@mdalton Interesting to hear that the HiFi News & RR lab reports show that the Pro-ject streamer has very low levels of jitter and other noise.
@aldnorab I've only tried one Wi-Fi extender, but the improvement it made over using the streamer's built-in Wi-Fi was immediately obvious.
One way to improve your current digital source is my removing noise from your system. I got an Audioquest Niagara 1200 power conditioner. It's been useful in unlocking more clarity and resolution.
