What cable do you use for the Direct Stream DAC I2S input? I am connecting my CD transport (Jay’s Audio). I understand that most HDMI high-end (=expensive) cables are optimized for video, so not sure what to look for …

If you’ve seen their modification it changes the cosmetics of the cable. It is much simpler to just get new screws from Ace Hardware and get a standard cable. Cost of the new screws are probably around a dollar.

I was wondering about the quality of the modification, do you know the screw replacement size etc?

I don’t but magister or one of the other members who changed the screws should know or just take one of the screws with you to Ace and let them match it up.

Do I2S cables plug in all the way? I notice that whatever I plug an HDMI cable into to that the connector remains out about 1/8 of an inch.

Sounds like you might have the mk2 screw head interference issue to cable connector too! My homemade i2s shorting plugs have that problem. They can be easily loosened.

I think that the Tubulus revision is not just about the screws, it also changes pin19 that was causing the DAC to show a red light instead of green.

I agree but would have them make the Mk 2 pinout change without the cosmetic change. Screw change is easy and keeps the look of the cable standard in case of need to re-sell.

Screw change is easy. Can I assume that no internal access is required, just replace the screw externally?

Yes, it’s external. Just be gentle when you put in the replacement screws.
