Audiobyte products are designed (as well as owned) by the same designer and owner of Rockna. These products feature most of the performance at a more affordable price.
By doing away with fancy (but still high quality) case work.....
The VOX is a unique D/A converter with a headphone amplifier and external power supply. Its entire architecture is using Audiobyte proprietary technologies. Every feature was developed through extensive research to provide
The architecture of the VOX is pure 1 bit. All incoming sample rates are converted inside to a sample rate equivalent to DSD256/512 (firmware dependent), after which analog conversion is done using current segment technology.
A unique feature of the Hydra.VOX is the seamless integration between analog and digital filters in orders to preserve accurate phase of the audio signal. It is well-known that any analog low-pass filter will add a phase distortion input-to-output altering sound quality.
To avoid this from happening, the digital filters inside FPGA are programmed to exhibit a “mirrored” phase response, thus cancelling the phase error from the analog domain. The result is a perfect phase response over the audio band.
