Yes. And it's the first amp I've ever heard of that can sense and adjust to the A/C voltage input.
Which specific amp(s) are you talking about? As best I can tell none of the ATI or Theta amps will sense AC input and automatically accommodate for 120 or 220 operation, but I could be wrong.

I thought that is what this means from the original post:
" These AT5XXNC series amplifiers break new ground in other ways. They are the first ATI amplifiers to use micro-processor control for turn-on delay and feature automatic AC power recognition and configuration. The amplifiers not only recognize whether they are hooked up to 117V or 230V nominal power, they automatically self-configure. The amplifiers also incorporate a new and novel "sleep" circuit "
I guess I should have read the entire press release. That's pretty unique. Thanks.
That feature is ordinary these days. Typically, more costly to less ordinary in a linear PS.
Agree, it's very common for switch mode power supplies to accommodate a wide range of input voltage and frequency. But the press release says these amps use linear power supplies. I wonder if those might be linear power supplies AFTER the input switch mode power supply as you may have hinted.
If your using class D amp technology, then a focus EMC is already a must. Why not just use SMPS given its inherit advantages when EMC is well designed? Seems like a linear PS at that point may be more about marketing and less about system prrformance.
Agree again. Audiophile mentality, and marketing to audiophiles:- Linear Power Supply Good.
- Switching Power Supply Bad.The real answer is, 'it depends'.
