With the Sony Walkman NWZ-A17 are sound settings like DSEE-HX nullified when using Apt X Bluetooth to connect to an amplifier. Are they also lost using a headphone amplifier via USB? What about a headphone amp that uses the headphone jack it seems they would stay in tact, but would noise be introduced?
Welcome and thank you for considering SONY Community!
The DSEE HX feature of this Walkman will not be nullified using AptX bluetooth connection and they will stay in tact even when using amplifier via headphones jack. This specific feature will not be available on some functions like Karaoke function and Dance Mode.
