The Little Dot MK III succeeds our Little Dot II++ by improving upon it in every possible way. Boasting the highest stability and sound quality yet, the sound-stage realism and imaging precision have improved dramatically over our previous amplifiers, and even at high volumes the Little Dot MK III delivers a smooth, non-fatiguing sound with no hint of dynamic compression or imaging fuzz. Of course the liquid warm midrange tube lovers expect is here in spades, balancing right in with a dynamic low-end and a sweet, airy treble. Tracking precision with low distortion is provided by an ALPS-16 potentiometer, and Rubycon, German WIMA and ERO capacitors ensure the internal circuitry is built with quality in mind.

The Little Dot MK III also adds in user-tweaking options such as two gain switches to delivery maximum compatibility with all your headphones, regardless of impedance or sensitivity. Also available for the very first time in a Little Dot amplifier, is an internal jumper to allow use with a wider range of driver tube-rolling, including the EF92, CV131, WE403A/B, GE5654, M8100, CV4010, EF95, 6JI as well as all equivalents to these vacuum tubes!

Power Cord Note: Little Dot amplifiers ships with a standard Type-B power cord (American 3-pin or U-ground) suitable for use in areas such as North America, Japan, Taiwan, etc. If your country's outlets use other power cord types (ex. Schuko) you will need to provide you own power cord. You likely have several spares around your home, as any standard power cord (like your computer's power cord) will work perfectly fine. We do apologize for any inconvenience!
