Streaming Presto Music purchases through WIIM Mini degrades the Hi Res.

[JFL]

Hi,

Listening to music purchases from Presto Music through WIIM Mini is not the right Hi Res bitrates.
For example,"Last decade" from Benjamin Lackner is Hi-RES 88.2 kHz, 24 bit but when I use the WIIM Mini app to listen to it it downgrades to CD quality(16-bit144,1khz.
So what is going on?
Thx,
Jean-François

It would appear Presto are using Airplay which is restricted to 16/44.1 by Apple, but at least it appears to be lossless CD quality rather than the lossy 256kbps AAC Apple Music experiences.
