I'm noticing a problem with MQA playback. When I use the USB connection to my PC, I can play back Tidal MQA tracks and get "MQA" on the screen. (As has been previously mentioned, the rate is always 44kHz, no matter what the track actually is). When I plug it into my Android phone and play with USB Audio Player Pro, even with it set to Bit Perfect, I can't get it to play back MQA tracks as MQA, only PCM. Changing nothing, I plug in an iFi Go Bar and I get MQA playback (and proper sampling rate display). Is there something on the BTR7 that isn't being recognized by UAPP? Does it need an update or something?

I'm using my BTR7 with UAPP on Android, and it plays MQA just fine. Are you allowing UAPP direct access to the USB device?

@FiiO, I don't seem to be able to find these numbers published: what is the power output at 600Ohm via BAL? Ideally, both in mW, Vrms and mA? It would be also good to see those numbers with the BAL boost enabled.
FiiO only ever (officially) measures and posts power output measurements in 16 Ω, 32 Ω, and 300 Ω, both for single-ended and balanced (where applicable).

I had the same problem. MQA not working on pc or android with Tidal. I unplugged my headphones and plugged them back in and MQA now shows up in the display.

Oh, for crying out loud, that was the problem. I was testing without headphones plugged in. I'm not sure why that makes a difference, but once I plugged some in it magically started showing MQA. I'm not sure what's going on in those circuits, but thanks for pointing me in the right direction!

Don't feel bad - same exact thing happened to me when I first got the BTR7... :)

Dear friend,

Sorry we do not have the output power data for 600ohm headphone and it may be hard for the BTR7 to drive the 600ohm headphone.

Best regards

Dear friend,

Yes, in order to detect the playback, you would need to insert the headphone first before playing the MQA file.
Here is a video for your reference:

@FiiO Does the BTR7's Wireless Charging Charges the Device Fast enough to be use while Charging wirelessly?

:sweat_smile:
My BTR7 was at 80% and I put it on my Samsung wireless charger. Listening with LDAC for about 10 minutes the app read 100% and the bar on the BTR7 screen was full. Still 100% after 30 minutes.

Is there a DAP equivalent to the BTR7?
