That's the thing: it is commonly accepted (would you like an industry list?)
It's a red herring, really and you've already acknowledged that AES48 is not commonly accepted in home audio. You describe your MP-1 preamp as "featuring Balanced Differential Design®" and state it's "still one of the very few preamps to support the balanced standard (AES48)." You then go on to insist that only AES48-compliant designs are "proper" balanced designs.
So yes, you're here to promote your products, Ralph, and that's fine. You've earned the trademark and multiple patents and you've earned the right to tout them. But when you insist that you have found The One True Way, and that competing balanced designs aren't "proper," it warrants a reminder that with most things in life, there's almost always more than one way to accomplish a task. And that is certainly true in high-end audio.
