@FredA ??? It says that it applies to USB and HDMI-IIS both...? We should both be happy (I run USB; the very good USB output from the SOtM sms-200 ultra neo isn’t improved by neither my ifi iUSB3.0 nano nor my Singxer SU-1).

@FredA If you check the new R28 (2020) description on new features, under point 2 you have The FPGA process data upgrade to parallel mode. The IIS data is series transmit mode, every data must need one clock cycle to process or transmit, one frame data ( Include L and R data) must need...

@FredA Could depend very much on the rest of your gear, as well as your personal preferences. What works for me may not necessarily work for you :boy:

Is it only me, or did anyone else notice that the full impact of the software upgrade took a few hours to reach? My theory is, that since this is FPGA and not CPU, with FPGA having a set of fixed circuits interconnected by the Quartus programming, it simply requires some burn-in like any other...

Turdski I'm not sure what the previous firmware version was. I received my R-28 in mid August this year, so I guess it was whatever was the newest back then. Note of potential interest: I ran the Quartus FPGA software in a virtual machine of Windows 7 Professional in VMWare Fusion 10.1.1 on a...

DACLadder Thank you for the advice. I had indeed no connection to the Cyclone. What actually ended up working is switching places of the connectors... the 10-pole connector end I used in the DAC, I put in the USB Blaster instead and vice versa. Not sure why that would matter, but hey, it...

I tried the Parallel_DOP update on my R-28 (2019). It failed. Any ideas why? The program seemed to find the FPGA alright - it looks just like in Kingwa's installation instruction, only that it failed just a couple of seconds after pushing the Start button (text "Failed" in the Progress cell)...
