[QUOTE="gavinbirss, post: 1004988, member: 60"] [member=23175]audiounphile[/member] I believe the Allo units, especially the ones that re-clock have the ability to elevate the RPi capabilities even further. The I2S from a Odroid C2 or other SBC's may also be slightly better than the Raspberry Pi if you have no re-clocker. The software support however is lagging a little however. A real-time Linux kernel may also have a slight increase in performance and the network on USB bus of the previous gen Raspberry Pi's actually had a isolation benefit. So if not I2S transformer coupling may also increase performance especially with SPDIF connectivity. Clean power also when possible can also help. I have had great results with a Kali and the TDA1543T (below EBAY board) run at 8V with a Raspberry Pi / zero W. The clock generator on the Raspberry Pi is said not to be accurate enough to produce good 44.1Khz playback. The below item was actually the heart of the Border Patrol SE DAC prototype with a CM6631A USB chipset for coax input.
