All of the HDMI to I2S cards from that end of the world have the channels reversed, so presumably none have been tested with PS Audio eqpt. Sounds like you got a bad card. I did too initially and Jaehong sent me two to make sure one worked, which the first one I tried did. There is another to me much more important SQ problem, but it’s not clear whether it’s the cards or the DirectStream with I2S. There’s a discussion on another thread about that. Note that someone with a streamer also experienced the same problem discussed there, which suggests the source of the problem may not be the cards but the dac - I2S sound: What to expect?.
Update: I just go an email from Jaehong that says a new batch of cards with the channel reversal problem corrected will be available at the end of the month.
