A Massive Update

Hear Paul’s thoughts on what makes this Mountain Top update our best in 50 years. The Mount Massive update includes:

  • Lowered ultrasonic noise by 30dB
  • Moved what ultrasonic noise remains out from 30kHz to beyond 100kHz
  • Lowered audible noise by 10dB
  • Added a new Digital Lens FPGA buffer
  • Improved sound quality dramatically
PS Audio are very proud to announce the new Mountain Top update for our DirectStream DAC MK2 – Mount Massive. This revolutionary free upgrade brings a new life into an already impressive Digital to Analog converter. As Paul puts it, “This is the single biggest upgrade I have ever heard in the 50 years that I have done this. It’s huge… It’s really, really big” You can download the Mount Massive update for free from our downloads page or purchase a USB pre-loaded with Mount Massive.
Since its groundbreaking introduction 8 years ago, the PerfectWave DirectStream has stood alone as one of the most remarkable DACs ever built. PS Audio 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 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 at 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.
