Some problems are exaggerated. Yes, weak hardware is installed in the SE300. But this is a player, not a smartphone. In flash drive mode, it works smartly. But I'm 95% using only Qobuz/Tidal streaming services. It also works there without any problems. It cannot be said that it is very slow or bad. Update the apps manually. install the latest versions.
WiFi works well. Always a stable connection. After updating the firmware, I connected to Wifi5. If you have weak WiFi operation, upgrade your router.
Everything works stably. After the last firmware, it became more responsive. It cannot be said that there are any critical problems. All players have their own nuances. Judging by the price / quality / sound, the SE300 confidently takes top places.
In AK, over time, they may still improve their work, but they hope for global changes, of course, it's not worth it because of weak hardware. But in general, the player works well, there are no serious complaints and there can not be. And everything sounds great in general!
