Good, inexpensive, A to D Converter?

[Apesbrain]

I'm after analogue input and digital output via AES or Coax which, unless I'm mistaken, doesn't seem to be supported with this unit.

If you're still looking, the Focusrite Clarett 4Pre USB at $650 has analog input via XLR/TS as well as S/PDIF coax output on the rear.

Edit: Just found Tascam UH-7000 which would seem to be an option?

It seems that @Blumlein 88 has a similar interface and may be able to give some advices. I only saw some measurements on the DAC part.

I have a Focusrite Scarlett 18i20. It likely is very similar in performance if not identical to the 6i6. I can answer some questions you have as well as provide some test results of it as AD or DA converter.

I am not the OP (who wants to buy an ADC right now), but interested to see if your measurements are similar to their specs.

The 18i20 you show was a 2nd generation, and mine is 1st gen. They lowered maximum gain in the 2nd gen which altered the specs a little bit. Mine gets within 3 db or so on A wtd noise of the spec which is I think 4 db worse than the spec in your link. It is almost dead on the THD spec. Dynamic range is again off by 3 db or so. Basically from what I've seen Focusrite is honest on their specs or quite close. Nothing way off I've seen from their gear.

So their specs are the best you'll get, they don't seem to over-perform claims. And these kinds of things are usually optimized for a particular signal and gain setting. So if you are not using the optimum of all those factors you'll end up a little less good than the noise specs. But close, reasonably close.

If the purpose is to digitize vinyls or old cassettes, wouldn't any ADC could do as the SNR of the source will be less than 60dB? Like this one :
a cheap one@35$?
The only question is which output type and reliability...
