Cool! The TPA3116 is a nice sounding chip don’t you think?

  Not really - specs and sound wise, it's not any different from any other integrated class D analog input amp. Pretty run of the mill THD and SNR specs. It also has one hell of a startup transient. It was not a fun exercise to get that passing startup click/pop requirements. I said some words about TI in anger while bench testing.

    Interesting! Thank you! Any chips you’re particular to?, or are otherwise interesting?

      Analog Devices is making some neat digital amp chips that have an I2S digital feedback path from the chip to the digital source (processor or similar). The idea is that you can use this to digitally correct for imperfections in the transducer. Never used them in depth, but the demo they showed us on an EVK was neat. You can trivially pick up 6dB improvements in SNR, or more with tuning and characterization. My beef is really more centered on the fact that, if you're already at -100db of SNR, what's the point?
