Isolation Transformers -- Equitech or Torus?

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?

@ptss

Thats an easy answer, because the majority of dealers of any audio product has a level of knowledge only as deep as the info found on the public flyer found on the manufacturers website of the wares they are selling.

Would you contact a dealer if you wanted to know the technical details of why the torridial transformer found inside one of these devices was sufficient to power an audio system? Would you be OK taking the word of a guy with no electrical background that has a quota to meet?

I hope not  

I have an EquiTech Son of Q and it's been rock solid,  my system is dead quiet with it providing power...

Torus is not balanced. Equitech is balanced, and where most of the benefits come from.
