Features: The Little Dot LD1+ 6CQ6 is specifically designed and optimized for driving low impedance headphones that require high current to perform to their full potential. Depending on how the switches are configured, three different families of vacuum tubes can be used (EF95, EF92, and 408A). With two gain settings and DIP switches for vacuum tube rolling, the Little Dot I+ offers versatility and incredible sound quality in a tiny footprint! Specifications: Input:Gold-Plated Unbalanced Phono...

Features: The Little Dot LD1+ WE408A is a hybrid transistor-vacuum tube headphone amplifier, which combines the smooth, musical sound of tubes with the high output current of transistors. The vacuum tube stage is run in Class-A, the MC33078 operational amplifier (socketed) provides voltage amplification, and BD139/BD140 transistors serve as output buffers. Specifications: Input:Gold-Plated Unbalanced Phono (RCA) Jacks Output:1/4" Gold-Plated Stereo Headphone out Tube:408A X2 Frequency Response:...

Features: The Little Dot MK4 WE403A 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, GE5654, M8100, CV4010, EF95, 6JI as well as all equivalents, derivatives, and direct replacements to these vacuum tubes!...

Features: The Little Dot MK6+ is our flagship headphone amplifier/pre-amplifier in the Little Dot MK-series. A fully balanced architecture, the Little Dot MK VI+ has exceptional dynamic range and can produce clean amplitudes of 70Vp-p into 120 ohms! The balanced Class-A SEPP (single-ended push pull) OCL (output capacitor-less) circuit topology delivers rich tonality and brute force clean power for maximum dynamics and low frequency impact. Specifications: Available in either Black (default) or...

Features: Little Dot MK9 is that uses a electronic tube as a headphone amplifier. It uses 3 tubes (before: 6N9P, after class: 6080*2) were used as two stereo left and right channel amplifier. The input signal is the audio signal from the CD player or decoder, an amplified output signal used to drive headphones. The machine also has a road as a RCA signal output by the first stage, supply other amplifier as before use. MK9 uses tube amplification circuit in the electronic is relatively rare in...

Features: The All-New Little Dot MK III 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. Specifications: SEPP (Singled-ended Push Pull) OTL in Class-A Frequency response: 12...
