+1. I'm hoping to implement RIAA with my Nadja to compare to an analogue RIAA. Other things to look into first though...

For beta testers: I have here a revision with all what we planned except mix FIR/IIR.

If you can test it, please let me know how it goes, thx!

If you're not beta tester, use this file at your own risk ...

The option to include input processing on the output data is great. When I enabled this option I expected to "see" what I have been measuring. However, the impact of the analog gains is missing (I understand why). I forgot that I increased the overall analog gain while online. I would like to emphasize the need to make the entire gain structure "visible" offline.

I was hoping for the possibility of pairing as "Ryssen" described, is that going to be an option or is the 1/5-2/6-3/7.......the only option planned ?

Why do you need to pair 1 and 2 (and so forth) rather than 1 and 5? Doesn't it make more sense to pair 1 and 5 in order for the processing load to always be perfectly distributed between the cores? After all the only difference is where you plug in your cable.

Urban is right: the selected pairing is the most natural for the device architecture: it helps balancing the load between both cores.
Also, when you're using the onboard DACs, you'd want to keep one quadruple RCA for one speaker and the other quadruple RCA for the other speaker. It kind of makes sense, and the selected pairing is in line with that logic.

When you use your own DACs, then you're free to route the signals at your will to the expansion port (Menu Settings -> Expansion Port 0 routing). In other terms, nothing prevents you from having two paired channels on the same I2S line if this is what you want.
