Yeah...sorry..I guess this qualifies as a rant.
Rant away, you have your rights. But the more you DIY, the more you'll find that many of the parts high end manufacturers use, are just off the shelf. The more expensive they are, the more likely that their products are being controlled by their marketing department, hence the special decal, and of course special trademarks. That transformer you describe is a Talema transformer and most of them are priced between $10 to $30 from Digikey. Even less when you buy in quantity.
The talent though is
not in parts procurement, its in the
development, execution and of course, design.
And as for the The Cornet 2, it's such a special product that it doesn't need the endorsements from anybody but the owner

Of course the $1400 Moon phono preamp has probably $50 in parts and another $100 for the enclosure

. Its just how the high end works. And that transformer is about 10VA, not expensive at all. And what does "Ultra Low Noise" really mean? Ultra Low compared to what objective number?

Think about it.
That being said, their equipment sure does
look cool. No idea how it sounds though.
And Pat...Love your website, very, very humorous to say the least. I bookmarked it right away.
Best,
Anand.
