Oh yeah, the days of Shanling's big Hi-Fi machines. We are still making them, but sells are pretty much all limited just to China. Hopefully it will change next year. Little bit tricky to say to be honest. Run with 16/44 and just as music player? Around 11-12 in single ended and less than 10 in balanced. Streaming over Tidal, changing song every few minutes? Or playing DSD256? That can cut it by few more hours.
