    Windows 10 Worth It?

    They finally got rid of Mosaic that was at least underlying tech for IE!?
  2. What is wrong with it? I haven't seen anything to complain about on mine...

    If it works fine for 30 minutes after startup, then it is likely demo mode. After some playback time it goes silent too although you can still restart the playback.

    For troubleshooting it is good to simplify the setup as much as possible. So if you are using NAA, try removing it from the picture and connecting DAC straight to HQPlayer computer. Same also for source, try playing back files only using HQPlayer, from local storage and without Roon or such. If this works, you can step by step put things back and see when it stops working. Otherwise there are too many variables in the picture and it is hard to figure out where the problem could be because it could be in so many places.

    Are you always playing to the same NAA? Sounds like the problem is there and the ASIO driver is having some trouble... That's also why changing HQPlayer machine between Windows/Linux doesn't change anything because NAA's are always handled same way.

    No, but the service needs to be restarted to continue...

    On Ubuntu for example that MediaRenderer2.xml file is found in package "rygel", which will pull in tons of unnecessary stuff too, although only that single XML file ends up being used from it. But you don't need to run the "rygel" process at all...
  8. One way I use to improve linearity of those R2R's and work around setting time issues is to figure out the linear range at wanted sample rate and then set output word length to that one and employ noise shaping to increase dynamic range in audio band. This is why I added possibility to set output resolution in one bit steps in HQPlayer, for example to 17- or 19-bit.
  9. I have a Metrum Musette and that's where the results are from. Performs a lot better when running at 352.8/384k rate. Holo Spring has two DACs in one box, R2R ladder - which performs notably better too at 352.8/384k. And DSD multi-element array that is similar to my DSC1 design, which performs best at 22.5792 MHz. I also have Holo Cyan DSD DAC, which is DSD-oly DAC and a bit like Spring, but without the R2R part (but Cyan has sweet spot more around 11.3 MHz). Denafrips is another that is similar to Spring. BB PCM1704 which is a ladder DAC can run at 705.6/768k rate with good performance. It really depends on a particular design how much the R2R rate can be increased before settling time ruins the performance. 16-bit part can be certainly run at higher rates than 24-bit part, because for LSBs to have effect, the DAC needs to settle to +-½LSB within fraction of the sample time for the precision to be useful. It is hard to say where the limit is without testing.

    There's only one ASRC and it is now called ASRC. All others are synchronous. Processing itself is asynchronous and completely independent of DAC's clock, but synchronous to the sampling rate (mathematically, but not in relation to time). There are no compromises with synchronous converters as such. ASRCs have compromises because they need to be able to adjust the resampling ratio constantly on the fly. But the way the one ASRC is used in HQPlayer, it is not adjusting ratio on the fly.

    You just install new over old one, you don't need to remove old, the packaging system takes care of that when installing new version.

    All DAC chips except "low end" ones rely on external master clock... Same for ESS, TI/BB, Cirrus/Wolfson, etc.

    What do you mean by slave mode?
  14. To me it looks like two 4497's on one chip. Not sure how different it is from driving two 4497's in dual-differential mono mode (like TEAC UD-505). But good to see some proper competition between ESS and AKM! For small manufacturers, obtaining ESS chips has also been PITA, while AKM has been moving to opposite direction for more general availability. For a long time AKM was almost solely used only by pro-audio recording/production equipment. Great to see that it is now becoming more and more to hifi playback gear too!
  15. The original wall-wart for CuBox-i4Pro is 5V 3A. So that is a good starting point. Usually the device takes most power when booting up. Sometimes if the PSU cannot give enough peak current, device goes into reboot loop. I have so much 5V DC barrel power connector hardware that nowadays I just have 5V 6A power brick at hand all the time.
