DirectStream DAC MK2
The PS Audio PerfectWave™ DirectStream Digital to Analog Converter (DAC) MK2 is a state-of-
the-art DAC that replaces its predecessor, the PerfectWave DirectStream DAC.
Since its groundbreaking introduction 8 years ago, the PerfectWave DirectStream DAC has
stood alone as one of the most remarkable DACs ever built. We are excited to share with the
world the next generation of this technological wonder, the PerfectWave DirectStream DAC
MK2.
Unlike the vast majority of high-end DACs based on off-the-shelf IC technology, DirectStream
MK2 is handwritten, discrete, galvanically isolated, 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 all expertly upsampled in
the DirectStream MK2 to twenty times DSD rate and output as pure analog directly into your
amplifier or preamplifier.
There has never been a better sounding DAC anywhere close to the price of DirectStream MK2.
The ground breaking DirectStream DAC was the first choice of thousands of critical listeners
worldwide, and now, with the introduction of the MK2, that legacy will continue.
DirectStream MK2 features a unique architecture inside. From its galvanically isolated digital
inputs to its galvanically isolated output stage, DirectStream MK2 has been hand written and
hand designed by Ted Smith.
DirectStream MK2 has two FPGAs (Field Programmable Gate Array) as the core processors and
no off-the-shelf DAC chips are used in the design.
Each input on the DirectStream MK2 is galvanically isolated, which means there are no physical
