DirectStream is one of the most remarkable DACS ever built. Hand written, discrete, perfection based conversion that uncovers all the missing information hiding in your digital audio media for all these years. CD's, downloads, high-resolution PCM or DSD based media are expertly upsampled in the DirectStream to ten times DSD rate and output as pure analog directly into your amplifier or preamplifier.
