I was just going to say that your OPPO likely has a preamp with volume so you need to set that to fixed and use the volume control on the KRELL. Looks like you solved that. I actually had the same issue this afternoon with a headphone amp and DAC. When I reverted my DAC to FIXED volume I set the DAC's volume to infinity (or no sound). I am not sure that is needed but I thought that was the correct thing to do.
So now you are not getting any volume from S2 even when you change the volume on the KRELL?
Have you looked at the Menu setting on the S2 input. There is a wealth of settings on the Menu for each input. Take a look at that to see if anything is disabled. I found the menu easier to use with the buttons on the KRELL unit, not the remote.
I was using the same inputs myself and did not have any issue so I am sure we can sort your situation out.
Let me take a look at the manual and get back to you. I moved my KRELL to my sons play area so I only have 1 DAC input being used (the NETWORK input).
