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.
