I used DRA Labs' MLSSA system, a calibrated DPA 4006 microphone, and an Earthworks microphone preamplifier to measure the Sonus faber Sonetto V G2's quasi-anechoic frequency- and time-domain behavior in the farfield. I used an Earthworks QTC-40 microphone, which has a small (¼" diameter) capsule, for the nearfield responses.
The Sonus faber loudspeaker's voltage sensitivity is specified as 89dB/2.83V/m; my B-weighted estimate was 88.6dB(B),…
With a computer as a source, I listened to Doug MacLeod's "Sweet…
Audio Thesis’s biggest announcement
Audio Thesis’s biggest announcement was the global launch of Turnbull Audio. Not to be confused with Devon Turnbull of OJAS fame, this Turnbull is a cable company, which outfitted the Audio Thesis room at CAF.…
Sandy Gross, veteran and founder of Polk Audio, helped choose the drivers and contributed to the design, I was told. And they were selling for $498 apiece.
The LC1 cabinet exploits a composite, multi-layer, high-mass, non-resonant material, features a 1” dome tweeter, a 6.5” polypropylene cone…
It's important for readers to remember that I've spent my adult life as an artist and mechanic. Making things. Working as a tradesperson during the day then at an easel or workbench at night.
When I finished high school, all I wanted to do was work in a fancy, well-equipped shop building drag race engines. Engine building was something I had already shown a talent for, but my parents insisted I go to college. Unfortunately, my high school grade point average was so low I was turned down by every college I applied to. Consequently, my parents forced me to…
Since I reviewed it in Gramophone Dreams #79, the EVO 100 has refused to make my system sound warm, soft, or second-harmonic thickened. It defies all clichéd descriptions of what tube amplification sounds like. Instead, it plays clean and fast and corners like a race car.
When Kevin Deal emailed asking if I was ready for a "free" EVO 100 "upgrade," I asked, "What's wrong with the way it is?"
He responded, "It's a parts upgrade and circuit tweak. We could do the MKII BS to raise the price, but we don't roll that way. Our job is supplying joy, not cashing in. Doing it free…
The speakers are made on the Chesapeake Bay by local artisans who use a local mill to provide wood for their hardwood designs, which borrow from local nautical history, according to the company’s Buff Colchagoff.
EBS’s Southwind standmount ($1450/pair) is a mass-loaded Voigt pipe (mass-loaded horn) designed for the Markaudio CHR-90 5½” full-range drive unit. The cabinet’s inner box is ½" Baltic Birch plywood, and the outer box is ¼" Walnut, with Maple and Cherry hardwoods.
“Both the alloy…
The setup saga began when Moon co-owner Costa Koulisakis traveled to Port Townsend from Quebec to help remove two 861 amplifiers from their sturdy flight cases and set them up. (We also set up the Moon 891 Network Player/DAC, which I'll review next month, with and without the 861s.) First, he noted that Moon designed the 861 to rest…
Details
The Moon 861's attractive front panel is blessedly free of bells, whistles, and unnecessary clutter. It includes a discretely placed button that toggles the amp between "active" and "inactive" modes (ie, on and standby), and a status indicator light that differentiates between powering up, normal operation, and firmware update status. The light's unusual placement and shape add to the amp's distinct aesthetics.
There's more action on the rear. Beyond two pairs of speaker output posts and single pairs of balanced and single-ended inputs, the rear panel holds toggle…
