Little Dot MKIII Tube Headphone Amplifier

Up for sale is my Little Dot MKIII, a fantastic tube headphone amp that’s perfect for audiophiles looking to elevate their listening experience. This Class-A SEPP OTL design delivers warm, detailed sound with that classic tube magic, making your headphones sing like never before. Key Features: • Tubes: Front: American GE5654; Back: Russian 6H6π for rich, authentic tube tone. • Inputs/Outputs: RCA input; 6.35mm (1/4”) headphone jack for direct amp use; RCA pre-out for integrating as a pre-amplifier in your setup. • Frequency Response: 12Hz - 100kHz (-1dB) for full-range audio fidelity. • Power Output: 350mW into 300/600Ω, 300mW into 120Ω, and 100mW into 32Ω – handles a wide range of headphones from low to high impedance (32Ω-600Ω). • Distortion: Super low THD+N at 0.15% (80mW into 300Ω) for clean, distortion-free playback. • Build Quality: Premium components including German ERO coupling capacitors, WIMA tuning caps, Japanese ALPS-16 potentiometer, RUBYCON filters, and CHIEMI-COM output caps. Housed in a sturdy aluminum chassis. • Dimensions & Weight: Compact at 270 x 175 x 123mm, weighs 3kg – easy to place on your desk without taking up too much space. • Power: 30W consumption, standard AC input. I’ve used this lightly in a smoke-free home, and it’s in excellent working condition with no issues – tubes are still strong and sound amazing. Great for pairing with high-end cans like Sennheiser HD6xx (see my other post) or planar magnetics. Comes with original accessories and a pair of Voskhod 6J1P-EV tubes which can be swapped in for a different sound profile.
