When I got to high school, I joined the debate team. (To intimidate the competition, my debate partner and I used to wear bow ties. It worked.) One day, during practice, a varsity debater who was also an audiophile saw me reading Stereo Review and berated me for reading such a "low-class rag." Condemnation and hyperbole come easily to high school debaters. A few days after chastising me, he came up to me and said, almost apologetically, "Here—this is a real audio magazine," and handed me a stack of his father's back issues of the old digest-format Stereophile.

I examined the Rogue M-180's measured behavior using mainly Stereophile's loaner sample of the top-of-the-line Audio Precision SYS2722 system (see the January 2008 "As We See It" and www.ap.com); for some tests, I also used my vintage Audio Precision System One Dual Domain.
With two output-transformer taps, two output operating modes (triode and ultralinear), and two inputs (unbalanced and transformer-coupled balanced), the M-180 is basically eight amplifiers in one chassis. After checking the bias, I performed a complete set of measurements from each tap…
Tice Clock: Are there two more loaded words in all of hi-fi?
For those too young to know: In 1990, an audio manufacturer named George Tice brought to market a $350 accessory that could improve the sound of any domestic music system, simply by being connected to an AC outlet in the same room—or so he claimed. But the claim was incredible, because the product appeared to be nothing more than a rebadged RadioShack digital alarm clock to which an invisible "proprietary treatment" had been applied. Stereophile borrowed and tested various…

Ivor Tiefenbrun, founder of Linn, told me 25 years ago that CD players were fine for "little old ladies with shaky fingers." I am neither a lady nor little. And so far, I am not shaky. But I'm too old to fuss much with LPs, which I regard as a flawed medium in its own right and worthy of respect but not veneration. Still, I remain analog-retentive.
Most preamps these days do not offer onboard phono stages. If they do, it's an option that's not always…
