AFAIK, the sole purpose of deemphasis was to reduce tape noise in analog recordings - almost never used today, since most of recordings are digital. CD players have deemphasis built in and engage it automatically (CD contains deemphasis bit).
De-emphasis in DAC
Hello, I have the Burson Audio Swing DAC, it has the option to use de-emphasis, I would like to know if this option turned on, listening to FLAC, WAV, .dsf and .dff (DSD) files, makes the music lose information and details.
According to Burson Audio, this option is used when the source material is recorded on master tape, what it does is cut high frequencies and noise from the tape.
I have the Totem Acoustic Rainmaker loudspeakers, it sounds shrill and bright with many records, but when I use de-emphasis on the DAC those high frequencies are controlled and the shrill and bright sound is quite eliminated, but I don't know if the music loses information this way.
