WLS - I put it into cases
Hello members,
I put my Waynes-BAF2018-Linestage and the PSU into cases.
Dual-Mono in two cases. Each channel has its own PSU.
You will ask: 'Where is the volume pot and input selector?'
Answer: 'In another (third) case...'

OK, let's start by not discussing matters I know little about, like how that galvanic isolation between the DAC and the Pi happens. I would love having more information about it, even if my present setup did work fine for some time, using the Topping D50 as DAC, through USB. So mine or yours seem to work.
What I did love in your system was that screen you put up front with the VU meters, which seems to have some play control that resembles an actual player, which I missed on the simple remote I was using. You know: play, pause, stop, rewind, fast-forward. I miss that on my Nvidia Shield and on regular TV Android boxes.
The reason I picked picoreplayer was because it seems to be the only one that doesn't rely on a cell phone for remote controlling, which I definitely do now want.
I will need to get back to it all, and assemble the system again, this time with Windows 10. I'm slowly moving from Windows 7 to 10, and I had some issues that now more or less seem to be solved.
Now, what did the Wayne's preamp add to your system in audio quality?
What power amplification are you using?
The other path you described, with AMB system, seemed another thing I might be interested in. If I could adapt it to be used as a 5.1 or 7.1 HT preamp. Do you think it's possible?
Obstacle ahead: wanted to do the input connection, but single ended...
I think it is just as Wayne explained (#263, https://www.diyaudio.com/forums/pass-labs/329240-waynes-ba-2018-linestage-27.html#post5699074 ), but this surpasses me—R17 being deep inside the pcb, am I really supposed to feed the minus in there?
No shortcuts (connect ground to both in- and gnd or something)?
Thank you!

Have some fun and take some risk! Score the PCB with a utility knife but don't cut it all the way through. Then tape the board to a tabletop or countertop, such that half of the PCB and the score-line are hanging over the edge, out in the free air. When it's in position, give the board a swift karate-chop to break the board right at the score line. And enjoy yourself! It's a hobby, it's supposed to be fun.

Will this help? Here's my working preamp (in my rudimentary test bed amplifier chassis). Hope you can follow the wiring (it is single ended). I included a wiring diagram too just in case. You can see the inputs (RCA's out of the chassis) and output (installed on the chassis). Offset was about 0.4mV.

Nope, would have to improvise—something similar to how the purple boards were mounted...
If I understand correctly, CN3 connects to one side of R17. The [IN-] boxes on the schematic are connected to each other, but the line isn't drawn between them because it would cross a lot of other lines and make the schematic more cluttered. This notation is similar to how a schematic may show multiple unconnected ground symbols to make it more readable when connecting them all with lines would make a mess.
Of course I could have totally misunderstood the question.
I‘m convinced that it is not that complicated. Wayne was talking about the purple boards, those we’re working with got things changed (this is how I understand 6L6)
And I believe he did the same on his ba-3 but reversed the decision...
