the pair. Tested samples on loan from man-

Editor’s Note: I hasten to point out,

before the self-righteous element in the

audio community does, that Don Keele is

currently employed by Harman/Becker

Automotive Systems, which is owned by

the same parent company as Infinity Sys-

tems, namely Harman International.

Harman/Becker and Infinity are totally

independent of each other, without any

overlap; in fact, they are located 700 miles

apart—but they are connected via Sidney

Harman’s pocket. He, or more precisely his

company, owns a significant percentage of

the audio industry, so that any one of the

limited number of truly qualified audio

engineers (like Don Keele) has more than

a small chance of falling within his

purview. It can’t be helped. As I pointed

out in one of the earliest issues of

The

Audio Critic, in the late ’70s, the alter-

native is to use reviewers totally uncon-

nected to the audio industry, such as

audiophile dentists. O

ther magazines do

Unfortunately, said dentists don’t know the

difference between MLS and ETF, and

that matters to me more than our

reviewers’ affiliations. I can assure you, in

an event, that no one at the corporate of-

fices of H

arman International even knew

about this r

eview

, let alone influenced it.
