MikeK, I have no USB conflicts so not worth the risk to me. I will reinstall Windows soon enough because I am on fast track insider.
Ted, as usual you have me pretty impressed. Using Windows 7! I think we are a lot alike. I Dev C#,C++,VB,Java,HTML ETC. My high end(or low end rather) audio computer is a stripped specialty audio mainboard with outboard 12V linear PSU also powering a SOTM USB card into an Intona pro into another DAC. The OS is “Daphile” based off of a stripped Linux kernel tailored for audio. If you followed me on my USB rant this is why I felt I heard no difference in the Matrix 2. I am also using a modified Aurender W20SE in that system as well.
That aside, I have given up trying to remove the “DFU” and simply have disabled it. It is to flash firmware to the DAC from the PC. I do not think PS Audio intended for it to be installed but somehow it was. I certainly did not do so myself. The PS Audio driver package simply would not install on this machine. I have no “PS Audio” folder in “C:\programs” According to Mark and TJ, this machine is just too fast for it to install. Too many clock cycles. So, I unpacked the contents of the folder and installed the .inf which in turn of course installed the .sys via the device manager. I then just used one of the many Foobar Wasapi plugins. One I particularly prefer. This machine having the “horsepower”. I am running the “SACD” plugin maxed out. Indeed, upsampling to the limit before the DSD. I doubt you agree with that? To me, with Windom now broken in with this setup is nipping on the heels of any DAC currently made at any price. I have here the MSB Select DAC II loaded with mono power bases for comparison. It is getting close! I certainly hope the TSS knocks it out of the park then! I will retire the MSB at that point.
I really cannot complain about the erroneous file. Given the sublime sound I have. I am smart enough at least not to accidently attempt to flash firmware to the DAC from the PC side. So at least it should be safe in my hands. I guess this is the end of this story. Unless someone actually knew the path of that file there is no way of finding it. Since files in DriveStore do not use the actual file name as you are aware. Thank you Ted and everyone else that attempted to help!
