The WM1Z now has BT receiver mode and is able to handle connection in SBC, aac and LDAC, but you won't be able to use Tidal offline on it as it is not an Android based player.
If you want a stand alone device that can do Tidal offline, I guess the new AK players (SPK series, SE100 etc) which now supports direct install of APK via the Open App utility might be a better choice.

Thanks. Any idea how the 1A compares to the Z?
Only hear it on battery. Thanks!Assuming this is only when you have power connected to the KSE amp, it could be due to your power supply. You may want to consider a low noise linear power supply from one of many on eBay. If you hear the noise when using battery power, then that is not normal and I would contact your Shure support center.
