Default input transformer frequency response?

is the frequency response on their datasheet absolutely relevant? i'm looking for a suitable (cheap) 1:1 transformers to go with my differential tda1543 dac and even ones from hammond and tamura all have rolled off response until you shell out $100+ for their broadcast models

You are right.

Hammond 560 series

$55 at mouser...probably $100 by the time it gets to you.

Active differential an option?
