Little Dot MKIII MK3 GE 5654 X2 6H6PI X2 Headphone Tube Amplifier + Pre-Amplifier 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.
