Never Mind the Bollocks was out, on a major label. A few months before, the Ramones had released their third album, Rocket to Russia. Elvis Costello's My Aim Is True had been out for a while, but it was still a game changer. Soon, Darkness on the Edge of Town and Some Girls would all be vying for attention. That was college radio circa 1978. And amongst all this progressive talent was even a flash of…

A quick scan shows that Rogue Audio has been prominent in Stereophile. The magazine has reviewed quite a few Rogue Audio products, including the RP1 preamplifier, the several versions of the Sphinx integrated, the Pharaoh II integrated, and the Stereo 100 power amplifier. Indeed, Rogue has had a near-continuous presence over the past decade on Stereophile's coveted "Recommended Components" list. That's an impressive track record, and accessibly priced…

I performed a complete set of measurements on one of the Rogue DragoNs (serial number DRAM-0551) with my Audio Precision SYS2722 system.

As the DragoN has a class-D output stage, I inserted an Audio Precision AUX-0025 passive low-pass filter between the test load and the analyzer. This filter mitigates noise above 80kHz and eliminates noise above 200kHz that would otherwise drive the SYS2722's input circuitry into slew-rate limiting. Without the filter, there was 408mV of ultrasonic noise with a center frequency of 416kHz at the amplifier's output terminals…

I recently received a letter (not yet published) suggesting a need for a glossary of newer hi-fi terms (footnote 1). Some audiophiles raised on physical media, it seems, are perplexed by descriptions of the new streaming landscape. Just yesterday, all we had to worry about was DACs and transports. Today we have servers, streamers, players, streaming DACs, and all that. That immediately struck me as a good idea, allied with a second reason: To avoid…

From Afar seems on its face like a dream recording for audiophiles and music lovers. The 2-CD, 44-track project spotlights Víkingur Ólafsson, the sensitive, 38-year-old Icelandic pianist, performing a captivating program of short pieces twice on dissimilar pianos with very different sound: a concert grand and an upright. The very different performances are dictated by Ólafsson's…

What differentiated this show from any other is that it was put together by a single dealer (Audio Advice, which also has a store…
