And here it is again (Asylum link below). A quote from Paul McGowan in a Stereophile interview, explaining how Stan Warren "discovered" that a more current capable power transformer sounded better.
You nailed it, Barry. McGowan said the improvement was due to the larger transformer's "very low secondary impedance".
I've always tried to build my power supplies with far more than necessary current capability (when possible) because of this. A five amp transformer doesn't cost all that much more than a one amp, in the big scheme of things. Getting it to fit in an enclosure is another matter though.
Inside that Asylum post is a link to the whole Stereophile interview with McGowan, where I got the quote.
