Hi
I think the Bluesound products default to the highest resolutions for each given platform. I know in the portable version of Qobuz you can select the samp,e rate to minimize use of data with cell or wifi connection. The Vault and Node can not do this.
If you only play 44.1 tracks your DAC should be able to cope and lock onto the signal
My Aurender has a filter in the search function where you can have it only display lower or higher resolution content. Qobuz sample rate is also selectable .
