and phono in/out, built into a stylish and rugged metal box. My only slight criticism is that it requires a wall-wart power supply (included) rather than mains power.

Extremely versatile device with great build quality.

Works flawless from the start on

Pretty solid case, has some weight to it, so it doesn't fly away

Wonderful DAC/AMP

it can run 250 ohms headphone smoothly

Finally

An affordable piece of hardware to run 250 Ohm headphones smoothly. Also tons of inputs and outputs (not tested, used only USB for now).
