    Thanks coin777, I did it, W2 Jumper is out. Pi3B+ is using iFi Power X 5V/3A and PI2AES its 24V Meanwell power supply, testing with my binaural microphones, by hearing it does sounds cleaner than 24V W2 jumper on, can see less spikes on the recording.

    Even though sound spacious, bass is not as present when using a LPS, and it sounds bit brighter, but depth is not as good as on a LPS.

    Meanwell 24V < Separate PSU ifi Power X + 24V meanwell < LPS 5V mod.

    Roon stopped detecting the endpoint from volumio. It is a hassle.

    I won't use the 5V mod any more, but still pretty hard to decide, iFi Power Elite aren't a LPS, aren't cheap or available enough to give it a try and there's very few reviews actually testing those PSU.

    I guess by the time, going back to W2 jumper on and Meanwell PSU.

    What do you mean by this? Are you recording the output and looking at the waveform?

    I'm still waiting for my power supply to arrive, I found a power brick that's 36v/2a with a 2.5 stock barrel. More power isn't an issue right, only under powering the unit will be?

    Also, if this works, what do I power the pi4 board with? just anything? they both need to be powered right. Sorry, I didn't read the manual yet. Kind of sick right now and my head feels like a balloon.

    You don’t need a separate power supply to power the pi.

    the stock meanswell psu at 24/1.67 is enough to power both pi2aes and the pi

    you have the option to remove the jumper if you want to power the pi2aes (24v) and the pi separately (5v3a)

    We have enabled ordering for the next batch of 200 PI2AES. Current ship date is Feb. 15th. We will adjust that as the units are ordered to provide 30 units every two week. This should be a better match to the actual delivery capability of our assembly house.

    I dont have the stock power supply, I was just going to buy an upgraded one from the get go. However, I didn't realize it's going to take a month for it to arrive or possibly longer.

    So the only thing I have right now is one that's 36v/2a, that should work without causing issues?

    Question - if the pi and the hat are being powered separately, and I want to upgrade the PSU - is it more important to upgrade the pi one or the hat one.. Which device has more impact on the cumulative electrical noise?

    Think the general consensus is to upgrade the psu for the pi2aes. I guess if you really want to upgrade the psu for the pi, maybe get the affordable ones like the allo or ifi ipower switching power supply.

    I use a lps at 24v2a to power both pi2aes and the pi with the jumper on.

    i recall Michael mentioned as long as it does not go over 48v it would be fine. Guess Michael can chime in on this

    Due to chip availability issues we had to use a lower voltage part. Thus the max input is 40V, though we recommend to keep it to 36V or lower. The new chip has a 40V max input limit.

    I'm about to power it up if it burns this is your fault, JK XD

    I dont know what's going on but it's not flashing the volumio onto the card. When I click flash it says allow command prompt to make changes to your device, I agree then error pops up. Says error occurred when writing check if the file is corrupted. What do i do now?

    Redownload, and try flashing using another utility (if you're using etcher use the Raspberry flasher and vice versa)

    NVM fixed it. had to enable the pi

    Alright now everything works, thanks Mega. Downloaded the plugin for roon, I am using my tablet to connect to roon however the device is not showing up to stream roon from the device, only my roon core and my tablet are the available devices. Radio works, i2s is working, but that is direct from volumio web browser

    How do I get the pi to show up as a device?

    Edit: I didn't read your message close enough, Metro's answer is better. I'd also double check the plug-in is activated in Volumio.

    Volumio has a Roon plug-in that you need to install.

    In Roon, did you open Settings => Devices and does it list your Pi? You need to enable it.

    Yes Gentleman, thanks @Metro and @loadexfa I did state I fixed the problem and nevermind. Also want to thank everyone for helping, greatly appreciated. This is like the ultimate customer support and community!

    But if you click on Audio it shows all the outputs I guess on the roon core or maybe any device if you are on roon app go to Audio and enable it for it show up. Working great now. Cant wait until my linear power supply shows up, this is supposed to sound even better o.o

    Just out of curiosity, does anyone offer the service of putting this unit together for people?

    Also, is it cool to leave this unit on 24/7 or should it be shutdown?

    Hi, All,
    I'm new to this forum and recently obtained a Pi2AES with RPi 4 loaded with moOde. It also has a 7" touch-panel display. I'm a real newby and have a few questions. Maybe there are earlier posts that answer them:
    1) Is the touch feature of the display enabled, or can it be enabled with the Pi2AES?
    2) How do I get the moOde window(s) to show on the display?
    3) I do not have the RPi password: is that something I can get?

    I noticed on an earlier post that the bottom standoffs under the RPi board was loose: on my kit, the M2.5 mounting screws are too long (6mm instead of 5mm) so they bottom out in the standoffs. I think 5mm screws will work.

    Also, the display-case instructions say to use 6-32 screws to mount the display but the display requires 3mm screws. The display screws should be 3.5mm (or so) long so they do not contact the back of the display.

    Thank you in advance for your help!

    FWIW, I leave mine on, unless I'm performing a software update. Barring some sort of power outage, mine will often run 60+ days without being reset.

    If you do shutdown, then make sure you shut down in the software prior to removing power. Otherwise you might corrupt the sd card
