Every dc blockers and balanced transformers I ever used suppresses transients and dynamics, particularly with amplifiers.
So all the reports saying this device not doing that is exciting. A foil inductor for power conditioning? Very interesting.
@alvin1118 going by internal pictures you are doing a stage of filtering for each 2 outlet receptacle? This means adding a third receptacle (to get 6 outlets) would be difficult?
Perhaps you could make the boards modular and have them in the chassis sideways, so the Tai Hang could have 4/6/8 outlet versions?
