Long time lurker and only today plucked up the courage to make an account and ask a question. Apologies in advance if this has been asked and answered before/elsewhere. I am currently rocking a very - very old AV receiver and am considering moving on to the Denon 3700 (4k/120 is not relevant to me), with external amplification for my 5 channel setup. One of the things I am looking into is DIYing either a triplet of mono-block or a single 3 channel purifi amp for the LCRs - with suitable input buffers (if that's the right term) to enable the RCA ~2V outputs from the AVR to drive the amp(s) to full power. I have tried to read through the Purifi DIY thread, but got very quickly lost.
I recognize that this is not easy/convenient DIY - but it's a thing I would like to experience doing if feasible. Hence my humble request for guidance to the people on here who know much more than me. Even if it is to say I really shouldn't be trying it
I think there are bits of the puzzle I have google-figured out, but I suspect I am missing the forest for the trees. Essentially - I believe the key components I need would be

- Purifi modules x3
- Input buffer x3 - I believe Neurochrome sells these for my use case - i.e. support lower voltage - unbalanced inputs
- Power supply(ies) - such as 1x SMPS3kA400 or 3x SMPS1200A400
- Cases - I see Ghent does a case for the eval but none for monoblocks - so no idea how one goes about adapting a bare shell to one's requirements
- Heat sinks
- XLR/RCA inputs/selectors
- Everything else I am clueless about.
