During a century of development of the phonograph, dozens of different things have been considered crucial to its performance: lack of bearing noise, lack of motor noise, freedom from runout error in the platter, high moment of inertia in same, immunity to all manner of unwanted vibration, and so forth. But now I wonder if the most important factor of all hasn't been overlooked, or at least misunderestimated, throughout much of that time: Could it be that motor <I>torque</I> is more critical than any of us imagined?

I'd been curious about Phiaton's headphones ever since Wes Phillips's positive review of the radical-looking, leather-clad <a href="http://www.stereophile.com/headphones/phiaton_moderna_ms_400_headphones… MS 400</a> appeared in our pages earlier this year, so when I learned that a couple of Phiaton's executives would be in New York City to introduce their new noise-cancelling 'phones, I was eager to check them out.

Clad in red leather and light as a feather, the frigging luscious <a href="http://www.stereophile.com/headphones/phiaton_moderna_ms_400_headphones… Moderna MS 400</a> headphones have a way of caressing your silly skull.

The Phiaton PS 300 NC headphones ($299) use Valves of the Heart Sound Technology (VHST) to control airflow into and out of the headphone speakers.

The Phiaton PS 200 sound-isolating earphones cost $249 and are designed to resemble jet engines! John Atkinson is working on a review.
