I used DRA Labs' MLSSA system and a calibrated DPA 4006 microphone to measure the PSB Synchrony T600's frequency response in the farfield. My reference axis for the measurements was level with the center of the midrange unit, which is 38" from the floor, slightly above the height of my ears in my listening chair. I used an Earthworks QTC-40 mike for the nearfield and in-room responses and Dayton Audio's DATS V2 system to measure the impedance.
PSB specifies the Synchrony T600's anechoic sensitivity as 89dB, presumably for 2.83V at 1m. My B-weighted…
Take a walk at night. Walk so silently that the bottoms of your feet become ears.—Pauline Oliveros, Sonic Meditations
The one activity that distinguishes audiophiles from other music lovers is our practice of sitting in solitude and listening closely to music reproduced on a finely tuned playback system.
That is not to suggest that there's anything wrong with playing music in the background. But what's unique about us audiophiles is the seriousness of intent with which some of us sit in front of or among two or more speakers, or within a headphone soundfield, and focus intently…
In New York City, everything comes at a premium: Housing, groceries, transportation, walking space, living space, sanity space—consider our cubbyhole apartments and tenement buildings. Even "air rights" are for sale in NYC, including rights to the air over my beloved Katz's Delicatessen in the Lower East Side (footnote 1). The square footage of my downtown apartment is less than a quarter of the space of my North Carolina home. (Brownstones? Only above 72nd Street, footnote 2.) But, as the song says, "If you can make it here, you can make it anywhere." What did Frank Sinatra know, anyway? He…
The EX-8 2.0 was made in Ayre's Boulder factory and voiced in the Ayre sound room with TAD Reference One speakers; the headphone outputs were evaluated via Sennheiser HD 600s with balanced connectors. Source material included CDs and files stored on the network by artists including Shawn Colvin, James McMurtry, and Igor Stravinsky.

For spinning vinyl, I used my Thorens TD 124 turntable with its Jelco 350S tonearm and Clearaudio Concept MC cart. Phono preamp duties were performed by the Sculpture A Mini Nano Step-Up (which extracted new richness, punch, and impact from my vinyl…

On its face, the Ayre Acoustics EX-8 2.0 Integrated Hub appears identical to the original EX-8 that I reviewed in February 2019. However, changes have been made to better allow the amplifier to drive low impedances (footnote 1). I measured the EX-8 2.0 with my Audio Precision SYS2722 system (see the January 2008 "As We See It") and repeated some of the tests with the magazine's APx500 system. Before performing any testing, I followed the CEA's recommendation of operating the EX-8 2.0 at one-eighth the specified power into 8 ohms for 30 minutes. At the end of that…
In the household I grew up in, telling a lie was a death-penalty offense—worse than murder or leaving crumbs on the kitchen counter. So, believe me when I tell you that way more than a year ago, Musical Surroundings' Garth Leerer sent me DS Audio's lowest priced optical cartridge, the DS-E1 ($2750 with energizer/equalizer, footnote 1). He said, "You need to know about this." Then every few months he would write and politely inquire how I was liking it. Each time I would write back saying, "I'm sorry Garth, I haven't tried it yet, but I'll install it right after deadline."
That was a score…
