Add I2s to Oppo players?

I do not like the idea of using a box to convert the HDMI from the OPPO to I2s. And it does not lite the DSD on the Venus II. Denafrips says there is a problem with the conversion. I cant go HDMI straight from OPPO to Denafrips, I am told I may damage the Venus II . The I2s lite does illuminate, but not DSD. It sounds great, but if I ever want to stream at the higher rates from a computer I will use USB of course. I just don't like the idea of a $40 Chinese box between the Oppo and Venus II. As OPPO does not makes the universal players anymore something might wear out. As good as it is, and my player was N.O.S. when I bought 2 years ago I pray it will be ok. It gets its AC from a PS Audio Power Plant 15.

 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.

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?

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.

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.

Agreed its not recommended to go direct to the Denafrips from OPPO. One HDMI channel can be set to digital audio onlly, no video. I will message Alvin at Denafrips again for more clarification. He has been most helpful. Better than any other company rep except maybe Birgir at Mojnir Audio. I was disappointed with my contact at P.S. Audio- not Paul. As I have stated, I am hardcore disk listener. Some of my DVD-A do sound better thru optical. And again, Optical does not pass DSD, so I need HDMI to I2s. My leftover budget is for 4 powercords, and XLR to go between them.
