Look up. The header image shows an iPad feeding a Peachtree nova300 integrated amplifier’s in-built DAC over USB but as a Roon Endpoint. I’m not using the Peachtree all-in-one’s DyNEC Type A USB input. This setup sounds a little better than the Raspberry Pi Roon Endpoint-setup/s introduced last week. How did we get here?

The iPad is connected to the Peachtree’s Type B USB input with a combination of Apple’s Lightning-USB adaptor (US$29) and an AudioQuest Carbon USB cable. And that’s it for hardware here.… Read the full article
