Isolation Transformers -- Equitech or Torus?

There are a number of threads on power on the forums but I don't recall one where someone states one or the other of these brands of isolation transformers is superior to the other though each has their following. Would like to see what you get back in answer to this question as this may be a direction I go in the future for my system....

Silver Circle TCH 6 is the BEST!!

Torus is a much easier company to deal with.

Thank you.....for an install where the i-transformer would be used to drive power to a 125amp sub-panel for listening room, which is the best model overall for us audio-nuts' concerns?

I've had great experience with Equitech, and this is the first I have heard about them not being easy to deal with.

Love my 2Q, but have not heard Torus.
