Problem with BL50 at 24 bits/192 kHz bitrate on coaxial input

[YannChris]

Hello Beoworlders,

The Beolab 50 technical guide states that the Toslink optical input is limited to 24 bits/96 kHz and that the SP/DIF Coaxial one supports 24 bits / 192 kHz signal.

My BL50s are connected to a Wiim Ultra streamer with the 5 meters SP/DIF coaxial cable previously used for BL5s.

They work perfectly at 96 kHz but there is no sound at 192 kHz.

I tried several cables and several streamers with the same result, which make me think that the culprits are the speakers.

BL50s owners, is it the same for you?

Kind regards,

Yann.

My guess is that the problem lies in the WiiM digital clock (quality of the clock)

Quick back-ground reading on the Wiim suggests to use the Optical instead of its own USB (may be a tell).

The likely Wiim worked Ok with the BL5 because I think the BL5 was limited to 88kz on coax input

 

Three possible workarounds.

1. Buy a high accuracy “Digital Clock” this will clean up the signal from the Wiim. Most likely to work with the BL50s. will give the best quality sound
2. Throttle the Wiim Digital output to 96kh or less. You may notice more digital “noise”
3. Feed the RCA Analogue outputs from the Wiim to the BL50. I feed my Auralic DAC into my BL90s via XLR. I prefer the sound but it may be dependant on the quality of the DAC in the Wiim.
