    Anyone got a download link to this new official release ? Cheers, KJ

    Ask directly to Kingwa. He will send it fastly.

    1am here in our region, and heading into a Sunday, so I would not like to bother him. But I got it via email from a kind soul here already, will try tomorrow

    I tried the latest update on my r8he coming from asy3. Soundstage appears big but there is a treble rolloff and it does not sound as anayltical as asy3. In short new firmware is smoother in high frequencies and there is more of an enveloping sound than before. Male voices are surely better in new firmware but i am not sure overall i like it more or not. I surely miss the treble.

    Do you know if optical on input 4 would work with DSDCLK on the M7S? I finally received the USB Blaster you recommended and need to choose which firmware to install. I was going to use R7V3 but all the hubbub about DSDCLK has me interested in that.

    I don't think it would.. I woukd recommend tda_asy3. It is awesome IMO and is available for your dac AFAIK.

    @Tango Sierra i have no way to test IN 4 Optical but my understanding is that these recent parallel firmware files support optical.

    And DSDCLK firmware sounds great on the M7S. OS and NOS are super. If you have a good I2S source I recommend it. All inputs sound good as well.

    What is the Altera filename for the “official” R7 asynchronous parallel firmware? Is it just the latest and greatest firmware? Is there new functionality? I may have it but want to verify if my file is the one mentioned today as official. Thank you!

    Is there no longer (currently) a accurate and smooth version? Has it just been merged into a single 'dsdclk' version?

    The filename is "R7tda_Asy_P_rmdsd_dop.jic"

    Interesting....
     
  12. DACLadder
    Kingwa must have added or expanded DoP capability.
     
  13. FredA
    Yes, it's DoP through spdif support.

    Yah the VH audio are having them on sale. But I am confused as to where to put them. VH audio stated they are mainly for the analogue stage, at least the cheapest small one they are selling. So where exactly should one put them? And one is needed on each analogue channel ?

    Thanks!

    Here's the newest R7 firmware file (R7tda_Asy_P_rmdsd_dop.jic). Compare sound quality as I find I like DSDCLK better with PCM I2s or USB OS8. YMMV, of course, as the differences are small. What do you think?

    All files in this folder are intended for the older DACs (no 10M ext. clocking, Optical IN4)).
