Hi-fi firms have begun in garages. The English Spendor company was started in a bathtub. Or was it a kitchen sink?

By days in the late 1960s and early 1970s, Spencer Hughes worked as part of the BBC's loudspeaker research team. Among other accomplishments, he helped develop the 5" midrange/woofer for the fabled LS3/5A loudspeaker.

To audiophiles who are aware that their household line voltage changes under varying loads, and have observed the absolutely fantastic differences in the sound of their system when the next-door neighbor turns on Junior's night light, it may come as a surprise to learn that there are folks out there who think you're full of crap. That's right, Virginia, they don't think you can really hear all those things you pretend to hear. (You are only pretending, aren't you?) They can't hear all those things, so how can you? Well, sometimes they can. They'll even admit that. But those tiny little differences are so trivial that they don't matter no more than a fruitfly's fart. That's the word in scientific circles these days. Or haven't you been following the "establishment" audio press lately?

Natural sounds produce different waveshapes during their positive and negative phases, and playback-system polarity reversal often changes the reproduced sound. Does this mean our ears are phase-responsive, or is there something else here we've been overlooking?

There has been much discussion recently among perfectionists about the importance of what is called "absolute phase" in sound reproduction. Basically, the contention has been that, since many musical sounds are asymmetrical (having different waveforms during positive and negative phases), it is important that a system make the proper distinctions between positive (compression) and negative (rarefaction) phases in playback.

This is not nostalgia. Far from it. The man still has much to say. His gifts have grown richer. And the devil is a waitin’

Register to win a pair of Vanatoo Transparent One Speakers (MSRP $499.00) we are giving away.

According to the company:

"The Vanatoo Transparent One powered speakers set a new price/performance benchmark in the audiophile world. They produce unexpectedly great sound quality (honest, tight bass down to 48Hz!) from small bookshelf speakers that give you a lot of flexibility in how you use them. They are equally at home as a desktop audio system, a music streaming solution for a room where you want music but not stacks of equipment, or as a compact system you take with you on your weekend getaways."

Can a power-supply upgrade produce audible sonic benefits? If you've upgraded the power supply of a phono preamplifier, you probably don't need to be convinced that it does, and those usually cost only a small percentage of the price of the model they power. But to add Simaudio's Moon Evolution 820S power supply ($8000) to the Moon Evolution 650D DAC–CD transport ($9000), which I reviewed in the November 2011 issue, almost doubles the latter's cost—though the 820S can be used to simultaneously power two Moon Evolution components, like the 750D DAC ($14,000), 740P preamplifier ($9500), and 610LP ($7500) and 810LP phono preamplifier ($13,000).

It's no secret, especially to those who've been following Stereophile for more than a short time: In the first half of 2007, I took the plunge and bought a Shindo preamplifier and monoblock amplifiers—handmade products characterized by low output power, generous numbers of vintage parts, steel casework finished in a signature shade of green, and richly textured, impactful sound with lots of sheer musical drive. And while we tend not to alert the major newspapers whenever someone on staff buys new electronics, the change was notable for two reasons: The compatibility of Shindo's amplifiers is limited to loudspeakers of higher-than-average sensitivity and impedance; and, throughout the seven years that followed my switch to Shindo (footnote 1) both my system and my point of view regarding domestic audio in general have evolved in the direction of the artisanal and the vintage.
