we are a roon dealer their hardware is decent your dealer should try a better server
we have tested the node and the nucleus vs our 432EVo servers and the high end and aeon models sounded way more like an analog source however they are way more expensive devicesat $5500 and $7500 rerspectively
for this reason we decided to import threm into the us so yes trhe ource feeding the dac is important
