Hi Stee, I can not comment on any of the circuitry, since I am no expert.
But one thing I know for sure, Transformer is "not" a wire with gain...
Transformer might be a lots of wire mostly, but it does not behave like wire with gain.
Google core saturation and hysteresis...you will see things can get pretty compicated with transformers.

You're right. Transformers are TWO wires with gain. 😀

You need a DAC with balanced output
two little transformer like 50VA
and use secondary as primary (raise 1to 20)
and then two amplifier with gain ONE
(mine is a car amplifier sony XM4040)
volume is on your desk by USB😱
I thought this might have something to do with listening to hifi outside and in the nude...
see, folks, here is when we get to the point of that transformer Stee is suggesting
he says like 50watts...I hope he does not mean normal power transformer for mains...just in oposite direction, as step up...because those have pathetic fr response, far from "natural"
that's where I disagree with wire with gain notion...

I also think so
but the transformer with a human relationship 1:10 or less (now i'm using 1:2)
This gives the sound that only vinyl can give
the center image
probably because it acts as an analog interpolator
and is able to reconstruct the acoustic scene
also electrically isolates the circuits
that for balanced systems (raised floor)
is essential
should try to think again

Consider using a transformer designed for audio?
And your amplifier is on the OUTPUT of a power amp?
Not sure what ur trying to tell us...
Or the amplifier is on the input of a power amp?
Are you then bridging two power amps to drive a speaker??
Or driving the power amp differentially?
One might consider also starting out with a high quality amplifier in the first place...
But for budget/inexpensive ways to make things sound "nice" putting a slightly warm sounding xfmr at the input has been found to be pleasing to listen to... nothing new there.

as a matter of fact, using transformer as step up with just buffer after was discussed many times before, nothing new...
but using 50 watts power transformer backwards with questionable amplifier afterwards resulting in muffled distorted sound must be something new, naturally...

do not sound academy
I start from the consideration that an amplifier
increases the tension on average 10 times
and the current 1000 times
is good practice to separate the tasks
an amplifier can be attributed to the current gain
simply reducing the voltage gain - say 3dB
This allows the correction of feedback to be extremely accurate
and will remove any impression of the devices used
This becomes an innovative
if we assign the task of raising the voltage to the signal transformer - say 6dB
which unlike the active devices,
does not imprint any emphasis to the signal source
very linear at low powers
even better
if to compensate for differences between the two half-waves in AB Class (PNP-NPN)
add a second in-bridge amplifier
to ensure that each device works simultaneously with its complementary
in exactly the same point on each curve (balanced architecture)
My call is physically experience before they evaluate on paper
we will have a total of 30W per channel
with a result that I achieved the best ever 😉

Transformers are NOT linear at low signals.
An externally hosted image should be here but it was not working when we last tested it.

just like wire with gain...😀

And who's making quality audio transformers with IRON cores?
*sigh*
