@lobinero - If you want to get the very best out of the Node2i I can recommend getting some quality cables - i.e. Power cables + Interconnect - like those from Zavfino
The Fusion - Solid Pure Silver & OCC Copper - ZavfinoUSA
Pick a power cable with UP-OCC copper conductors - or the silver cables are even better.
The Node 2i uses a 2 pin plug qand Zavfino does not yet have a 2 pin cable - but you can use an adapter
You will notice improved dynamics, clarity, details and image
It might seem a little strange putting such high priced cables on such an affordable Streamer, but it pays huge dividends in sound quality.
I consider cables as important as my components and using high quality cables throughout has had a huge impact on the performance on all of the components.
Once the cables are addressed then you can upgrade other components with the knowledge that the cables are allowing them to perform to their very best ability.
.I have the Node 2i and it amazed me as to how good it was - once I treated it to some good cables
