My server is up to date: all other devices and Android based DAPs are able to connect to my server via ARC.

As am I and I have no issues with the 3000T connecting.

Did you try the proverbial uninstall/reinstall?

Also, since ARC is whitelisted, did you try to sideload the latest ARC apk (1.060)?

Edit:
Try rebooting your core.

Hello @JasonNYC ,

Do you know if there is a more recent version of Roon ARC that can be uploaded to the servers? the latest I have (1.0.59) stopped working.

Thanks in advance for any help and/or suggestion.
I'll let the team know to push out the newest version.

If you don't want to wait, you can download the latest version of the APK directly from Roon and just copy the APK file into the OpenService folder on the player and install it from there. Here is the link to download Roon Arc from Roon's website. Download the Android APK - https://roon.app/en/downloads

Can confirm no issues with Roon Arc 1.0.60 on SP3000T and SP3000M using the APK that I downloaded directly from the Roon website and manually installed. I also asked the team to push it out to the download server.

Thank you Jason!
I'm on RoonArc 1.0.54 and Download indicates version 1.0.59. When I try to install that version there is a parse error "There was a problem parsing the package". I can see there is a RoonArc.apk in Downloads. Deleting and downloading again or restarting did not help.

Guys what it is the best method to transfer files to SD card from Mac M-based computers? File Drop is quite cumbersome as it requires FTP, USB connection isn't working out of the box either. Windows integration is a lot better IMHO, but sometimes I need Mac and removing constantly SD card to add files isn't a good solution either. Any tips please?

Android file transfer app. Works very well... https://www.android.com/filetransfer/

Unless I'm only doing a couple albums, I always remove the SD and use a microSD USB C dongle to transfer files. I've done that with all my android based DAPs. Android File Transfer works okay for a couple three albums, but isn't ideal.

With the internal SDXC card slot of the M3 MacBookPro. First I formatted the SD card with the disk utility SD EX Fat and then copied my music data - it worked perfectly.
The second option is the Android File Transfer, which also works with that. When you connect the AK to the computer, it starts automatically in the background, where you can select the internal memory and the SD card and copy your music onto it.

Now the second attempt with an AK 3000t and this confirms the behavior of the battery.

Firstly, in my opinion it is undersized for the power consumption of a mobile device equipped with tubes, a more powerful model should have been chosen. Up to 30% per hour can be used here if you select the appropriate files and options, actually far too much. How long you can then enjoy your music is easy to calculate and this is in stark contrast to the factory specifications, which are probably only based on the minimum solution in order to be able to achieve this but will certainly have a negative effect on the enjoyment of music.

The second thing that is also confirmed here again, even when switched off the battery sometimes loses some power, but this seems to vary and at least to be kept within limits.

One positive thing is the new battery protection function, which can limit the charging limit to 85% and protects the battery if, for example, you are using the device for a long time. It takes a long time to copy data to the AK using a program or use it with the DAC.

One more question - is there a way to transfer missing album covers? There are some in my collection where no cover is displayed even though the data I transferred did have one.

The Woo WA8 barely lasts 3 hours for reference. The Woo tube mini uses the same tube as the 3000T and drains the source device rather quickly as well. You will not get 10 hour battery life from any NOS tube DAP. The 3000T is a brick already. Adding a bigger battery pushes it to transportable from portable. AK states the 10 hr battery life is with volume 50% and OP amp mode. I read that in a review. Even my nutube based DAPs barely last 4 to 5 hours.

One more question - is there a way to transfer missing album covers? There are some in my collection where no cover is displayed even though the data I transferred did have one.

You need to add a folder.jpg or cover.jpg file to each album folder. MP3tag has a batch file function to accomplish this. I find that only DSD, WAV, and AIFF files need the folder.jpg file. I just put the SD card in a USB C dongle to do this. I find it the easiest method. YMMV
