Little Dot MKIII Tube Headphone Amplifier

"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."

Standout Features:
• Delivers a smooth, non-fatiguing sound with no hint of dynamic compression or imaging fuzz
