it will have different for sure since u have nice equiment ....but u should know what u need and what kind of sound or which part u wanna improve first .
Buy a better PDU (拖板) with filter. Plug all original cables of your video equipment (TV, BDP, STB, etc.) and see the difference. Plug those of Amplifiers, subwoofers to a PDU without filter. You will realize the improvement and get poisoned.
Next, replace cables of your equipment one by one and see the difference bit by bit. Enjoy the process.
