John Atkinson sets the stage
Nothing seems to polarize people as much as the vexed question concerning the importance of audible differences between amplifiers. If you think there are subjective differences, you're an audiophile; if you don't, you're not. And as any glance at an appropriate issue of Consumer Reports—the publication for non-audiophiles—will confirm, the established wisdom is that once the price of an amplifier or receiver crosses a certain threshold, any further improvement in sound quality becomes irrelevant, in that it puts the price up for no apparent gain. In other words, when it comes to amplification, there is such a thing as being "too" good. Yet, as a reader of this magazine, I would expect that not only have you been exposed to real subjective quality differences between amplifiers that Consumer Reports would regard as sounding identical, you have made purchasing decisions made on the basis of hearing such differences.

Some of the most innovative thinking on hybrid circuit design these days seems to come from Russian designers. As a group, they are technically very well educated, pragmatic, and unfettered by American high-end didacticism.

Thirteen Ways of Listening to a Recording Session (with apologies to Wallace Stevens): Wes Phillips

Compuserve's CEAUDIO forum has been buzzing in recent weeks about audio cables. The subject even spilled over into an April meeting of the New York chapter of the Audio Engineering Society (see Wes Phillips's report in this month's "Industry Update"). Nearly two decades after Polk, Fulton, and Monster Cable raised our collective consciousness about the differences cable choice can make in an audio system, the debate still rages between audiophiles and some members of the engineering community. "High-priced tone controls" is how some engineers dismiss the subject of cables, while admitting that they can sound different. Other engineers adopt the "Hard Objectivist" line that if there are differences to be heard between cables, differences in the lumped electrical parameters of resistance (R), inductance (L), and capacitance (C) are all that are required to explain such differences.
