You are using the Naim UnitiServe 2 TB as a source into the Aesthetix DAC. I guarantee way, way better results if you upgrade to a UnitiServe SSD and then use a streamer in front of your Aesthetix DAC. I had your set up and now have an SSD/UnitiQute 2B going into an Aesthetix DAC. I use a Sonology drive and by the way the Eclipse upgrade on the DAC is unreal.
