Descriptif de Expanse
In short, Expanse is a feature for the Bartók Headphone DAC Amplifier that utilises cross feed to shift the perceived sound source with headphones from inside the head to in front of the listener. We deemed this a worthy feature for the Bartók as there is a growing imbalance between how music is monitored during recording, mixing and mastering – on loudspeakers – and an ever growing number of users listening to music on headphones at the playback stage.
We didn’t feel that any of the existing cross feed technologies were worthy of inclusion in our products. For example, the majority of existing cross feed technologies rely on the addition of artificial reverb to compensate for reverb levels appearing reduced when listening on headphones. While such technologies will go a way to shifting the sound source outside of the listeners head, it does so at the expense of the sense of space within the recording.
Instead of adding in artificial reverb which was not present during the production of a track to combat this issue, Expanse aims to preserve the reverb of the original recording while applying cross feed. This brings the soundstage more in line with what the engineers would have been hearing during production, without doing so at the expense of the spatial information of the recording.
