Last night I built linear power module for upgrading OPPO 93 visual and audio performance.
This module is 100 % same size and dimension of original OPPO SPMS power board.
It is very easy to install .
Just plug 3 cables and tighten up 5 bolts as shown in picture.
Contrast is much improved, color became richer, video noise and edge became much cleaned.
audio performance is also improved.
I would say PQ of this unit is 75 from 40 ( original ) , audio is 80 from 60 ( original).
I used coaxial cable for audio connection to my AV peocessor.
JVC X-3 3D projector with 110 " for video evaluation.
