Can I have provide an SD which has not had the first boot on it yet?

Post # 2 updated with test data.
PecanPi DAC – 224.99 – 25% off
PecanPi Streamer – 399.99 – 20% off
The streamer is fully assembled and ready to go.
With every preorder you will be entered into a raffle to receive our next product for free. It will be a 100W Class-D amplifier.
Will be shipping in 3 to 6 months.
Looking forward to try. One thing is not clear to me: The optional Roon end point. Is that the license or some hardware adjustments? What’s the $100,- for?
I imagine the Roon endpoint using the RAAT SDK as opposed to Roon Bridge which is not licensed to be redistributable. Much like the Metrum Ambre? I
Roon is much more work to setup, so the charge is for additional labor involved not for software or hardware.
How so? Are you using the RAAT SDK?
Hm. Then this is a no-go for me.
that’s getting rather expensive for me, and when you add the case and volume not going to happen…nevermind the 3-6 month wait time
If you buy case, volume control is included.
At $350 for DAC plus case you are getting performance that would otherwise cost 1000+.
For the Rpi at an SNR of 130dB and a dynamic range of 125dB the PecanPi delivers the lowest noise and highest dynamic range of any I2S DAC.
Assembly instructions are coming. It will be very simple just two screwdrivers needed, phillips and flathead.
No cutting wires, no soldering.
I can appreciate the tech but I need to spend that much on repairing my r2r dac at this time. I’m sure there will be those here who do want the PecanPi. Maybe I might later too.
Can Roon Bridge not just be installed by the end user on, say, Volumio using the normal process for an RPi, or am I missing the point here?
It can be as far as I know, but you need to have the technical know how of how to do it.
And if you are able to this this on your own you can save 100 bucks.
Ah, fair enough, thanks for clarifying
Might be nice if you listed the formats supported and maximum rates. Assuming this is a dual mono dac implementation. What chipset is it using?
- Supported sample rates: 44.1, 48, 88.2, 96, 176.4 and 192kHz
- Supported bit rates: 16 and 24 bit
It uses dual PCM1794A in mono mode.
It’s going to be interesting to see how it stacks up against the Allo Boss 1.2 running at 384 kHz/32bit. Or the Katana: 384 kHz/32bit ESS SABRE 9038 DAC chip
With Support for DSD64 & DSD128 files through DoP (176.4k & 352.8k PCM frame).
Katana has THD+N of -109dB and dynamic range of 115dB measurements are posted here:
Allo Boss has much worse measurements:
Come on this is ridiculous. Setting up WiFi for 50 USD, wow that must truly be complicated…
Seems like everybody wants a slice of the audiophile cake.
Sort of Roon customers have money, so installing a Roon image is 1000 times the price of installing a rune image. Good luck with that.
