Dover,
This simply means that the Zesto added the network in order to deal with the transformer behavior. That is very different than having a phono with that network at the input and then designing the transformer to work into it. This is an easily solvable chicken or the egg paradox. My response asking about this was in relation to the quoted exchange below
I took this to mean that the transformers were designed to work into that specific network which made me question where that network actually exists to require that transformer design to naturally work into it.
You said above:
If the time domain is more important than the amplitude domain then what is the logic of using a network on the secondary that corrects for the amplitude domain at the cost of additional phase shift in the time domain? The link below shows the simulation of a hypothetical transformer with and without a Zobel network to damp ringing at high frequencies.

If one choses to use a loading network and likes the sonic results, that is fine. I have always found that sonically, loading is the worst thing you can do to a transformer and using anything more than the absolute minimum required is relying on a band-aid for a preventable injury.

I do not consider the use of the rather heavy secondary load in addition to a Zobel as a sonically acceptable solution.
FWIW they *are* designed for that.

The reality is that transformers are non linear in both amplitude and more importantly phase. It is the phase anomalies that kill the music - musical timing and natural harmonics are destroyed by phase anomalies.
