The PecanPi®+ DAC is based on Asahi Kasei Microdevices’ (AKM) latest AK4499EXEQ chip. This device uses the latest multi-bit switched resistor digital-to-analog (DAC) method, employing VELVETSOUND™ technology.

PecanPi+ DAC:

Experience audio refinement like never before with the PecanPi+ DAC. Designed to elevate your sound quality, this DAC (Digital-to-Analog Converter) is a testament to precision engineering. Unleash the full potential of your music, as every note is transformed into a vivid, immersive sonic journey. The PecanPi®+ DAC redefines your audio experience, ensuring clarity, depth, and richness that resonate with true-to-life resonance. Whether you’re an audiophile seeking the purest sound or a professional fine-tuning your studio setup, this Headphone Amp with DAC stands as a paragon of uncompromising quality and performance.

All of the digital processing is done by the AK4191 and the digital-to-analog (D/A) conversion happens in the AK4499. By splitting these two functions into separate devices AKM has minimized the effects of digital noise within the analog output, resulting in a perceived improvement of the ratio of signal to noise. Turn your single-board computer (SBC) into the ultimate music player. No other Rpi DAC offers this level of dynamic range, dual DAC chips, and an amazing built-in headphone amp. It can also work completely on its own using the S/PDIF input.

AKM’s AK4191EQ ΔΣ Modulator is employed alongside the AK4499EXEQ.
