    Thanks!

    Oh, can I just insert the card in that DAP and format it that way?

    Thanks.

    My situation is that I travel to work on the London underground. Sometimes I want to watch a movie etc on the phone without having it directly connected to the DAP/headphones as the tube gets very busy and lots of cables are a real pain.

    My SP1000 CU isn't reliably shutting down after 30 minutes of inactivity. Under the below settings I assume the device should automatically shutdown after the music has stopped playing and 30 minutes has lapsed. Does anyone have advice? I'm running the latest 1.17cm version.

    Timer settings
    Auto Power off-30 minutes
    Screen timeout-1 minute
    Sleep Timer-Always turn on

    No, you need to have a USB adaptor/reader that you can plug into your computer and format it there (FAT32).

    Unfortunately, it sounds like it will need to be sent into your local service center to be checked out and serviced. I will PM you for more info.

    With such a small collection of DSD music in the genre that I mostly enjoy. I purchased a Sony PSH-X500 turntable, this allows me to rip vinyl to DSD and play them back accordingly. The internal A/D converter supports native conversion from analog to DSD 2.8 MHz or 5.6 MHz digital.
    The vinyl versions of the music in comparison do sound different, better to my ears, and I wanted to persevere those difference via DSD. I have been ripping all the new Rush re-issues from 2015 remastered. So far I have thoroughly enjoyed doing so. Like anything in this hobby, it's a labor of love. I am having fun listening to them on my SP1000 stainless, converted and enjoy the difference I hear, its there

    I had the same problem with my SPKCu last year.. sent it to A&K (through my dealer) and they replaced the power management IC.
    The whole process was quite fast although the unit had to be shipped to South Korea.

    I’m not sure but it seems like you should turn off that sleep timer

    I also have another question: When I enable MQA on the SP1000SS in the USB settings, my Audivarna shows "No MQA device detected" , any idea why that is?

    Also, when you say you enable DoP settings in Audivarna, are you referring to the native DSD compatibility, and are you setting it to DSD over PCM 1.1?

    Finally, do you prefer Roon over Audivarna? I hear people tend to prefer it.

    No news on a possible SP1000 amp.

    SP1000 is not a MQA renderer (when used as external USB DAC), that is why Audirvana shows "No MQA device detected". It means SP1000 cannot fully unfold MQA encoded file.
    You can play with MQA Renderer/Decoder setting. The first unfold will be done by software - Audirvana, but SP1000 cannot unfold the file to its original.

    I think SP1000 can fully unfold the MQA encoded file if you have it stored on the device (I am not sure about Tidal streaming MQA file) - correct me if I am wrong.

    See my screenshot below:
    Original file is 24bit 352.8kHz (see top right corner)
    On the left top corner you can see that Audirvana unfold it to 24bit 88.2kHz (Audirvana did first unfold, SP1000 cannot unfold it to original 24/352.8)

    Regarding second question - yes DoP settings are related with Native DSD Capability. I have got it set to DSD over PCM standard 1.1.

    I’ve found if you use a program such as mConnect to stream to SP1000 a Tidal MQA file, then it shows it completely decoded.

    Awesome man, I really appreciate the help. I know I asked many questions, but i'm somewhat new to the HiFi game, so i'm still learning the ropes. What kind of settings have you found to work well with your device on the Audio Filters page? Do you use any upsampling?

    Also, i've been thinking of switching over to Roon. What do you think of Roon compared to Audivarna? I hear many people prefer Roon.
