    I actually just put the pi itself together for the first time, with the 'official' screen, and there - they refer to the long wires as 'jumpers' so I was definitely confused.

    But so I take the cap off and just leave it somewhere? And if I don't take it off I don't need the separate power supply for the pi itself?

    Yup this is all correct. Keep the jumper safe in case you change your mind in the future, they are easily lost. I may be speaking from personal experience. ;)

    But fear not if you lose it. You can buy several hundred for under 10 bucks.

    Done. Also a chance to wipe and buff the plexiglass. For some reason all the pictures I've seen in the wild it has like fingerprints and pizza sauce all over.

    Anyway. Is there a right order to connect/disconnect - which do I plug/unplug first - the pi or the hat or doesn't matter?

    It could probably work either way, I’d start with powering up the hat to ensure it was ready when the OS booted up.

    Pizza sauce on the case increases audio texture by 10%. Fingerprints are just ugly and inevitable.

    In the old days, we'd put the cap back on a single pin (leaving the adjacent pin uncovered). That way, its right there if we need it in the future

    I was not able to use gpio gpio24 as when switching off *pwr_sw (pin14) it seems that no time is left for any signal and shutdown.. pi2AES power the Rpi as i did not found any improvement with minimal piCore player using dedicated dedicated power supply for rPi.

    Working with Mute (pin4+pin3 -> gpio27) with push button to shutdown, I also added a switch on pin 13/14 to unpower the Hat. Modification of shutdown scipt will allow me to call a wifi switch.

    Just have to configure shutdown gpio on piCore web interface and install monitor... No need to install python library or any additional extension...

    Good day, I pop in every now and then, originally came here for this streamer. I purchased mine almost 45 days ago, and I know they are super slammed. So it will arrive eventually. Guessing in a month or less I hope.

    Could someone please tell me what operating systems this unit can use, am I able to use roon on it? or only volumio or how does it work. Appreciate the help.

    It's really the player software, the base OS is probably similar or the same for each. Popular options are MoOde, Volumio, and Ropieee (especially if you use Roon). It's easy to flash a player onto the card and play around so you may find it worth trying all three to see which you like best.

    coax is unbalanced, no?. but the board has a balanced output, and the dac has a balanced input - how do I utilize that?

    Coax is digital, balanced is in the analog domain. The digital signal sent by the Pi2aes via coax has separate left and right channels.

    ok I may be not understanding some fundamentals here.
    Why do people go above and beyond to build balanced chains (source>dac>amp) if you can just use coax?

    There's no such thing as balanced digital. You can go balanced out of DAC, preamp and, amp. You can't go balanced into a DAC.

    AES is balanced digital, so is I2S via HDMI

    Is ropie free?
    I believe volumio is, but excuse my ignorance I am not very familiar to audio in general and also very new to this, just about a year in. I use quboz primarily, I believe volumio does support Quboz, would it better to use roon or just volumio and quboz.

    I do not have roon yet, but I am planning on getting this black friday trial and test it out. I also want roon cause I think it has internal EQ which can be beneficial. The other software may also have EQ, I do not know. I am currently using equalizer APO, but I believe I am not using it correctly cause it's not really doing anything when I turn it on or off, via headphones or speakers. I have it installed on all my output devices.
