Distortion: Naughty but Nice
link to Keith
article for Stereophile,
is an excellent article, my only reservation: Mr Howard's distortion
test method didn't take into account distortion products decreasing
as the acoustic level decreases, a phenomenon which single-ended
class A amplification's distortion characteristics display (see Single-Ended
Class A by Nelson Pass).
2007: Mr. Howard and I have been in email contact regarding my
reservation above, because apparently his
distortion test method takes into account 'distortion products
decreasing as the acoustic level decreases'. Those interested can
visit his excellent website
and download his AddDistortion utility used for the tests and
experiment for themselves. (I hope to download the software soon and
learn about the effects for myself.)
