    Hi,


    I am a newbie in this forum. Early this year I was looking to build myself a music streamer and so had decided to sell my SotM SMS-200 Ultra Neo. Am glad that I did as the RPI4B + Pi2AES performs really well beyond my expectation. The Pi2AES complements the RPI4B to a level on par with the SotM at fraction of the cost.


    Just like to share a YouTube video on the self-assembled music streamer made of aluminium chassis housing the RPI4B + Pi2AES + Sigma 11 LPS (5V + 24V) + 7.9" Waveshare Touchscreen + Teac CD drive.

    Hope you will enjoy.

    This doesn’t have the ability to not power the pi like older versions?

    Fwiw the official Pi power supply isn’t 5v anymore it’s slightly higher.

    @Soul Analog

    Congratulations! Fantastic job.

    It is good to see how to build a DIY project around the Pi2AES. The Sigma 11 LPS is a good match for this project also.

    I really expect that after the components shortage we are experiencing that the Pi2AES return to production.

    Best Regards,

    The problem I had is that the 5V input is directly used on some of the AES driver circuits. Anything over 5.3 or 5.4 could potentially damage those parts. It is clearly an engineering failure on my part to not understand this issue more clearly. All my previous designs either had a switching circuit between the input and the 5V rail or took the 5V down to 3.3 and did not use the 5V directly.

    Actually we had our 502DAC that allowed external 5Vinput. We had no complaints about it, but I suspect that was because the raspberry pi 3 was much more forgiving of a small voltage drop than the 4.

    Hi,

    Thanks for the interest. Please let me first tidy up the connection and cabling inside the chassis. Will share the details inside once it's finished.

    I couldn't agree with you more. I was using a SMPS before that and once the Sigma LPS was up and running, the soundstage became livelier and more engaging. Couldn't be happier with the improvement.

    There is an updated HW Reference Manual for PI2AES-LITE on our website. It also includes case assembly instructions. Every PI2AES-LITE comes with this case.

    All PI2AES-LITE back orders have now shipped. We have a handful in stock and will continue to build that stock up over the next couple of weeks. Typical leadtime will now be 1 to 2 business days after receipt of order.

    It sure has been a long time since I’ve been able to say that!

    Hi SBAF Brains Trust

    In anticipation on the delivery of my Mercury V2.
    Do you think I would need a LPS? And if so, what's a bang for buck unit for about under US$200
    In am in Australia and have a 220-240 V and 50 Hz power supply here
    Asking now as it will probably have to come from overseas as well OR do I even need a LPS?

    Cheers and Beers

    Do you absolutely need LPS then NO
    is it good to have LPS with Mercury then YES as it is designed to perform or scale well with LPS.
    Now will you notice a difference will depend on the gears you have and the LPS you get
    My suggestion would be to start with default power supply and get LPS later

    Would this, or another AES>BNC adapter, have any affect on the SQ of a gungnir going into the Pi2AES over just using BNC?

    Thanks for the reply. Yes it's a solid idea to try and see it first

    Don't have a Pi2AES yet, but it's on my list. Just had another quick question—how, if it's possible (read somewhere this was recently implemented?) is parametric EQ applied in Volumio?
