    Certainly those group 2 apps bypass, but the devices that can be bypassed correctly are limited.
    I installed Neutron on SPK, but unfortunately it does not bypass.
     
  2. Fafner
    Do allowed Open App installable apps bypass? It would suck to subscribe to Qobuz high res to end up getting everything downsampled to 16/48. At that point; it would be better to stick to some CD quality subscription.
    Perhaps @JasonNYC can clarify on this point?

    If Qobuz App is used with SPK alone, high resolution formats such as 192/24 will be down-converted by Android SRC.
    Therefore, it is not very wise to streaming high-res source with Qobuz App. I recommend limiting to 16bit/44.1kHz in setting.
    However, this shall not apply in the case when connecting to an external USB-DAC.

    Yes, it bypasses the Android SRC. This was discussed in detail in this thread when OpenApp was added at the end of 2018.

    Thx for the quick reply. Good to know, makes sense.

    Not so. I am listening to Verdi Macbeth at 192khz on the AK SP1000 no problem. You need to have the streaming settings on Qobuz' set to the highest.

    A video of the sp1000 amp with some impression on the Kann Cube and what others are saying about the sp2000 between the SS verses CU. Also an unboxing of the tripowen C8 cable.

    I verified the high resolution playback of the Qobuz App by connecting the optical digital output to an external DAC.

    When playing 192kHz/24bit track with Qobuz App, the external DAC will display 192kHz/16bit.
    When playing 96kHz/24bit with Qobuz App, the external DAC will display 96kHz/16bit.
    (The streaming setting of Qobuz App is set to a maximum of 24bit/192kHz)

    When using DLNA control apps such as BubbleUPnP and streaming the same track from Qobuz with the AK Connect renderer, the external DAC will display 192kHz/24bit and 96kHz/24bit.

    These results are considered to represent the same state as when playback with Qobuz App on SPK alone.
    Sampling rate is up to 192kHz, but bit depth is all down-converted to 16bit.
    Therefore, when playback with Qobuz App, bit depth is considered to be down-converted. It's not bit perfect.
    It is up to you how you see this result.

    I choose a method that can playback in 24bit.:laughing:

    Of course I set the streaming setting to 24bit/192kHz.:wink:
    I'm sorry, as you said, the sampling rate is up to 192kHz.
    However, bit depth is down-converted to 16bit.

    Have quick question.

    By installing neutron.apk, how do we verify with the account that we purchased?

    I wonder if we can get a comment from Qobuz'?
     
  13. Fafner
    Given the particularity of A&K's implementation, that's something which @JasonNYC could have a better answer to.
    My DAC is just displaying sampling rate and not bit depth when being fed with an optical digital signal, thus can't comment.

    This is from A&K FB page. Wonder what this V-Link thing is.

    In settings, do you have the S/PDIF Conversion set to convert to 16-bit, which is why you are seeing 16-bit output on the optical out?
