This is what you get for $2K from Metric Halo: ULN-2
It really does a lot more. However seeing the price for a premium box for audiophiles established I may want to get one going. Audiophiles pay more and never look at specs, so flowery claims really make a difference.
The ARDA chip makes some broad claims but their specs are not a lot better that the AKM (or the TI).

Notice that just about ever spec is 'A' weighted.
It's not bad but seems average for today.
That box for that particular model (the ULN-2) is a standard design. There's absolutely nothing special about the box. You can get a faceplate made for not much money either. The connectors are standard pro stuff. It has maybe two circuit boards in it, tops. Total cost for the actual parts is maybe a few hundred dollars at best. I doubt they invented anything (and thus have no patents on the design), so the design could not have cost very much. To me, it's a total ripoff. So, thank God for people like Davada who are willing to design something incredibly good for not a ton of money.
Very average today... many in the same range. What ever happened to the 24bits = 144dB dynamic range story? Where are the missing dB's? Where did they go?

Has anybody here experience with the AD7760?
Its specs are not a-weighted but absolute, sth. I would really prefer
for measurement purposes. Essentially removing everything below 1KHz
from the noise numbers seems kinda unfair. If there is 1/f I would like to see it.

Wasn't there an app note for the BB ADS1210 with the title
"How to get 20 bits from your 24 bit ADC" or sth. like that?
