Care to guess what it uses for its guts? A Raspberry Pi. Case in point the OktoResearch dac 8 Stereo is a critically acclaimed streamer. So as I said, I'm not blessed with super hearing nor the seemingly limitless pocketbook to chase audio nirvana where every purchase let's me hear stuff in the recording that I've never heard before (I always wondered if after enough upgrades does the song still sound the same with all those new things people discover in it? does it still provoke the same emotions?) BUT from a pragmatic point the law of diminishing returns kicks in and one really needs to check their sanity about what they can actually hear. And for graph peekers the intermodulation distortion + noise with swept frequencies had the Raspberry Pi's USB at up to 4x as good measuring as the HAT. Both of the USB connections edged out the Toslink and Coax Raspberry Pi HAT's measurements (granted it was by 0.00003). Per the link below a USB connection from a Raspberry Pi 3B USB was exactly the same as from a regular computer in regards to THD. Out of curiosity I did some quick research. If there is any noisy signals to be had the closer the conversion takes place to the SOC/USB and ethernet controllers/power runs would, by necessity, be worst than those further away, no? So a HAT which is mounted a cm (?) away from the source of the noise would be worst than a USB dongle performing the same function that's 10 cm away wouldn't it? After all on a SPDIF connection the dongle is going to be converting the USB signal into a PCM signal unlike a DAC which would be converting the digital signal into an analouge signal. ![]() I won't claim to have golden ears so I am not sure where the "usb is noisy" comes into play.
