Putting Soulution's best to the test
Depending on how high on your rack you wish to place the 727, you may need assistance hoisting its 62lb into place. Although it comes with its own specially designed feet, I placed Wilson Audio Pedestals beneath it because (a) I use them under my reference preamp and other components, and (b) listening confirmed that they contributed a bit more air and depth to the sonic presentation. Depending on the sonic isolation and sound of your rack—few supports have no sound of their own—your results may differ.
During the review, I auditioned the…

I measured a different sample of the Soulution 727 preamplifier than that auditioned by JVS. Mine had the serial number 727-0053. I primarily used my Audio Precision SYS2722 system to measure the Soulution, repeating some tests with the magazine's higher-performance APx555.
Looking first at the performance of the 727's line-level inputs, the maximum gain for the balanced and unbalanced inputs to the balanced outputs was a little lower than the specified 4dB, at 3.7dB. The maximum gain from the balanced and unbalanced input to the unbalanced outputs was –2.…
My old pal George Stanwick, who worked at Stereo Exchange, spotted me walking up Broadway through the store's window, whereupon he ran out and literally dragged me off the street pulling me by the arm—against my mumbled protests.
I followed George into Stereo Exchange's luxurious back room, where, spotlighted in front of me, I saw what looked like an expat's spin on trad-…
Listening
I collect black discs from the early 1950s because back then the vinyl was thick and heavy and its labels and covers used superior quality inks with super-saturated colors, often with gold or silver metallic lettering. My favorites among these classic beauties are discs made in Britain by EMI, Decca, and Argo. Lately, I've developed a special fondness for mono Argos pressed in England during the late '50s to early '60s. Their sound has a burnished gleam I find uniquely appealing.
On the first day of my Totem Element Fire auditions, I played my favorite composer,…

I used DRA Labs' MLSSA system, a calibrated DPA 4006 microphone, and an Earthworks microphone preamplifier to measure the Totem Element Fire V2'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 and Dayton Audio's DATS V2 system to measure the impedance magnitude and phase.
While the…
