It’s possible to set some parameters related to the
HIFACE Evo 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. 5.
It is now possible to listen to music by simply selecting the USB input on the
HIFACE Evo
Two
and using iTunes. Please note that even when the chosen playlist includes tracks
with different sampling frequencies, the
HIFACE Evo 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
HIFACE Evo Two
as output device. As an example, Fig. 6
shows the configuration window of Audirvana. Please note it is necessary to choose the
HIFACE Evo 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
HIFACE Evo
Two.
Therefore, we suggest using them whenever possible.
8.1.1. DSD files playback with Mac
The
HIFACE Evo Two
is able to transfer music files recorded with the DSD format. A player
able to send DSD data to the
HIFACE Evo 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. 7.
