For Jason Victor Serinus, one of the highlights of the 2013 T.H.E. Show in Newport Beach, California, was the public debut of the Sopranino—a horn-loaded, self-polarized, electrostatic supertweeter from EnigmAcoustics. In his report, Jason wrote about the sound of a pair of Sopraninos used atop Magico V3 speakers: "only folks with severe hearing loss would have missed how the sound opened up when the Sopranino was switched in." Well, as you can read later, I don't have hearing loss, and I did also hear an improvement with the Sopranino. So when I visited the Californian company's dem room at the 2014 Consumer Electronics Show, in Las Vegas, I asked for review samples.

Introduced nearly eight years ago as the first recordable digital format for consumers, DAT both failed to appeal to its target market and was blocked from formally entering the USA for four years by the RIAA, who feared for the copyright of its members' recordings. However, the DAT medium was enthusiastically snapped up by professionals and semiprofessionals, who found its combination of reliability, CD-compatible signal format, and editing ease ideal for mastering. Sony currently offers a small range of consumer models, from the diminutive Walkman-sized TCD-D-7 DATMan to four-head cassette-deck–sized machines for the so-called "prosumer": amateur recordists who make pin money taping local concerts. The DTC-2000ES is Sony's latest entry (footnote 1).

I walked into BSG's room at the Newport Beach Show in June 2012 unsure of what I was going to hear. I was well aware of this new company's qøl Signal Completion Stage ($3995), but didn't know if it was a genuine step forward in audio reproduction, or just another example of the hokum found on the fringes of our hobby. I took my listening seat, and BSG's CEO Larry Kay, cofounder and erstwhile publisher of Fi magazine, performed A/B comparisons with the qøl's processing in and out of circuit.

Erick Lichte mentioned Totem Acoustic's Beak, which costs $125/pair, in his follow-up review of the Totem Forest loudspeaker in January 2010. The Beak is a bullet-shaped device, about 2" high by 1.5" in diameter, that's intended to be placed atop a speaker to control "parasitic resonances." I was given a pair of these more than 10 years ago, and have tried them with various speakers. While Erick didn't find the Beaks to make any difference to the sound of the Forests or any of the other speakers he had to hand, my experience was different.

I have been a proponent of methodical modeling and room analysis as aids in setting up audio systems and rooms. They work hand in hand: Modeling predicts a feasible room arrangement, and analysis, along with careful listening, determines how close the outcome is to that predicted. Of course, there should always be another round of modeling to see if the current setup can be improved with more work. The spiral continues, toward, one hopes, perfection.

Because I'm suspicious of just twiddling knobs to make the sound "nice," I didn't rely solely on my ears when I used the Z-Systems rdp-1 that I review elsewhere in this issue for speaker and room contouring. Instead, I used the ETF speaker/room-analysis software from Acoustisofthttp://www.acoustisoft.com">Acoustisoft; to help me manipulate the equalizer properly. This program can measure the first-arrival, on-axis speaker response, as well as the room response with its early and late reflections and its resonances.
