I tested the Cambridge Audio CXA81 with my Audio Precision SYS2722 system (see the January 2008 "As We See It"). I first preconditioned the amplifier by following the CEA's recommendation of operating it at one-eighth the specified power into 8 ohms for 30 minutes. At the end of that time, the top panel was warm, at 98°F (36.7°C), with the grille over the heatsinks and transformer hotter, at 133.1°F (56.2°C). I then performed my usual thermal stress test by running the amplifier at one-third power into 8 ohms for an hour. After 30 minutes, the grille's temperature…

When Jason Victor Serinus reviewed the expensive Statement server from Portuguese company Innuos (footnote 1) in the April 2020 issue of Stereophile, he concluded that "Innuos has created a transparent instrument that scores big in soundstage size and depth, dynamics, and bass reach." Comparing the Statement and a sample of the more affordable Roon Nucleus + (footnote 2) (fed by a linear power supply)—both servers feeding his dCS Rossini and EMM DV2 D/A processors via USB—he found that via the Statement "the treble…

It was supposed to be so simple, a well-trod path I've followed almost every May for the last decade: A six-day trip to Munich to attend the final Munich High End Show before it decamps to Vienna next year.

I see any trip to Europe as an opportunity to replenish my personal stash of Anthon Berg Danish marzipan bars, a childhood favorite with a crack-like addictive pull. My flights and hotel were booked months in advance. I was ready to go.

Then Jim Austin, my esteemed editor, asked…

Weinstein brothers Heth and Jed (www.hethandjed.com) write catchy pop love songs with infectious melodies and subtly sophisticated harmonic structures that allude to an intellectual depth that grabs the mind and soul equally. The pair's greatest strength is their ability to formulate and elaborate electronically manipulated electroacoustic arrangements that echo early Brian Eno as much as the folk singer-…

I used DRA Labs' MLSSA system and a calibrated DPA 4006 microphone to measure the Dragonfire Mini Dragon Satellite's frequency response in the farfield, and an Earthworks QTC-40 mike for the nearfield responses of that and the SB-8P powered subwoofer. I measured the performance of the Dragonfire MD-4 power amplifier with my Audio Precision SYS2722 system (see the January 2008 "As We See It"). Because the MD-4 uses a class-D output stage, around 320mV of ultrasonic switching noise was present on its outputs. As this noise might overload the SYS2722's input…

Though nearly all of us have to factor convenience and cost into what we consume, to much of the planet's population, our mediocrity looks like an affluent fantasy. I recall my first, utterly blissful visit to a US shopping mall as a college freshman. I couldn't…

One very visible change in the C1.2 is the introduction of MQA support, which was not present in…

AC Nexus Advanced Power Distribution & Ground Enhancement System: $20,000 ★
Steve McCormack, once the proprietor of The Mod Squad, is the man who introduced the concept of accessory isolation feet—his Tiptoes were aluminum cones with flat tops and sharply pointed feet. Now he's brought to market this passive AC-power filter, whose Panzerholz enclosure contains two fist-sized silver-conductor capacitors from Duelund. The IEC AC inlet is a Bocchino Audio Marriner10 and the AC outlets are four Furutech Nano Crystal Formula duplexes. Four Cardas ground posts…
