[*]Headphone output power into 32 ohms: 390mW
[*]Headphone output power into 16 ohms: 780mW
Hello from France,
I don't understand the Headphone output power ....
Just XLR and RCA apparently

Sincerely yours

The RCA outputs double as headphone output, you will need an RCA to 3.5mm adapter, see my website.

Assembly will be very simple just two screwdrivers needed, phillips and flathead.
No cutting wires, no soldering.

Instructions and how-to video coming soon.

Streamer does not require any assembly and is ready to go.

Seriously, I've signed up (and paid for) the new Pecan Pi DAC. Does anyone know when (or if) there will really be one delivered? I purchased it based on those glorious graphs which looked suspiciously like those from Audio Science Review. Am I correct about the source of the graphs (or even more hopefully an associated review) and does anyone have any information about when a Pecan Pi might actually materialize out of vaporware?

All preorders will ship in 3 to 6 months.

If I get a lot of preorders then it can potentially be quicker. So please spread the word with your friends and on social media.

So, it's somewhere between June and August? Will there be an earlier review on ASR?

Potentially. I have some other reviewers lined up first with the units I do have. Depends on how long it takes the other reviewers.

The DAC itself does not do any MQA decoding, but if your software handles it upstream it will work. At this time I don't know of any software decoders for the Rpi, maybe somebody else can chime in here.

Any plans on a multichannel version? Say 8ch with options to expand by stacking modules?
