The Node 2i has a perfectly serviceable DAC, but “good enough” isn’t usually the goal. I noticed an improvement running into an Oppo BDP-105, but the Oppo is limited to 96kHz input through S/PIDF. I’m not saying the sample rate makes a huge difference but I wanted to at least have the option of running the Hi Res material that is out there. Contrary to what some people keep insisting, the Node 2i can output 24/192 over both coax and optical. So while the Oppo opened up all the buzzwords (air, articulation, detail, bass, etc.) over the Node’s internal DAC, it was close enough that I doubt I could identify which I was listening to cold, but it was obvious with an A/B comparison. So I did what most of us would do and decided to throw more money at it. Using a Chord Qutest now and my DAC is at the bottom of the upgrade list. Everything else will need marked improvement before the Qutest becomes the weak link in my system.
An external DAC is not necessary with the Node 2i, but it can definitely be worth it.
