Hello. I have had a fully upgraded Zishan, upgrade 5. Now I have D200+ ak4497. Zishan was really amazing for the money, but it can not compete with D200+ in any aspect, exept the number if file types it can play. D200+ has a new, faste CPU and there are no lags any more. But it cant play some .iso files that Zushan does. It has only DSD64 support. But in SQ, D200+ is absolute another class. In balaced mode it is more powerfull then Zishan DSD. In SE they are equal in power.
