A tube rollers' delight, this sweet little amp comes with three pairs of differently-toned tubes.

Get ready for the lush life! If you’ve never owned a vacuum tube amp before, you’re in for a real treat. In brief, tubes have a lot more second harmonic distortion than solid-state transistors, and fewer high-order distortion products... What that actually sounds like inside your head is a superbly warm, luscious wash of tonal color in the music. The great advantage of an amp with this kind of coloration is that it makes ragged and low-fidelity recordings sound much better. This is a superb headphone amp choice for your older rock and jazz recordings, as well as for a lot of the more modern dance, hip-hop and remix tracks that sometimes have a tendency towards a harsh, sharp-edged timbre in the upper treble ranges. For headphones that lean towards the overly-bright or peaky-sounding, the Millett will also help lend a new sense of smoothness to their sound.
