Let's be honest- it's
marketed to the consumer crowd, it's not pro/commercial by design and some of the popular consumer equipment isn't true complimentary balanced, even though it has XLR connectors. That's important- if it's not, it lacks some of the benefits and it's just giving people what they want.
The fact that people use it doesn't mean it was meant to be used in that way.
These newer models came out after home theater became 'a thing' and are made to be compatible, I'm not referring to this stuff, as good as it is but how many times have you read that people heard his and other noise immediately after adding a 'pro' amp? That's not always removable by making an adjustment (other than switching between two sensitivity settings) and pro gear has a way to do this, usually a rotary potentiometer. These are on power amps, line/distribution amps and other items that aren't usually included in consumer systems.
Two reasons the real pro stuff isn't used in home/consumer systems is price and image. With 'high end' equipment, it's just too industrial-looking and a lot of pro gear is expensive, but part of that is due to the specs it may be required to meet. Years ago, an AH member, who was adamant that his way was the only way (and he left) argued for some capabilities in a thread about power amp specs and he wasn't on the side of "one channel driven @1KHz is just fine"- he wanted everything to keep working while it was failing during events, used for fire alarms. We obviously don't need that, but the life safety industry does. Markets for electronics exist that consumers never see, think/know/hear about and the equipment can be used outside of their intended uses, but it's not always plug n play.
Pro/commercial equipment isn't designed to provide 'pristine audio' with ~zero noise and distortion because it really doesn't need that- it's usually used in applications where people aren't close enough to the speakers for it to be audible. For those applications, different models are chosen and the specs aren't the same as what we see in the consumer world.
