As far as I know Topping 90SE and Gustard X18 are designed on the same chip? Right? Why then 90Se is DSD1024 rated instead of Gustard which is DSD512 ?
Yes, that's correct. I do understand it on the same way. But my post was about SU-9 DAC.
Actually I'm looking for external DAC which can take MQA from Coaxial. If I don't find such, probably I will go with RME ADI-2.
I apologize for interfering the topic but I am in the same lane.
Just need a DAC which can unfold MQA from Coaxial or Optical input and better than internal one of Bluesound Node 2i.
