I had a Brookly DAC and was very happy with it. At least in the first few years. However, after a few years, more and more pixels of the OLED display began to fail. Just under two years ago, strong distortions began to occur in the audio output. At first it was rare and the error only lasted for a short time. Later, I had to switch off the DAC and it worked again. And soon after, the disturbances occurred permanently. So the search for a successor began. Its predecessor was an Antelope Silver. It still works. And I wouldn't bet that I could identify it blindly from the Brooklyn (before the fault occurred). The Antelope was unfortunately limited in resolution and did not understand DSD. After some time of research, especially at Audio Science Review and at Archimago's Musings, I risked the experiment and bought a Chinese DAC. It turned out to be a small SMSL M300. I chose it because of the features I wanted. In terms of sound, I expected it not to sound and to reproduce exactly what is in the data. If a manufacturer masters the technology or implements what the manufacturers of the converter chips specify, it is possible around 100$ (like the Topping D10). If DACs are more expensive, they may have their own sound. But these are more distortions, which some assume would be the expression of a better sound.
I became critical when I read that the Brooklyn Mytek was fiddled with in this way. If you switch from digital to analogue volume control, the DSP adds K2 or K3 distortion to make it sound more analogue... I couldn't hear the difference, but my confidence in the "most authentic reproduction possible" was shaken.
If your Brookly is still working fine, I would sell it. The life of the OLEDs is limited and without a display it is difficult to change settings. The failure of the audio part is probably an isolated case, I haven't read about it in any forum. Topping, SMSL and Loxje are the manufacturers who have mastered the technology, have sufficient quality and are still reasonably priced. Gustard and Matrix would be excellent manufacturers at a higher price.
