I tested the Cambridge Audio EVO 150 with my Audio Precision SYS2722 system (see the January 2008 "As We See It") then repeated some tests with the magazine's more recent APx555 system. As the amplifier has an output stage operating in class-D, I inserted an Audio Precision auxiliary AUX-0025 passive low-pass filter between the test load and the Audio Precision analyzers. This filter eliminates RF noise that could drive their input circuitry into slew-rate limiting. I used it for all the loudspeaker output tests other than frequency response. After two hours of…
Adoption of DSP-based speaker-and-room correction in home theater—a parallel universe to audiophilia—is almost universal. It's easy to understand why. Home theater matured in the digital age. Its fans were expected to install several loudspeakers in a full-range setup that included at least one speaker—the subwoofer(s)—that functioned exclusively in the problematic bass region. Setup issues were intimidating.
Help quickly came in the form of setup utilities that required no knowledge of acoustics—only a willingness to position a microphone for a series of measurements and let the system…
Select some music and, while it is playing, download and install Dirac Live. Start the Dirac Live program, and it opens with a big Dirac Live 3 logo (yeah, I know). The software then verifies your Dirac account (with account information you provided at purchase) and scans the system for your Dirac Processor. Click on it—most users will have only one—and proceed to the subsequent menu options.
Select Recording Device: Select a microphone and load its correction file. Any USB measurement mike will do as long as it comes with a correction curve file, preferably for a vertical (90°)…
Sidebar 1: Dirac Live Bass Control
With Dirac implementations in AVRs or pre-pros, bass management has long been the responsibility of the host device; it was not included in Dirac—until now, or anyway, soon. Dirac Live Bass Control (DLBC) is an important new feature, providing bass management with potential to better integrate subwoofers with each other and with the main speakers. DLBC has already been implemented in a few AVRs, and Dirac sent me a beta version for Windows. I added three SVS subs—two SB-3000s and an SB-2000 Pro—to create a 5.3 system. Because that configuration isn't…

In May of 2019, I heard about a promising jazz vinyl and hi-fi estate sale happening on New York's Upper East Side. Little did I know then what treasures the dig would yield.
Jazz Record Center's Fred Cohen had called from the UES apartment, the former residence of late CBS Records and Sony Entertainment mastering engineer Harry N. Fein. Fred said, "The records are kind of beat, but the apartment is jammed with tape decks, turntables, cartridges, tubes, midcentury modern furniture—get up here."
I called NYC turntable technician Mike Trei, who's always up for a dig. Upon picking…
Geist believes that today's often bass-dense music formats are better reproduced with acoustic suspension speakers. "Today, recordings are ... not restricted below 50Hz," he proffered. "Bass-reflex designs really struggle with anything below the tuning frequency of the port. Their output falls off a cliff, and the system becomes unstable. The acoustic suspension design ... [relies] on the air spring the sealed enclosure provides. This air spring is never compromised, so the system output is more stable throughout the low-frequency spectrum."
