Isolation Transformers -- Equitech or Torus?

Both units are good, but Torus price are much more lower than Equitech,.....

Thanks everyone! Favorite/best models for Audiophiles (think sub-panel rated up to 125amps and whole-house panel 225-amp or better).

Asked Equi=tech twice in about a week to quote a price without answer. Once to Torus and had an interesting discussion with them.
at the start I gave a slight advantage to Equitech but now I imagine if I deal with them and need an aswer or have some trouble to fix and they don't answer... What do I do ?
As I live in Europe I need to be assured for these things as it is difficulté to phone direçtly in the USA technical spoken language etc.

I am about to buy a Torus one. Until ow I only had pasive conditionner because I want to connect everything without any loss in dynamics. I had the Lessloss first model that was great until I listened to a Bybee Stealth that I traded in when he made the new Crystal technology for the Holographic I have until now.
my current is not that good and sound quality varies fro mtime to time. So I looked something for preserving from that changes and put me independant from that noise. The only way I found is active isolation transfos. I looked at the forums and reviews and selected Equi=Tech and Torus. I am in Europe and Equitech never answered mu emails. Torus instead answered and gave me all the infos I needed.
I privately talked to a guy that has a WM90 Torus and he is so happy with it that he sold back the Shunyata Triton he previously wanted to keep connected to the Torus and feels better like that.
Now that I am very near to make a decision I see that some consider JMF Audio as better. I went on their website and there is not much explanation about the technical elements that leads them to their conditionner.
Does someone has opinion or experience with Torus vs JMF or another

Why contact Equitech directly instead of a dealer? Would you call GM to for prices? Or perhaps a dealer?
