Guys, thank you all very much! You gave me a lot of good and practical recommendations. My view of Node 2i is that it is a very versatile and capable streamer. I'll use it alone and will change power cord, this made a difference. As for external DAC for streamer only, budget-wise I would choose to go to a next level integrated streamer. When the time comes.
Stay safe and happy listening!
