While you have the amp open, I'd suggest try putting some damping material on the power supply caps.
I'm contemplating the same thing. I was considering replacing the OEM Filtered PEM Shurter with a non-filtered F'tech PEM as well. I posted elsewhere some time ago after reading of potential filtering pole conflicts buggering up the sound. I currently plug my D200 in to a RSA Haley, but after picking up a Triode Wire Labs Digital American pc, I was intending to go straight to the wall outlet (A F'tech GTX-D®). Time to experiment some.
I'm still noodling around trying the WA Quantum chips. Sprinkle a few on the DAC and Power modules, and the PS Caps. Both in the D200 and my Aurender S10.
