DirectStream is one of the most remarkable DACS ever built as all the major reviewers agree. Hand-written, discrete, perfection-based conversion that uncovers all the missing information hiding in your digital audio media. CDs, streaming audio, high-resolution PCM or DSD-based media are expertly upsampled in the DirectStream to twenty times DSD rate and output as pure analog directly into your amplifier or preamplifier. There has never been a better-sounding DAC at anywhere close to the price of DirectStream. It is the first choice of thousands of critical listeners worldwide, and with its ability to accept our free Operating System upgrades, will never become obsolete.
