Product Description

Nobsound Little Dot MK2 MKII SEPP 6J12 6N62 Vacuum Tube Headphone Audio Amp Amplifier Pre-Amp Upgraded Nobsound

This is little Dot new model of MK II,and it Has the following improvements:

  • Using the SEPP single-ended push-pull circuit, the output dynamic range and sound quality better than using cathode output;
  • The selected materials have been optimized: ALPS-16 potentiometer, NICHICON filter capacitor, WIMA / ERO coupling capacitance, etc;
  • The new circuit design makes the machine to reduce the heat capacity;
  • The shell is made of a secondary oxidation process, better surface finish and texture.
  • Modify the preamp output circuit, reducing the output impedance, with a load capacity stronger.

Top Features

  • This is little Dot new model of MK II (original listing: B00A2QMAI2). It uses the SEPP single-ended push-pull circuit, the output dynamic range and sound quality better than using cathode output.
  • The selected materials have been optimized: ALPS-16 potentiometer, NICHICON filter capacitor, WIMA / ERO coupling capacitance, etc; The selected materials have been optimized: ALPS-16 potentiometer, NICHICON filter capacitor, WIMA / ERO coupling capacitance, etc
  • An SEPP (single-ended push pull) OTL circuit operating in Class-A, the Little Dot MK II greatly increases sound quality, dynamic range, output impedance, and harmonic distortion over the celebrated Little Dot II++.
  • The Little Dot MK II now also provides gain control of 3, 5, and 10 via internal DIP switches for fine-tuning so you can maximize synergy with almost any headphone you have, whether it be 32 ohms or 600!
  • The Little Dot MK II also gains the driver tube-rolling options from the rest of the MK-series with the ability to roll 6JI, WE403A/B, GE5654, M8100, CV4010, EF95, etc at its factory jumper setting, and with jumper pins shorted, EF92, CV131, and all equivalents and drop-in replacements!
