It probably won't be better. The dac chip was not replaced by a research and development decision. There was a fire at the akm factory and the ak4493 chip is out of stock.To revive this thread, here a happy user of 4493 version. But it wasn't perfect from the beginning. All through trial and error. Devise is somewhat picky about sources. Windows 7 without updates and older android phones are especially prone to this. Some software tuning is needed wherever you have problems. For me it easier to use DAP as a transport. Both AP60-II and Fiio M3 Pro works flawlessly with Zishan. Sound quality wise, I think it's on the level of Xduoo XD-01, with nice warm tonality, contrary to Xduoo's neutral one.
Still thinking of 43198 version, maybe someone will post impressions to this thread? Will be much appreciated.
