Aha, ok, yes, that's a valid point!

I've actually gotten pretty good measurements with my Asus Xonar U7. I could post some measurements here if you're interested.

You could also do what I did: convince your employer that it's a good idea to buy an Audio Precision APx555, then shamelessly use it for your personal projects on nights and weekends...

Do I understand correctly your employer is TI? I would expect there are a few APs in that company :-)

We have a lot of them here at the facility in Tucson, and even more in Dallas. But when we were developing the OPA1622 I made a convincing argument that the SYS-2722s that we had weren't good enough, and we needed the 555

Of course that AP has paid for itself many times over now, and was a great investment for the business.
