Question Toroid RF Noise

I would re-state what Borisov57 said, a Toroidal is really good for injecting RF Noise in to whatever circuit, and I would imagine this would be worse for the digital side of things. Audio Amateur did an article on this subject, from my own experience, I well remember that a old Naim NAP120 (that was available with frame and toroidal transformers), the frame transformer type always sounded nicer. I'm not paranoid about this and I still use toroids, but I would not recommend changing from a frame type to a toroid. I've never had any hum problems with frame transformers, if there is hum its usually a symptom of incorrect grounding.
