HELM Audio Bolt DAC/AMP

USB-C Portable High-End DAC/Headphone Amplifier with MQA Playback. Mobile Studio Sound for Android, iOS and PC. USB-C to 3.5mm Audio, THX Certified

by HELM
What We like

THX CERTIFIED AUDIO OUTPUT: Exclusively designed for ultra-low harmonic, crosstalk & crossover distortion. Unlike other mobile MQA-DAC designs, the HELM BOLT physically isolates the DAC from the USB connector for improved EMI isolation, and uses a three oscillator design for superior frequency lock with dramatic improvements over single oscillator DAC designs.

Product Features

  • The difference between B4 and B4-X: B4-X is a dual-mono balanced version. Its left and right channel are amplified by independent components, and power supply, tubes, and op amp are all independent and symmetric. So the degree of sound separation is higher than B4.
  • With built-in battery protection circuit: battery lets your listening feast without time limitation. It can't be turned on during charging and will power off automatically after fully charged, and charger LED will turn to green.
  • B4-X adopts 2 groups of independent power supply(+12V and -12V) for 2 op amps, less mutual effects and can drive 300 headphones. The circuit adopts dual op amp parallel output, with higher output power. B4-X has 3.5mm and 2.5mm 2 kinds of output interface, suitable for most of balanced and standard headphones.
  • Mini size and unique design: built-in tube makes you have a tube amplifier which can be held by one hand, convenient to carry and can enjoy HiFi music everywhere. Full, delicate and soft sound: warmer than transistors, independent op amp and power supply inhance the SNR and degree of separation, less interplay and higher sound quality.
