Improve Your Listening Experience

Instead of a single cheap tube that gives off muddled sound, the Little Dot MKIII features four tubes: two dedicated input tubes and two dedicated output tubes. Letting your left and right audio channels enter through separate RCA ports and pass through channel specific input and output tubes before joining up at the headphone jack, you get a clear signal on both sides with little to no crossover. Encased in solid aluminum, this headphone amp features solid metal construction throughout the entire device. And in case you’re also looking for a partner for your speakers, the Little Dot MKIII Headphone Amplifier can also be used as a preamp via the RCA outputs on the back.

Note: At checkout, choose the MKIII (base price) or the MKIII SE (+ $260).

About the MKIII SE

A sequel to the acclaimed Little Dot MKIII, the MKIII SE hybrid tube headphone amplifier features a streamlined design, a new balanced headphone port, and significantly more power. The tube pre-amp stage delivers a lush midrange and natural soundstage reproduction, while the discrete transistor output stage—with a fully symmetrical, pure Class-A circuit—produces a powerful, detailed bass response. Both fully balanced and single-ended outputs are supported. And like its predecessor, the MKIII SE can be paired with a variety of different tubes to achieve your desired sound signature.
