Input/Output line level transformers for digital glare


I have been told that putting "iron" in the line output from the preamp to amp makes for a wonderfull change in digital glare issues on a digital media system

How do you do this? With single ended ended rca analog input/ output?

it supposedly does not affect frequency range nor dynamics?

My "test " is a Rush song called " Red Barschetta" that I found great on a lp in the treble & cymbals, but streaming or cd, nope!
It may not be the fault of the digital gear that this sounds bad. It might just be a poor transfer. If other recordings sound OK (against the LP in particular) then I would not use this as a reference.
Guys:

I have Amarra and have Dirac room correction, so covered the tone down the Jim Thiel "Thiels"
The Red Barshetta note is true on source quality!!!!!   Big differences especially since going to Tidal and hearing differences

Other Nasty recordings in the " screaming edge" frequencies that my stupid hearing magnifies are:  Foo Fighters The Pretender & Bob Dylan Like a rolling stone & CCR Commotion

Ive heard the music on lots of systems and compared some to the vinyl ( great turntables(
vinyl is always, always clear and clean with no " fuzzy hiss" that I hear
stupid hearing and it's accents

The only exception is. Full Bricasti system with Tidal speakers;  So far

I must be doomed, until I give up on Digital or run across $100k fun money
