Maybe you should put those caps back in you took out of your DAC. These caps are there for a reason and to remove them just because what you have read or you think it sounds better is not a good idea. You need to have some way to see the signal to see if it's a clean or oscillating signal. I have mentioned this to you in past threads about having a scope and to see what is going on with the changes you are doing.

Also you may be having oscillation from those I.C.s due to what you have done to that DAC.. Hiss is a good indication there is Oscillation somewhere in that DAC.

Try this, put those output caps back in and see if that hiss goes away. Some times the load of the circuit follow the output of the DAC (without those caps) can cause the circuit to oscillate. Also, try to barrow a scope to see what is going on.

You have done so much to this DAC, if you're not satisfied still then maybe it's time to look at another DAC or look else where in your setup.

Just trying to help you out! let use know your results!
