Well after two years of designing and prototyping I finally have arrived at my Integrated Amp. What was supposed to just be a "remote volume feature" turned into a minefield i.e. display, remote control, source slection, soft start, standby, DAC, IV Conv, volume control, DC offset protection, speaker protection, over temperature protection, fan control, bluetooth, WiFi and the integration of a RPi 4 for hometheatre or an up2stream...😱
As I wanted to do some comparisons between different amplifier types I created four different amplifier modules which are interchangable i.e. the mounts are the same: 1) Darlington output based on NP AB100, 2) BJT Output based on the HoneyBadger, 3) LatFET output based on Goldmund and 4) MOSFET of my own design.
There are a few things I need to do for the final pictures but hopefully the attached gives a feel for the amp. Just the rear back plate to drill/cut and then a thorough clean.
If there is enough interest I may tidy up my horrendously looking schematics and post the gerbers.
Cheers

Nice work! You really "dove in" with this project. I for one would be interested in your implementation of almost everything in your minefield. Don't spend a lot of effort on schematics just for my curiosity though. I appreciate what you've already posted. It gets the gears turning. Thanks for sharing.
