Is there a DAP equivalent to the BTR7?
FiiO M11 Plus or M11S would be the closest. Both have similar design language to the BTR7 but sonically the M11 Plus would be the closest due to its THX AAA-78 amps 🙂

Oooof, the S is more than triple the BTR7 and the Plus is more than quadruple it :/

Suddenly, the BTR7 feels like a bargain... Was thinking of returning the BTR7 and getting a DAP to make my entire music situation simpler (currently copying all my music across 3 devices) but if that's the cost, I want none of it xD

I own an M11 plus, sonically the gap between it and the BTR7 using the LDAC codec is not as wide as you might think.

Is anyone else having issue whereas wireless charging stops before fully charged? My wireless charger starts blinking red instead of steady red midway

I'm gettin a splotch of white pixels above the volume occasionally that only disappear when I turn the btr7 off and on. Anyone else getting this? Wondering if it's a firmware issue or whether should I return and get a replacement? @FiiO , Input appreciated . Will post a photo next time it happens

This is not a quality issue , The qcc5124 is not a powerful Soc so sometimes the data for the screen can't not be reset as soon as possible .

@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.

for high impedance headphones, usually you can calculate the output power by yourself .

the output power = u²/r, so the power for 600 ohms will be 1/2 of 300 ohms, which means BTR7 can output

40mW/2=20mW.
