Kaiboer PureOS V1.5.38 Firmware Update All three upsampling solutions are ready!
To all dedicated audiophiles, Kaiboer is rolling out the major V1.5.38 firmware for the full PureOS streamer lineup. This update introduces the brand-new High-Res Upsampling Engine with native real-time DSD remodulation, completing our trio of upsampling methods for different listening needs.
✅ Couvora Generative Upsampling: Offline pre-render your music files. Lower playback load and convenient for A/B comparison.
✅ HQPlayer NAA Officially Licensed Upsampling: Offload heavy calculation to your PC, abundant filter choices for hardcore audiophiles.
✅ New Onboard High-Res Upsampling Engine: Real-time audio processing, no computer required.
It supports Bypass mode, PCM high-precision upsampling and real-time DSD remodulation to DSD128. Two built-in filters: Kaiser and Blackman-Nuttall, which reduce digital harshness and deliver warm, analogue-style sound to your beloved music collection.
Every PureOS model comes with an M.2 NVMe SSD slot supporting up to 8TB storage for your CD rips and high-resolution music library. With onboard upsampling, real-time calculation works instantly during playback with no pre-conversion needed.
💡A friendly reminder: Upsampling is algorithmic audio processing. Final sound is affected by your entire HiFi chain. We recommend A/B testing with your favourite reference tracks.
The firmware begins grey rollout today and will be fully available by October 10. Keep exploring new HiFi possibilities with continuous PureOS upgrades.
