I have the Node 2i and would be very happy with the internal DAC if it was my only option but I am currently running it through an external DAC to my preamp. I do find the DAC in the Node 2i to get better at higher volumes.
As others have stated go with the SPDIF Coax cable from the Node to your preamp to test the DAC in the Hint. You won’t get the higher res transfer from the Node using an optical cable.
You should be able to also connect the Node from the analog outputs in the Node to the Hint and switch inputs back and forth to compare the DAC's one after the other.
