Description Description

The Little Dot MK III is a SEPP (single-ended push pull) OTL design operating in Class-A. The high voltage swing is ideal for powering high impedance headphones. 

Even at high volumes the Little Dot MK III delivers a smooth, non-fatiguing sound with no hint of dynamic compression or imaging fuzz. The liquid midrange vacuum tube lovers expect is here in spades, and the balance between an impactful low-end with a sweet, airy treble provides a reference quality sound. 

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 gain controls to provide maximum compatibility with all your headphones, regardless of impedance or sensitivity. 

Internal jumpers allow a wide range of driver tube-rolling options including the EF92, CV131, WE403A/B, GE5654, M8100, CV4010, EF95, 6JI as well as all equivalents to these vacuum tubes!
