WIIM PRO+
Audio Streamer Bit-Perfect DAC AK4493SEQ
WiFi AirPlay 2 DLNA Chromecast Multiroom Bluetooth 5.0 24bit 192kHz
Spotify Connect & Tidal Connect
With the WiiM Pro+ you can stream your music directly from the Spotify Connect and Tidal Connect streaming services, without using the WiiM Home application.
Simple system
Direct to your AMP or powered speaker without external DAC.
Audio quality is comparable with WiiM Pro connected to the external DAC.(up to $300 price).
Compatibility
Resolve compatibility issues with some (low-end) DACs that don’t handle the clock, variable sample rate/bit depth properly, or don’t support up to 24-bit/192kHz digital input.
Better audio quality for analog input
The better audio quality for analog input sources.
Cost Effective
Save the external DAC and cable costs.
Better ADC for Line Input
It uses TI Burr-Brown Audio PCM1861 ADC, achieving up to 192kHz/32-bit digital output, 110 dB SNR. Thus, it provides high-fidelity analog to digital conversion for input from a record player, MP3 player, or TV.
Ultra-low Noise Clock, Power, and Circuit Design
It uses an ultra-low noise clock, power supply, and careful PCB layout to achieve less than –110dB THD+N performance for analog audio output.
AKM DAC and TI OP AMP for Better Line-Out Audio Quality
It features a new generation AKM 4493SEQ premium DAC that is able to achieve a leading level of low distortion and wide dynamic range thanks to AKM’s Velvet Sound Technology. It supports up to 768 kHz PCM, and DSD512, with PCM/DSD automatic switching ideal for the latest high-resolution audio source. Achieve 120 dB (A-wt) SNR, THD+N of 0.00032% (-110 dB) from 44.1k to 192k.
FR Curve
SNR
Offering more streaming services and audio content that incorporate MP3 quality, lossless audio, or immersive sound technologies for their listeners. WiiM devices provide the capability to play Hi-Res lossless audio contents from Spotify, Amazon Music, TIDAL, Deezer, Qobuz and more. It supports up to 192kHz, 24-bit audio output which is the same as artist’s recording in the studio . The integrated TI stereo DAC provides the high quality analog audio output with the 106-dB SNR, dynamic range and -92dB THD+N performance, outstanding in all audio categories.

Auto calibration of audio delay
The connected receiver or speaker may have different audio path latency due to different hardware, software and DSP processing. To maintain the synchronization of each system, it’s desirable to measure the audio path delay automatically. By leveraging the on-device microphone and proprietary algorithm, the entire audio path latency is measured automatically when it’s connected with the receiver or speaker. The latency value will be used to maintain the perfect audio synchronization in wireless multi-room playback with HomePod, Echo, Google Home or other WiiM devices.
