Satisfactory
The case is strangely devoid of ventilation, but I didn't notice any overheating during a day's use at 192 kHz. The three filters remain a mystery to me, I can't hear any difference between them, and the manufacturer is stingy with information on how to make the right choice. A single USB port is not practical, but it works perfectly with my Windows PC. The sound quality on Hi-Fi headphones is much better than with my old home cinema amplifier.
