In Reply to: My take from that Paul McGowan quote posted by 1973shovel on June 3, 2013 at 14:57:24:
You state ..."Was that it was the larger transformer's lower secondary impedance which caused the "jaw dropping" improvement, not the over-kill in amperage potential."
These ( low impedance and high current rating ) are essentially one and the same thing !! A high current ( high amperage ) secondary will be wound with thicker wire, which IS lower in DCR, and which likewise IS lower in impedance.
The way to get "low DCR " and a "lower impedance" from a typical transformer winder is to specify a high current-rating transformer. They will then design and wind it to be BOTH low in DCR and it is ALSO low in impedance !!! Its like love and marriage, "you can't have one without the other".
Both the primary and the secondary has to be low in DCR for the most effective result, not just the secondary alone. I always specify DCR on the primary and secondary in my custom winds.
