Pro Plus

The WiiM Pro Plus was a significant upgrade in terms of audio quality for analogue audio input and output, total system cost, and system setup. These enhancements aimed to provide users with a more powerful, high-fidelity, and hassle-free music streaming experience compared to the previous model, the WiiM Pro.

What are the differences between the WiiM Pro and the WiiM Pro Plus?

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 analogue 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 analogue 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.

Line-out performance

SNR： 120dB (A-wt)
THD+N(1 kHz)： 0.00032% (-110 dB) for 44.1k to 192k
FR curve： +/-0.05dB

Unrivaled Sound Quality up to 192 kHz/24-bit

Diverging from the norm of resampling to set sample rate and bit depth, WiiM Pro stands out by delivering unaltered audio up to 192kHz, 24-bit quality. That's the same as an artist's recording in the studio. The advanced TI PCM5121 DAC produces a remarkable 106 dB SNR and an impressive -92dB THD+N performance.

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 analogue audio output with the 106-dB SNR, dynamic range and -92dB THD+N performance, outstanding in all audio categories.

Easy to Setup

The WiiM Pro Plus will automatically pop up in your WiiM Home app. The in-app guide will thereafter aid you in the rest of the setup, and you will be able to start streaming music in less than 2 minutes. The Pro Plus is designed to be connected straight to the analogue inputs of your amplifier or active speaker, but for other applications there's still optical or coaxial outputs available.
