Hopefully you have resolved this situation already. If so, please describe what you did to get this working. If not, here are my thoughts. I will assume you have the mini connected to your network and you are using the Android device to control the mini. I don’t know the expected outcome if you are streaming via Bluetooth. I expect you have the S/PDIF coax out from the mini connected to the SA8005 in.
If you have installed internal HDD/SSD in the mini and you have a high-res file on the drive, can you play it through the SA8005? Does the SA8005 show the correct sample rate?
If you do not have internal drive:
Music from Tidal will be 44.1/16 (generally.) Tidal MQA are encoded to 44.1 but may be processed at higher resolutions. You can change the mini to process MQA files. I have experimented with this setting and find it very reasonable. The link posted by @deuch is a great reference.
Connections: Network > Aries mini > S/PDIF coax > SA8005
Aries mini setting: MQA Playback Setup > MQA Pass Through = OFF
Aries mini setting: Decoding method = Auto
As a test, you might play:
the new Tal Wilkenfield. The opening track is 44.1 but 24 bit.

You didn’t say how you are “streaming Tidal from your Android device”. If you are using Bluetooth, then that’s your problem. As far as I know, you can’t use an Android device to run the Lightning DS app to control the Aries Mini, so I can only assume you are using lossy Bluetooth to stream from the phone to the Mini. I am also assuming that the Mini is Bluetooth capable since I have an Aries G1 and also an Altair which both have Bluetooth, although I never use them. If the above is correct, it really doesn’t matter what resolution music you are streaming as it will downsample the music to lossy Bluetooth. I hope this helps.
