BTR7 Great Sound Why Am I Returning It????? 

Fiio BTR7 DAC AMP has great sound and many useful features it also has flaws that can be irritating and time consuming. If you want to use it just for a Bluetooth input it is great and will be a good choice. If you use Tidal and want MQA or files at higher resolution that require wired input there are problems that I experienced.

Let me know what MQA portable DAC you like or if you think chasing MQA is a silly idea.
I tried to use in the car with a 3.5mm aux cable output and the sound was noticeably better The car repeatedly wanted to connect my phone via Bluetooth and disconnected from the aux input making it a hassle and too distracting for the driver. This disconnect was the cars doing however it gave a clear side by side comparison and the BTR7 improved the sound.
The input can be bluetooth but the output is balanced plug or a standard headphone 3.5mm plug so you will be using a cord not matter how its set-up which is to be expected. It's a bluetooth receiver not a transmitter FYI.
Pros:
-Great sound
-Powers all headphones
-Bluetooth input connection is flawless
-Brings new life to basic headphones up to pro headphones
-Charges quickly
-On/Off switch for drawing charging power from your device
-MQA and Lossless file compatible
Cons:
-USB-C, USB, does not work every-time; it is very glitchy
-MQA on Tidal can only be accessed with wired connection and the wried connect doesn't work as it should
-Package did not come with lightning adaptor even though I paid extra for it
-The marketing says 'Leather Case' but the case is another material
-The App has terrible reviews
I did experience very good sound from the device. The connection troubles I experienced using the USB-C could be due to a bad wire but in that case the quality controls come into questions. I am not confident spending over $200 on this device and will return because it did not include the Lightning Cable which I paid for and because of these other issues.
Other options I am considering: Dragonfly Cobalt or Red from AudioQuest, EarMen TR-Amp, EarStudio ES100 MK2, HELM Audio Bolt DAC/AMP,
