Transformer Type vs Sound

[dreamer]

Hello,

Anyone try to use the same power, same voltage but
different type of transformer to power up the same
circuit?

I trired the followings:
Toroid - build from Z9/M4-0.3mm core
seem that the sound become clear......but listen to it
for longer time, feel that somthing is missing.
abit week in bass/mid-bass region.

R-core - build from Z9/M4-0.3mm core
close to the performance of Toroid but more powerful.

EI-core - build from Z11-0.35mm core
Feeling much more powerful, strong in bass,
good in human voice, good sound stage.

Nearly the same result when I try to insert a isolate transformer
between the power line and the amplifier.

Anyone try to do this test too?
hope that someone can share their experiences.

Thank's!

There seem to be more factors at play than merely the core type. Per example I have experienced widely different sound between identically sized EI types. Still, i agree with some of your observations.
