Great job!

Did you tap the heatsinks (between the fins) for the amp/psu mounting screws or screw/nut them?

The bottom of built in amp board heat sink has drilled and tapped hole, I just drilled through holes in the heat sink to mount the amp board,

Layout for the holes is in a doc on 3e Audios web site,

You can see the hole drilling drawing I am working from in the photo below,

For the power supply, it was through holes and machines screws, washers, lock washer, nut.

Curious to hear your sonic review. I know all the accolades of TP3225. Tried early module but think I experienced the current limiting. Then later tried the Fosi ZA3 that youtuber's tout. Overall when I tried them, while was impressed by the mid an upper range smoothness and detail, I felt like there was not much punch. Perhaps that is from my early experience distorting my perception. Curious to hear what golden ears say in an unbiased discussion - i am really starting to hate social media, like what can you trust anymore.
