Here's a new thread for all the pictures I'm going to take to show in detail how you can transform your Lite DAC-AH into one of the world's most dynamic NOS DACs - Ozone
Once you take off the lid of your DAC-AH (8 + type screws to remove) you'll see this within :
The PCB (to the left of the R-core transformer) divides logically into three areas, bottom to top. First the digital input receiver and digital power supplies. Moving upwards we have the DACs themselves and finally, at the top the output buffer stage with its own analog power supply.
Getting the PCB out of the case turns out to be tricky by virtue of them having used hot-melt glue to secure the S/PDIF input connector. So you'll probably have to sacrifice this (its the lowest quality component in the whole box, so no big sacrifice there) in order to extract the board from its case. Remove all the + type screws securing the back panel and the torx-headed one on the optical input unit first. Also desolder the L,R phono output wires. There are three + type screws fixing the PCB to the bottom of the case.
P.S. I also want to mention - because this is important - that you're seeing this development almost in real-time (just a few days behind) that there's some risk involved that the DAC (which works fine on top of my speaker) won't fit inside the case with the additional filters. Or that it won't fit without incurring some hum from the trafo. Just so as you know its not a total slam dunk at the outset and if you also want to follow along in real time there's that slight risk
