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 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, 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.
Super easy setup
WiiM Pro will pop up automatically in the WiiM Home app.Follow the in-app guide and start streaming music in less than 2 minutes.
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.
Multiroom and stereo pairing
Playing music in your whole house is achieved with the perfect audio synchronization and seamless device control via the companion App . With careful hardware, algorithm and software optimization, we can achieve less than 150uS (0.00015s) synchronization accuracy among speakers as long as the speakers are in the same wireless network. Thus, your speaker system can be located wherever your Wi-Fi network covers.
Gapless Playback
Precise gapless playback is important to your listening experience. With precise gapless playback, the playback timing is guaranteed to be identical to the source. It's not allowed to introduce gaps or overlaps (crossfading) between successive tracks. The gap will be very noticeable in " continous " music such as live concert recording, some classical music etc.Various software, firmware and hardware components may add up to a substantial delay associated with starting playback of track. Our player uses two decoders to remove the extra samples at the beginning and end of each file, and combine them. It works for all the supported music services and music in your phone or local network.
