xaudiomanx,
Totally agree on all points. However, even with the same winding ratio and getting to the desired primary and secondary impedance (which audio note does not define), there are many variables that would have to be considered for another pair of transformers to behave with a similar sonic characteristic as built into the AN transformers and their house sound.
There's a lot of art in making transformers of really high quality and especially when dealing with low level audio signals. Various winding techniques, core gapping, core materials to name a few. Some of the AN transformer designs are unique.
Custom amp builders who have had the time to try output transformers from various manufacturers will talk about the different sonic characteristics they have even though they are designed for the same circuit. And unless you were lucky enough to evaluate and compare them, you will be paying for iron that you'll never know for sure is as good as the AN gear designed for that application.
All that said I'm not denying the possibility that you could buy an off the shelf Lundahl or Magnequest and wind of up with even better sound. I remember an AN DAC kit with lundahl OPTs and they liked the results, but unfortunately hadn't heard AN OPTs to know how they compared.
I think Audio Note could survive while charging much lower prices. The unreasonably high prices for their flagship gear is really the biggest gripe I have with the company. OTOH they've been at it for a long time now and their DAC concept has withstood the test of time.
