- More presence to voices and instruments which sound more forward and distinct in presentation
- Richer tonality
- Less grain to the sound
- Better resolution due to a lower noise floor (This is audible when comparing a cleaner signal to one that is less clean)
- Easier to follow bass lines
- Pace seems faster due to more clarity and better definition to the leading edge of notes.
When experimenting with my Pro-ject Stream Box streamer, these changes made a clearly noticeable difference to my ears at least. (NOTE: Your perceptions may likely vary as with anything audio):
- Turning off the WiFi and HDMI outputs and using an Ethernet cable connected to a WiFi access point created with a TP-Link RE230 WiFi extender - This cheap fix made the biggest improvement of everything I tried.
- Going from an AmazonBasics Cat 6 cable to a Supra Cat 8 cable - This provided about 50% of the improvement as #1
- Adding a Audioquest Jitterbug on the output of the Pro-ject Streamer - Makes the sound more transparent. Adds more air and presence to music
