What is astounding about The Little Dot MK I is the ultra low noise and distortion specs., Total Harmonic Distortion is rated at 0.001% for a 32 ohm load running at 100 mW.
The Little Dot MK I is the successor to the highly-regarded Little Dot Micro+ portable headphone amplifier and wins its predecessor in every aspect of sound quality imaginable. Employing the much heralded LM4564 op-amp (placed in socket) along-side the Texas Instrument's TPA6120 amplifier chip to make up an exceptional circuit design, The Little Dot MK I provides audiophile sound-quality in a small amplifier footprint. Powered by an integrated, rechargeable Lithium-Ion battery, The Little Dot MK I frees provides up to 20 hours of playback time per charge!
The construction is impeccable, the outer case made of aluminium with a distinctive two tone finish making it also very stylish.
