It's possible to set some parameters related to the EVO PHONODAC TWO operation
(specifically, the sampling frequency at which the Mac will send audio samples to the
DAC) by the MIDI Audio window, as shown in Fig. 10.
It is now possible to listen to music by simply selecting the USB input on the EVO
PHONODAC TWO and using iTunes. Please note that even when the chosen playlist
includes tracks with different sampling frequencies, the EVO PHONODAC TWO will always
display one sampling frequency that is the one selected in the MIDI Audio panel (Fig. 15).
This implies a real-time resampling feature by the Mac's operating system which is seldom
welcome by the user. In this case, another player should be used which is able to
automatically change the above setting, like Amarra, PureMusic and Audirvana. Unlike
iTunes, other players need to be properly configured to use the EVO PHONODAC TWO as
output device. As an example, Fig. 11 shows the configuration window of Audirvana.
Please note it is necessary to choose the EVO PHONODAC TWO as Active Audio Device.

Also please note that amongst the available options are those related to Direct Mode and
exclusive access to the resource ("Exclusive Access Mode"). They are peripheral access
modes which provide a higher listening quality and which are supported by the EVO
PHONODAC TWO. Therefore, we suggest using them whenever possible.

10.1.1. DSD files playback with Mac

The EVO PHONODAC TWO is able to transfer music files recorded with the DSD format. A
player able to send DSD data to the EVO PHONODAC TWO in a standard format handled by
the DAC must be used. As an example, the configuration of Audirvana necessary for DSD
files playback is shown in Fig. 12.
