Why have you chosen EI vs toroids? The latter emit less.

Hi Jarek,

Yes, toroids can leak less magnetic flux than EI if they are wound such that the entire core is covered, but is flux leakage a problem if you are able to keep the transformers away from sensitive circuits?  Toroids come into their own when you are forced to mount the transformer near the circuits, but otherwise EI have them covered on most fronts.

EI

Personally, I would use EI in just about every situation for audio...unless I had no option but to tuck the transformer in tight to a sensitive circuit.


Cheers,

Anthony
