Little Dot MK I+ Portable Headphone Amps

The successor to the Little Dot MK I, the new Little Dot MK I+ takes advantage of American National Semiconductor’s newest offerings in ultra-low distortion circuit components: LME49710HA high fidelity operational amplifier and the LME49600 high performance current buffer. The new power supply consists of two 3.7V 700mA/h Lithium-Ion battery to provide up to 30 hours of high current, ultra-low distortion power to your headphones. Circuit stability and reliability over the previous Little Dot MK I has been markedly improved as well.

The Little Dot MK I+ also has exceptional compatibility with a wide variety of IEMs, earphones, and full-sized headphones due to its user-selectable three gain settings, as well as output current control via internal jumpers. When jumper caps are set in place, output current increases by 80%, dramatically improving dynamics, impact, and low frequency response with the trade-off of lower battery life.

There are two version of the Little Dot MK I+: the Normal Version and the Gold Version. The Normal version has a plastic housing and uses the LM4562 op-amp in the pre-amp section. The Gold Version has a metal chassis and uses dual LME49710HA in the pre-amp section.
