Roon RAAT and "An audio file is loading slowly"

[Confused]

As a point of clarification, when using AIR the Devialet does indeed dictate the rate of data transfer, not the sending device or software.  I guess there is a clue in the name, with the "A" in AIR standing for "Asynchronous".  In the past I have tried setting a fairly high buffer in AIR and you can then remove the Ethernet cable when music is playing, and for a couple of seconds the music continues playing.  The Devialet runs down whatever is left in the buffer even when disconnected to whatever put the data there.  So clearly the Devialet is in control.

From the temple of truth:

AIR offers two different set-up options, asynchronous BitPerfect or asynchronous fixed broadband, to ensure the best possible service quality in even the most unreliable network environments. Asynchronous BitPerfect mode provides optimal audiophile-grade conditions: music is transferred from your computer or smartphone to the amplifier with zero alteration to audio samples. This mode of transfer occurs at the exact same rate as Expert Pro digital-analog conversion rather than the speed imposed by your computer. The amplifier therefore dictates computer behavior rather than the opposite, with AIR intelligence split evenly between the two devices.
Smart buffer management guarantees minimal latency and optimal capacity availability. It’s as though your music were already pre-downloaded and available from RAM memory immediately upstream from digital-analog conversion.
By dramatically clearing the pathway from audio content source to analog conversion, AIR keeps overall digital jitter to an absolute minimum. For radically superior clarity and transparency all throughout playback.
