Just so that there is no misunderstanding...

The Streamer is a fully built, ready to go plug and play device. There is no assembly or configuration required.

If you want a cheaper solution you can buy the kit and assemble yourself.

I have had multiple questions regarding volume control on the unit.

The volume control can be either through the knob on the unit or through software when you control the device remotely.

The HW volume control on the unit (knob) will be better than to the SW one. Both will sound great.

First review / writeup on the PecanPi:
https://audiophilestyle.com/forums/topic/55945-orchard-audio-applepi-and-pecanpi-raspberrypi-dacs/

Some quotes from the writeup:
"I know very well how the SBT and AudioEngine 5+ powered speakers sound, but even as I was being somewhat distracted by enabling this new RPi endpoint in Roon, my focus was immediately drawn to the music when I started up Jean Michel Jarre’s latest “Equinoxe Infinity” (via Tidal). It’s a new reference recording, and I immediately noticed a significant sound quality improvement. Granted the SBT is probably a better streamer than DAC, but holy cow! The stereo imaging on Flying Totems (Movement 2) was outstanding, and the bass much, much tighter. Everything was just better."

"Thebass is huge and the imaging is precise. Way better than Ithought possible. I even forgot about wanting to add a subwoofer. My wife even commented on how great it sounded and wants me to now set up something at her office. What just happened?!?"

I'm quite interested in the PecanPi Streamer...   I'd been a long-time Squeezebox user since back in the early days of SlimDevices.   When Roon started supporting Squeezeboxes as endpoints was when I jumped from using LMS to Roon (damn, over 3 years ago now) and still have several Squeezeboxen in use at home as Roon endpoints.   This PecanPi Streamer sounds like a great step-up at a reasonable price.   While taking the kit route sounds interesting, the preorder pricing seems like a great deal.   Hmmm....

Mike, Leo did a demo of his Apple Pi DAC mounted on a Raspberry Pi computer and it sounded quite good. It even got a thumbs up from one of our most die hard analog lovers. Since this Pecan Pi steamer should be and improvement over hsi first generation products I would think it will sound very fine indeed and would be a worthy upgrade to Squeezebox.

You are correct that is what I demoed, the PecanPi is the same analog circuitry with noise and jitter improvements.

Hello, Leo.

Your PecanPi streamer looks interesting. Is it shipping or still in pre-order status?

Is it wifi or Bluetooth capable?
