Add I2s to Oppo players?

Sorry I am not clear. The only source is the OPPO. So far.  I use the optical to the DAC and the #1 OPPO HDMI output to a cheap box that extracts digital from SACD's ,because DSD will not come through optical. The extracted signal from the black box goes into the Venus II I2s input

You have multiple very bad issues going on here.  My initial more thorough response got kicked out once so I’m not gonna go into more detail here now again, but you’re very confused and not getting near the best from your excellent DAC.  You have some work to do.

I’m really trying to help here, but A’gon keeps kicking out my responses so right now I’m beyond pissed off.  You should not be using optical connections to your Venus.  You should not be worrying about converting HDMI from your Oppo to anything.  Your priorities are all messed up and you need to totally rethink what you’re doing here.

My BrystonDAC3 has HDMI inputs and I output the Oppo 105 DSD from SACD into it

Denafrips told me not to do this, but I might try this, as I can do the same.

Thanks, I had been thinking about trying this.

Oppo seems to be geared toward HT, reading DVDs.  So 2 channel sound is probably a low priority.

I2S is mostly a fools errand in my opinion.

Is USB an option?

Maybe you just need a 2 channel CD transport.  My CD transport is 5x as costly as my HT DVD player.
