Little Dot MK3 MKIII Hi-Fi Vacuum Tube Headphone Amplifier Stereo Audio Preamp


The Little Dot MK III uses the same SEPP design found in our flagship MK IV headphone amplifier, which boasts extremely low distrotion and high stability. The front driver tubes are General Electric GE5654, and the rear power tubes are Soviet 6H6PI, the combiniation of which can deliver excellent power output as well as natural sound quality tube amplifiers are best known for. The potentiometer used is an ALPS-16 to deliver precise tracking with ultra-low distortion. Inside you'll find Rubycon filter capacitors, German ERO coupling capacitors, and FHIEMI-COM output capacitors matched with German WIMA to deliver dynamic bass, a liquid-smooth midrange, and a sweet top-end tube lovers are sure to enjoy.

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, 5654, M8100, CV4010, EF95, 6JI as well as all equivalents to these vacuum tubes!
