Would it be possible to connect a Raspberry Pi (say running Ropieee as a roon Endpoint) via HDMI to the D400?

That page need to be put on a blacklist to protect clueless people. Amazing what kind of utter bullshit they are able to come up with. Take a look at this reference gold network cable for $700, lol but there is a signature level LAN cable for $1300 as well advertised as the best "sounding"...

You are absolutely right. As soon as I saw this, I exited...

XLR carries balanced low voltage signal, i.e. per channel + and - and the 3rd pin carries the shield (which if properly implemented according to the AES, connects source and receiver metal cases together). Passive speakers have just two connections (going directly or through a cross-over) to...

Passive speakers have only + and - on their inputs, they don't have "balanced" inputs. They become balanced if you connect the + and - to a balanced power amp, and single-ended if the - goes as return to ground to a single-ended power amp. Active speakers always have their amps build in. And...

Of course it makes a difference, you are correct. High powered speakers are usually driven by power amps placed near the speakers keeping the loudspeaker cable short, or are active, with dedicated (multiple) power amps for the different chassis, placed inside the cabinet, again keeping the...

Yes, it makes a differences. Also headphones can be connected balanced as well. And this works best if you have a balanced headphone amp (four channels for stereo). In this case 4 cables go to the headphones, 2 per channel for + and - directly to the speaker. In this case the signal doesn't...

No, its not. Cause XLR analog and also speaker cable is not data, but analog. Know the difference between resistive and inductive load and what it cause in the analog domain?

Really? EE degree and more than 20 years of experience in electronics. But I save the explanation, cause you're not going to understand it anyway. Ever thought about active speakers, probably don't know either why they exist in the first place.

Should be the opposite. Unless you have mono blocks with high damping factor and easy to drive loduspeakers, it is always preferable to use long XLR cable runs and short loudspeaker cables. The shorter the loudspeaker cable, the better the amp controlling the speaker. One of the reason why mono...

A differentiation should be made: 1. is the equipment in place fully differential, i.e. 4 internal channels for stereo, or 2. is the equipment single-ended internally and balanced XLRs cables are used only for interconnection. You are basically commenting for 2). With 1) using balanced...

Now we need someone to add internally a slot for a Raspberry Pi, which then will add a network port to this DAC... and make it instantly roon/LMS/Volumino/etc... ready!

I see. Would be easily though to use a passthrough connector for the Ethernet on the Pi instead of not using the PCB mounted connectors (shorter signal path). As such the original version with both RCA and XLR was just spot on. Any other differences between the original version and the new one?

Are the outputs buffered and can the main XLR and the out on the green terminal output at the same time?

What is the original purpose of the terminal blocks, to have a 2nd XLR out? I see there are 3-pins in there as well for a differential signal

Any plans to include RCA out in addition to the XLR out on the PecanPi hat? I need both outputs to be there and the adapters are not a solution for me.

Why did they omit the RCA out on the latest version? I would have immediately bought a couple of them but I need XLR *and* RCA out on it. Anyone know any plans they might have to include the RCA out as well?
