PI2AES Transport - I2S Output

Audio Components Transports
#1

Hello all! I decided to start this thread since several of our customers (I own Pi 2 Design) have been using our PI2AES Raspberry PI Add-On to interface with a number of PS Audio DAC’s. Reported results have been very positive. If anyone has questions about the product it can be found on our web site, www.pi2design.com, or emailing us at support@pi2design.com. I will also be monitoring this thread should anyone have technical questions.

I apologize in advance if this is seen as a naked sales attempt. While we would certainly love more sales, I wanted to make sure we understood and could answer concerns PS Audio users may have about our product. :grinning:

Cheers,
Michael

Welcome, Michael

At least two of us use pi with the hifi berry digi plus pro, spdif and optical, can you comment on the advantages of using this board instead of that one (apart from the obvious point of having a proper aes port)?
Thanks :slight_smile:

Obviously the AES Coax (BNC), AES balanced, I2S parallel and I2S over HDMI offer significant functional advantages. Using the same interface however, the differences are a bit more subtle. Use of better voltage regulators and lower jitter clocks make a big difference in overall jitter.

We have plots on our website that show the jitter of our board compared to the allo Digione signature:

Last but not least, the ability to power the raspberry pi with clean 5V@ 4A, and our board from a single low-cost power supply, while still achieving outstanding performance, is another plus.

Regards,
Michael

I assume it accepts an ethernet input from a music server? What is the status of Roon readiness?

Another couple of questions:

  • I’d be using it with Logitech Media Server (on a NAS) and run PiCorePlayer with SqueezeLite using the analogue video out, again, any idea if this is a supported combination (i.e. PiCorePlayer sees the digital outputs ok)?

  • Acrylic cases are cool an’ all, I love 'em, but I am currently using a steel case for the Pi/HiFiBerry combo, thinking shielding was more valuable than the cool see-through cases. Any thoughts on this?
    Should I get one and wrap it in tin-foil?
    (and no, I don’t have a tin-foil hat :wink: ) It’s just always been sound engineering practice in my world…

Thanks again!

Oh yes, and, international shipping? (UK, for example) :slight_smile:

#8

The Raspberry PI support ROON by using the ropieee distribution. This then presents a ROON compatible endpoint.

International shipping via USPS First Class International is about $25 USD and takes 1-2 weeks depending upon customs. Please note that right now we are back ordered and it takes us 2-3 weeks to get a new unit out the door. We hope to dramatically shorten that, and even actually keep it in stock!

Well tin foil is an option, but the you can’t see all the LED lights! As for PiCore player it is supported and we have tested it. Note that all of the outputs are active at the same time. No selecting required.
