This is a review and detailed measurements of the BerryBak BEA1 Bluetooth Receiver with support for LDAC and USB DAC. It is on kind loan from a member and costs US $46.90.
The metal case is fine, albeit I am not a fan of its very sharp corners. Functionality is excellent with support for RCA outputs as you see, and digital outputs on the other side:
That is the taller antenna. A shorter one is supplied which should not rise above the case.
While not very clear from the instructions, the USB connection not only provides power but also exposes the device as a USB DAC.
BerryBak BEA1 Measurements
There are a lot of similar looking measurements but hopefully you can stay with me.
First, I tested the unit as a USB DAC and tested its analog output:
This is pretty bad results especially since it also clips (severely) above 1.4 volt (max is like 2.4 volts). Switching to Toslink output only shows 16 bits of performance:
The main event is LDAC Bluetooth codec streaming though so let's see how it performs first with analog output:
This is streaming from my Samsung S23+ Android phone configured to produce 24 bit LDAC stream. We see that the analog stage is the bottleneck and not LDAC. So let's switch to Toslink digital output:
Now we are talking! Notice how the output rate is changed to 96 KHz so the high-res mode is only supported with LDAC streaming.
Here is our dynamic range which even with analog out (surprisingly) is good:
Translation: if you connect the Toslink to a reasonable DAC, you should get excellent fidelity, rivalling wired connection!
Just in case you are curious about other codes, here they are with Toslink Digital Out:
Aptx: (default in many devices)
Notice how the device is now outputting 44.1 kHz.
AAC:
As usual, AAC which is normally an excellent codec, shows up horribly in Bluetooth envelop. It also sounds bad to my ears. The best of the non-LDACs is SBC to me:
But they all pale in comparison to LDAC.
Conclusions
Let's get the bad news out of the way: the analog output of the BEA1 is horrible. Even the digital output is deficient if you use it as a USB DAC/digital bridge. But switch to LDAC streaming and use Toslink and the device delivers nearly perfect output with a single tone. In my past listening tests, LDAC is far superior subjectivity to other Bluetooth codecs and these measurements show it again. A single tone should be very easy for a lossy codec to handle, yet, all but LDAC manage to screw it up good.
If your application is LDAC in, and Toslink out, then the BerryBak is recommend. If you want analog out, then it will be disappointing no matter what.

As always, questions, comments, recommendations, etc. are welcome.
