My 4 friends and I all finished the modification following Nick's installation directions. Thank you Nick.
Including G68XXV*2, 861v2*1, 861v3*1, 861v4*1 and 800*1.

The improvment is quite noticable, two friend of my even sold the original switch PSU.

The improvement mostly on bass dynamic and sound field, Now I so enjoy with my system.

Btw how is your modded Oppo93 worked? That may my next move.

Thank you Nick again!
