I’m from Buenos Aires/Argentina.
I have a really simple setup, I had some trouble (I’ll post where it belongs later),
it’s a Raspberry Pi 3B,
with a Xmos2 (DIYINHK USB 2 I2S) and a SABRE ESS9023.
I have a LM4780, with some good components, and a separated dual mono regulated powersupply.
And a Klipsch RF62-II (I think that was the name).
