Orchard Audio’s New PecanPi®+ DAC and Streamer Feature AKM’s Latest Flagship Chips

Orchard Audio introduces the PecanPi+ DAC and PecanPi+ Streamer, further expanding the highly reviewed line of PecanPi® products. The PecanPi+ DAC leverages Asahi Kasei Microdevices’ (AKM) latest flagship AK4499EXEQ digital-to-analog converter (DAC), and AK9141EQ ΔΣ modulator chips. The 4499 utilizes the latest multi-bit switched resistor DAC method, employing VELVETSOUND™ technology.

AKM’s design separates the digital processing and the digital-to-analog conversion into separate devices, minimizing the effects of digital noise within the analog output and resulting in a noticeable improvement in both sound quality and signal to noise ratio. The PecanPi+ design fully explores the benefits of the latest technological advancement in audio reproduction, providing pure, unaltered audio that wholly reproduces the source material. The AKM chips are coupled with extremely low noise power supplies, an ultra-low jitter clock, and the latest high-performance audio operational amplifiers from Burr-Brown (Texas Instruments). This enables the PecanPi+ DAC to achieve staggering performance.

The PecanPi+ Streamer is a plug-and-play high-resolution music streamer. Control music wirelessly using your phone, tablet, or computer. The device can also be connected to any digital transport utilizing S/PDIF. The PecanPi+ DAC is ideal for do-it-yourself (DIY) enthusiasts.

Preorder pricing is available thought the end of March.

Here are some test results comparing the PecanPi vs the PecanPi+. Note that I had to borrow and APX555 because the 525 that I have is not capable of measuring the performance of the new PecanPi+ DAC. I think that alone says a lot.
