Hi all - happy to have found this excellent community. I've been reading for the last few days and the reviews and discussion here are top notch. I'm nearing some new audio purchases for the first time in a while, and I'm hoping to get some input on my best path forward.
I currently have two systems in separate rooms, but I'd like to move them into the same room and combine them where I can.
Stereo:
A few years back I built a O2 headphone amp with an ODAC in it and have been enjoying that with my Sennheiser HD600s. I've had the idea for a while that my next project would be building power amps, and this seems like a good time to do it. After some research, I think I want to use the Purifi 1ET400A modules. I'd likely start by building a stereo amp (or two monoblocks).
My first thought was to look for a pre/pro to pair with the power amps, but I soon learned the pre/pro selection is rather small these days, especially if your budget isn't over 3k. I did read the review here of the Denon AVR-3700H, and have considered it for its pre/pro abilities, but buying a massive AVR and not using the power amp section seems wasteful and less than ideal. I'm attracted to the smaller size and cool temperatures of Class-D amplifiers, so I'd like to keep my pre/pro section on the smaller & cooler side too, if possible. I'd have no issues feeding HDMI directly into my TV, but that would leave me with no way to output uncompressed audio as only optical out is available and I'd like to start using uncompressed audio on this system.
The best option I've found so far may be the Evolve II-4K HDMI v2.0 / Multi-Channel DAC. I could connect this to the HDMI out of my Roku (I rip Blu Ray discs to a media server and play through the Roku) and pass the analog out to whatever pre-amp I decide to go with. The disadvantage is I'd need one for any additional video sources and would max out at the number of HDMI inputs on my TV. It's also not HDMI 2.1. I do have a PC with HDMI 2.1 connected to the TV, but as the TV itself only supports HDMI 2.0, this isn't an issue for me currently.
From there I could continue to use the optical output from my TV for sources that only use compressed audio (eg satellite receiver) into a DAC of some sort.
The system I'm imaging would look like this:

- Rega Apollo CDP
- VPI Traveller v2 turntable
- Rega Mira 3 integrated amp
- Epos M15.2 floorstanding speakers
- LG C8 OLED TV using optical audio out
- Marantz SR5004
- Energy RC-30 floorstanding speakers

The system I'm imaging would look like this:
- Evolve II-4K for HDMI source with uncompressed audio
- Second DAC for TV optical out
- Pre-amp with input switching
- Purefi 1ET400A power amp
- 2 channels to start, with the possibility of adding a center channel and subwoofer
