What would happen if you fire a pink noise and use a real time analyzer instead of single sine waves and a decibilimeter?
If you do not want pink noise, then imagine two setups playing the same classical music track:
- Tubes directly coupled to electrostatic transducers; and
- Tubes to transformers and then transformers to electrostatic transducers.
Then imagine two microphones and two graphic equalizers, each one coupled to the transducers of each setup.
Now imagine dynamic charts displayed by the graphic equalizers 1 and 2. Do you think the the bars representing higher frequencies would peak at the same db level in both graphic equilizers?
My intuition says your question has something to do with saturation in transformers.
I was trying to understand the relationship between core materials, sizes and geometries (including lamination), the calculation of wire wounds, the wire gauges and the induced magnetic fields at different AC current frequencies. Furthermore, when the whole audio spectrum is being played, as in music, I was trying to relate all that building parameters with saturation and how such saturation changes the impedance in higher frequencies. But I confess I got lost.
Now curiosity is back and I will try to read more about it.
