Image: Little Dot MK VII+ Balanced Headphone Amplifier

Description: The Little Dot MK VII+ is a fully balanced, dual-mono headphone amplifier with single-ended compatibility. The circuit is composed of four independent channels with LME49710HA pre-stage and discrete BD139/BD140 transistor output stage. The four independent channels are fed by dual double-wound toroidal transformers with double rectification and four independent regulators which constitute a true “dual-mono” architecture. The input and output XLR jacks are Swiss-made locking Neutrik for superior conductivity and durability. The input RCA jacks are premium American CMC and the 6.35mm output headphone port is also a locking Neutrik jack. The volume control is a Japanese ALPS potentiometer for exceptional tracking and smooth rotation. Premium hand-selected resistors are used throughout the circuit alongside German WIMA / CHEMI-COM capacitors. The Little Dot MK VII+ is an OCL (output capacitor-less) design which provides an unmatched level of sound purity as components in the signal path are minimized to reduce distortion and imparting color to the sound. Extremely low output impedance and high damping factor coupled with immense power output ensures iron control of any headphone driver. The Little Dot MK VII+ delivers an unmatched level of transparency with unbound dynamic range, lightening quick transient response, and thunderous low frequency impact.
