Sorry for the late response, I was on vacation for a week
Congratulations on the Ushers, while I have not heard them....they have an excellent reputation.
Pontus II 12th - This is a giant killer of a DAC, much like your speakers....the kind of equipment that I am drawn to. IMO it is the best DAC under $3,500, and incredibly musical. I will only upgrade when I can afford a higher end Lampizator or the Denafrips Terminator Plus 12th or the like.
I use the Non Over Sampling mode (NOS), as I find it to be more musical and slightly warmer and "magical" especially on vocals. I can see some preferring the over sampling mode, to eke out some more detail, but I find it to be too analytical and less involving. I also use the slow filter, as I find the fast filter removes some of the detail.....it could be useful in a bright overly detailed system though
Another thing about the Pontus II (and other newer DACs frankly) is the use of an I2S input. I have a BlusSound Node 130, which has the USB output turned on (which your Node 2i does not). I take the output of the Node 130 via USB to a Denafrips Iris DDC and then I2S HDMI cable to the Pontus II DAC. This also was a very noticeable bump in quality, both the better clocking and the I2S connections probably equally contributing to the SQ bump.
