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. I don't like extra step.I also can play Blu Ray or DVD-A through the HDMI into I2s.  But suggestions from other answers have me thinking like the DOB. Regardless the detailed, non fatiguing sound, is amazing. I should leave be and concentrate on some XLR cables as the system is balanced from the Venus to my Schiit Loki Max to my Mojilnor STAX Headamp then his modded STAX Earspeaker. No speakers here. Any suggestions for 1-3 foot XLR  below $500?

Stonyb3165,

I am not familiar with the Oppo connections and formats, so I'll be of no use there. As Soix mentioned I use a Denafrips Iris DDC ($550)  to convert USB from my streamer to I2S to the Pontus II DAC.....the Iris only accepts USB. Using I2S is a game changer in SQ, worth every penny. Does the Oppo output USB? Is it even worth it going this route with a decade old player?

The only CD transports that I know with I2S outputs are the Pro-Ject CD box RS2T, Nuprime (CDT 8 Pro, CDT 9, CDT 10), and the Jay's Audio units. I've tested the CDT2 MKIII connected I2S to the Pontus, and it was glorious......eventually what I'll end up with. I'd look at this as an option knowing you're up to date with current technology.

The OPPO has optical, co-ax, digital outputs. It has a USB input only. The HDMI will pass digital. I will keep this player until someone else makes a quality Blu Ray Audio/ Video, SACD, DVD=Audio, and for my large collection of cd's a buit in HDCD decoder, that only MEGA BUCKS Berkely Audio has in a DAC. NO player out there does all of those. To me this OPPO is priceless. I love owning disks.

My frame of reference for SACD players was one of the best ever built, the SONY SCD-1 which was modded my Vaccuum State to 5+ level. The D.BOB I mentioned is better in many ways to the SONY but the modded SONY still had a magical sound that could compete with new DACs. The SCD-1 died after 20+ years.

The fact that a $700 D.BOB and a $200 used OPPO, that I was not even using, can compete with the Sony is shocking to me. I had plans to get a SACD transport option for the DAC upgrade I had in mind. However, after the D.BOB I will use the OPPO as my transport and save the money.

My fav sonic disk is the SACD pressing of DSOTM, Love the fact that I can hear this disk again in it’s true glory. The OPPO also plays some SACD’s that the SONY had trouble tracking.

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.
