THAT1512 Pre. DIY, reasonable replacement for Cheap Preamp Art?

Just curious why you are bent on transformers; it's been pointed out that they serve little purpose in front an instrumentation amp IC.

To me it's some of the transistors inside the IC that serve little purpose on the back of a balanced input transformer.
It's just what I have now and put together and see how it adds up.

Thanks.
I ordered input Txs, but because of supply shortage, I keep waiting and waiting and waiting for shipping.
So I end up winding my own Tx before the others ever get here.
But it's finicky stuff to do.

Have you made any more progress?
