The Benchmark DAC3 delivers a clear, open, and uncluttered playback across the entire frequency range.
Instrumental overtones are rendered with exceptional precision and realism. Vocals are reproduced with outstanding accuracy and natural tones. Transients are fast and precise. Bass is deep and well controlled.
The ultra-linear phase response of the DAC3, allows it to create a precise three-dimensional rendering of the recorded space. This space is open and uncluttered because noise and distortion are held below the 0-dB SPL threshold of hearing at all playback levels.
This experience is not limited to the line-level outputs. The DAC3 HGC includes Benchmark's HPA2 0-Ohm Headphone Amplifier which easily drives difficult headphone loads.
