Add I2s to Oppo players?

 As DSD from SACD only 64, I will just use the optical input and get rid of the cheap box. The Venus II is far beyond my expectations for DAC for the cost. Sitting in the middle of Denafrips line it has all I want and nothing I don't. {except 2 optical inputs.The impressive construction, and design along with price is what I settled on after months of looking. SACD is nice, but some BLU-RAY's  and DVD-A are incredible as well. No Regrets.

I’m honestly having a hard time following what you’re doing as the info of your system has come in piecemeal, but if I’m reading right you’re still using a computer as a source into your very nice Venus DAC.  If that’s the case that should be the first thing you should address and add a dedicated streamer that’ll up your performance significantly.  Likewise, adding a DDC and converting to i2S is another area for significant sonic improvements, and I’ll call on @vthokie83 yet again as he can tell you his experience upgrading to i2S with his Denafrips Pontus II.  FWIW.

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.
