DarkVoice 336SE OTL Headphone Amp

Headphone amplifiers come in a variety of circuit designs, each with its own advantages and drawbacks, but there’s one main determining faction: distortion level. Credited with having the lowest possible distortion, Output Transformer-Less (OTL) headphone amps cut out a key part of conventional amplifier design to eliminate a major cause of audible distortion. Without the Output Transformer, you get clearer sound, powered tubes, and overall better amplification. Arriving with an OTL design, the DarkVoice 335SE OTL Headphone Amp gives you a blank backdrop to properly broadcast your favorite jams.

While you can’t very well drag your headphone rig into the middle of any empty NFL stadium or get air dropped onto a deserted island, music always sounds better surrounded by complete nothingness. With the DarkVoice, the deep blackness lets you notice every note like never before, adding a dimension of accuracy that’s usually cloaked in distortion. To fill out the space, the 335SE puts out warm mids (courtesy of the tubes), analytically detailed highs, and fully transparent bass. By pairing together tube warmth and OTL circuit design, this amplifier produces the cleanest warmth we’ve come across.

As solid as a rock, every visible surface on the DarkVoice 336SE is either glass or anodized black metal. Rounded out with gold-plated RCA connectors, a metal name plate, a high quality potentiometer, and a power supply enclosure, this heavy duty piece of equipment- weighing in at 11 lbs- feels as solid as it sounds.

If you’re still looking for more function, the DarkVoice 336SE OTL Headphone Amp is capable of powering headphones with up to 600 Ohms of magnetic resistance, as well as operating as a tube-based pre-amp for your speaker system. When you want great sound without going over budget, use the 336SE as a headphone amplifier and speaker pre-amp to hit two birds
