    Hadn't seen this shared yet, so wanted to share this recent review of the Pi2AES on YouTube:

    .

    This reviewer is awesome, and has reviewed other streaming products on his channel before. I have really enjoyed his reviews thus far, and he focuses much more on the sound and how it compares than many other audio-focused channels (i.e., marketing channels). The Pi2AES compared favorably to the Allo DigiOne, SMSL SD-9, and the Bluesound Node 2i. Congrats Michael and team!

    Or does it? The first item in the "About this item" description says:
    • Input Volt Range: 100-240V (Worldwide Compliant) Output: 29.5V 2A

    wait, what? It says in the description "Input Volt Range: 100-240V"
    upd. oh I see, saw your screenshot. I'll clarify with the seller.

    I am waiting for my pi2aes and just want to clarify something:

    I currently have Volumio on Pi going to a usb dac. And in the Volumio settings I have I2S set to no, and I picked my USB dac in the dropdown. OK.

    My pi2aes will be connected to that same DAC via SPDIF digital cable. In which case do I need to select i2S = yes, and pick Allo Digione as the DAC? Or what?

    Thanks

    Correct. You can also choose the Hifiberry Digi + Pro.

    I have asked volumio to add our board to the list, but they say because we do not have an id eeprom it does not conform to the hat standard. No biggie.

    Hi, Michael!
    I have just bought a Pi2AES this weekend, so I'm waiting mine.
    Could I feed it with a LPS 19v or an iFi ipower 12v PSU? I'm planning to keep my Pi4 on the 5v LPS through the USB port.
    Best regards from Brazil!

    Hey Brazil, I think it needs 24v min

    The PI2AES is optimized for 24V, but can take 19V to 48V.

    mega thanks to @GoldenOne for the great write up on the 5V mod.
    a newly delivered iFi PowerX 5V is working great and do believe there are some clarity improvements overall going SPDIF + AES into Yggdrasil A2.

    This also means good news for other pi2AES owners:

    1. I have a bunch of the barrel adapters and jumper wires necessary to do this mod.
    if anyone in CONUS wants 1 barrel adapter + 3 jumper wires (1 wire in case of failure) for a small PayPal donation, i can mail out in a plain envelope I think.

    2. anyone want a Meanwell power supply for their pi2AES, send me a private conversation message.
    very cheap + USPS shipping ?

    Something worth noting about the power mod, Michael Kelly posted on the goldensound link that it bypasses the protection circuitry so you risk damaging your Pi2AES and the Pi if there are "any voltage spikes, ESD, etc". I'm going to try anyways, worst case I get to give Michael more money. :D

    Thanks for your reply, Michael!

    It's an awesome device.

    As soon as the Pi2AES arrives here, I will give my 19v LPS a try and I will let you know. I just can't wait!

    Best regards.

    So I understand that when restarting the Pi2AES, doing a hard restart by unplugging and plugging it back in risks corrupting the SD card. This is what I've always done but I'd like to switch to doing it online. But I can't setup a static IP address for the Pi2AES so does this mean the IP will be constatntly changing and I can't just bookmark the page for the specific Pi2AES to go to the moose page easily to restart it? If I could do this, it would actually be easier than reaching around and unplugging my Pi2AES and it would mean I could add a NoiseNuke to my speakers Pi2AES too because I could restart it online and wouldn't need to use a remote A/C on off switch to restart it which makes the NoiseNuke impossible because it has a power on/off sequence.

    I guess I can just check FING every time but it's kind of a pain in the ass. Would be nice to just have a bookmark for each of my Pi2AES to go to the moose page to reset them safely and easily.

    You can set a fixed IP in the DHCP setup of your router. You should use something high like 192.168.0.240 or so. Then insure your router does not provide auto-IP addresses above 240. You will need to be able to recognize the MAC address of the PI (this has nothing to do with the PI2AES BTW). You could unplug all of them but one, then see what shows up in the router DHCP table, then add the others one at a time and assign IP addresses accordingly.

    Since this is not actually a PI2AES issue it may be better to ask this elsewhere. :)

    FWIW, my pi2aes at work is dynamic IP and I think the IP address has changed once in about 9 months (and that was after a power outage that took everything down for a long weekend). In general, I think it will be assigned the same IP address unless it is off and something else grabs the IP. For an almost always on device, the risk of change is probably pretty low.

    I'd make the bookmark and see how often your IP gets reassigned... I'll bet that its pretty infrequently

    I don’t know how to setup a fixed IP everyone here and is internet tech challenged. I guess I’ll use FING every time.

    it’s definitely Pi2AES related because it’s about how to restart the Pi2AES which it sometimes needs very frequently.

    oh I just saw @dasman66 reply. Cool. I will now hookup a NoiseNuke to my speakers Pi2AES! Very exciting.

    What OS are you using @rhythmdevils? Depending on build, most have a .local URL. eg. https://moode.local, or https://ropiee.local. However, that only works on computers and not portable devices like Android phones or iPhones.

    But, you can use that .local, go to the info section and find the IP of the device, then you should be good.

    Also, if you need help setting a static IP for your Pi in your router, just hit me up. I have screen sharing tools and can walk you through it.

    Hoping that this is the right thread for my question:

    I am going to try out the somewhat esoteric Symphonic mpd (smpd) RPi4 audio player. For installation it is asked whether the hat, in this case Pi2AES, should work in slave or master mode. As the Pi2AES has its own oscillators, I guess I should choose the master mode option. Is this correct?

    Also: are master mode and non-PLL mode synonymous?

    The IP address definitely shouldn’t change often and you can usually access it via http://moode.local or http://volumio.local or whatever. The fly in the ointment is Android not supporting zeroconf but maybe they’ve finally added support since last time this came up. Edit: what Azimuth said except iOS has always supported zeroconf.
