T.H.E. Show was slow to complete the website for this show; locating the online press portal was a challenge. At the event itself, signage was subpar: Demo rooms were somewhat scattered, some…

I used my Audio Precision SYS2722 system to measure the HiFi Rose RA280. While the manufacturer describes the RA280 as a "class-AD" design, it appears to have a class-D output stage for its two channels. Because class-D amplifiers emit relatively high levels of ultrasonic noise that would drive my analyzer's input into slew-rate limiting—the RA280 emitted enough RF noise to interfere with reception on the portable FM radio I keep in my test lab—I inserted an Audio Precision AUX-0025 passive low-pass filter between the test load and the analyzer. This filter…

Sound quality is just the beginning. Consider economics. An integrated amplifier is gentler on the wallet than often-cumbersome separate pre and power amplifiers. It's the Marie Kondo of the audio world, decluttering your hi-fi rack with hardnosed efficiency. Fewer connections mean even more value—fewer expensive cables—less fuss, and a refined, all-inclusive electrical architecture tucked into one (often but…
Adrian Belew had an itch that needed some serious scratching. The iconoclastist/vocalist had a hankering to perform material from the three King Crimson albums he fronted during the proto-prog band's 1980s revival—October 1981's Discipline, June 1982's Beat, and March 1984's Three of a Perfect Pair—but how could he go about it in a way that pays respect to and expands upon their original intent, all at once?
First order of business: Make sure King Crimson founder and guitar visionary Robert…
