Listening I: Well-known tunes with the reference system
After that break-in period, I started listening critically using my reference system (dCS Bartók streamer/DAC, Benchmark LA-4 preamp, Benchmark AHB2 power amplifier). I had noticed during break-in that these speakers put out a lot of bass energy, more than I expected from 6.5" woofers. So I turned to my trusted Bass Test playlist on Qobuz (footnote 4). My go-to test of fast and deep bass these days is "Flea" by St. Vincent from All Born Screaming. There are deep beats, deep synth sounds, a bassline that goes to the bottom…

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),…

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…
