I have a Pontus II in my secondary system which I did the recent FPGA firmware update for and I found the sound quality changes to be sweeping improvements. Very happy with it, and hearing similar results in quality to what most here have been saying. I'm using the NOS mode now instead of the OS mode because it sounds good. Has it been confirmed by Vinshine Audio that this DAC now features a true non-oversampling mode with the recent firmware update?
