Key Features
The HELM Audio BOLT DAC/AMP is designed to bring studio-quality sound to your phone and is capable of rendering MQA files for hi-res audio. Compatible with Android, Apple and Windows devices, you're free to enjoy uncompromised hi-res audio on any device. The HELM BOLT can stream music at over 8 times the sampling rate of CD-quality supporting sample rates of up to 384kHz, or DSD files with sampling up to 5.6 MHz, this includes music from streaming services such as Tidal, Nugs and Xiami
THX certification ensures that the BOLT can offer ultra-low harmonic, crosstalk, and crossover distortion. A physically isolated design keeps the DAC separated from the USB connector and a three oscillator design offers a superior frequency lock. Headphone impedance is set automatically and sets levels accordingly, leaving you to enjoy your favourite tracks in hi-res brilliance, with multi-dimensional detailing.
