[sdiy] CoolAudio? USB audio streaming/codec test question

I recently designed a PCB using the ADAU-1701 and had it built at JLCPCB which worked out much cheaper than manufacturer evaluation boards.  (Shouldn't really say that as we design quite a few of them :-)

All the ADAU devices are pretty similar in performance.

Subject: [sdiy] CoolAudio? USB audio streaming/codec test question

Hi guys,
I am tasked with checking out an Analog Devices codec (ADAU-1772) and want to interface to the digital audio IO.
I see MiniDSP has a USB Audio Streaming kit thing that may be able to do it and CoolAudio has a TCD3020 but they seem gone (what happened?).
How do you guys go about validating a codec other than just using the eval board Analog Devices sells?
