Do you believe Studer made its own? That would be uncommon for what primarily was a tape machine manufacturer.
Anyway, would be interesting to find out who made the transformers. There are never enough good ones out here!

If a manufacturer is able to make recorders like the C37, A62, A80 mixing consoles like the 900 series they are certainly able to produce input transformers.
Yes Studer made their own audio transformers.
Polygram ordered large quantities for the mixing consoles that were designed and build in  Baarn, the Netherlands.
Studer and Polygram are history, no more excellent analogue equipment from these companies.
btw Studer also manufactured their own recording and playback heads.

For a designer small transformers that do not transfer power are easy to design.
Sonic quality depends largely on the sort of metal used for the core.

Designing output transformers for tube amplifuers is a different piece of cake.
Minimum distortion at low frequencies and a large bandwith like 150 Khz are not easy to combine with power transfer.
Partridge in the UK and Unitran in the Netherlands made those.
Famous American tube amps like MacIntosh and Harman Kardon were based on superior output transformers.

Input transformers are not rocket science with all due respect for Haufe.
By far the best input transformers I ever got my hands on were made by Studer.
Not exactly rocket science, although I wouldn't be astonished if some made it into the Sojus rockets  :)
Building a good sounding audio transformer is high science.
It's even harder if you want to combine the extremes in ratio, bandwidth and level/distortion.

It's no wonder that well made, maybe like your mentioned Studer's or the famous Neumann BV8, are so sought-after.

No idea what you mean with high science.
The guy who time and time again astonished companies with their own scientific labs designing transformers they could not develop let alone produce was what Germans call a Diplomingenieur.
He was not educated at university. I am referring to Mr. Y Drost at Unitran in Weesp, the Netherlands. He was my supervisor during the time I was there as part of my study.

He could predict with maximum 5% tolerance what the results of a new design would be meaning, banwith, distortion etc.
A pity this knowledge was lost when Unitran closed in the eighties.
