Little Dot MK III Tube Headphone Amplifier / Pre-amplifier

Post by sword_yang »

The LittleDot 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, and all the components in this circuit are famous and reliable. It has been once praised as “Lucky Product” by Stereophile magazine. 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!
