What's the point of reviewing a pair of monoblock amplifiers that costs more than most people spend on two or even several cars— and far more than most audiophiles spend on an entire music system? That's a good question. Another is: Why should I write this review when, just seven years ago, I reviewed a pair of darTZeel monoblocks that look exactly like this new pair?

I realize that products such as the darTZeel NHB-468 ($170,000/pair) are for the very few, but the very few include far more people throughout the world than you may realize— people who can afford such costly audio products and who do buy them. I know, because in my travels I've met a lot of them, and they deserve to read reviews of products they're considering buying—things most of us can only dream of owning.

Romantics rejoice! In an age where ice seems to melt faster than hearts, there are still great musicians who uphold the Russian tradition of romantic music. Vadim Gluzman, Johannes Moser, and Yevgeny Sudbin may not (yet) have the cachet of David Oistrakh, Mstislav Rostropovich, and Sviatoslav Richter, who famously came together with Herbert von Karajan to record Beethoven’s Triple Concerto, but their new SACD of Tchaikovsky’s Piano Trio in A minor, Op. 50, and Arno Babajanian’s sole Piano Trio (BIS-2372) places them firmly in the grand Russian tradition of emotive, give-it-all-you’ve-got musicianship.

In the realm of loudspeaker reviews, John Atkinson's measurements and my empirical observations have one important equivalency: Both are meaningless abstractions until confirmed by your listening experience.

Both are contingent on factors that are necessarily obtuse and not especially controllable.

One of my biggest surprises since I became the editor of Stereophile—and so started focusing more on all things audiophile—is how often I find myself thinking about the ethics of this hobby. This is unusual for me: I dislike moralism and prefer aesthetics to ethics.
