Interesting, I didn't see that topic. Most modern DACs have low enough output impedance to work with Cosmos ADC directly, however, old...

It is not really a problem, just a cheaper one ES9039Q2M has 10x times lower H3 of 10kHz. I have doubts if AK4493 H3@10k would be lower...

GSM no problem, but LTE, especially 4-6G.

I never said the DAC was designed for measurements, but if stupid bloggers say so, we can understand. Bloggers need something to say...

All my DACs use Ti/AD opams only.

Hmm, but why isn't optical output? Don't you need an isolation?

ahh, spdif is RIAA but USB is stereo? This is not a documented mode at all, I see nothing in the 9822.odf about it.

I didn't change the stereo/mono modes in v14_SPDIF firmware, but just now retested that anyway and found no problem. Did you read about...

you'll overload the ADC chip by DC, that's it.

rather up to 380k.

and at 768k!

I use only one and free Darktable 5.4 - an extremely autistic/geeky GUI, but the tone&color is unbeatable.

What kinda SPDIF-board did you buy? Usually, such boards have I2S input. With Cosmos ADCiso you do need only the optical output(Toslink)...

ok, try that:
