Checkpoint SA-S P-770 laser alignment tool
In a sidebar to his">http://www.stereophile.com//loudspeakerreviews/542/">his review of the B&W DM302 speakers in the October 1997 issue (Vol.20 No.10), Wes Phillips mentioned a handy tool he uses for speaker setup—a laser level. The one Wes used was originally intended for construction work, not tweaking one's speaker placement, but now there's one available specifically for that purpose: The 770 SA-S Laser Sound Alignment System by Checkpoint Laser Tools.
dbx 14/10 graphic equalizer
Although most audio perfectionists look down with scorn on equalizers, there are times when the benefits of such devices can outweigh their disadvantages. I discussed the pros and cons in my review of the Accuphase G-18 in Vol.11 No.4, but a brief recap here won't be amiss.
ELAC Technische Software CARA 2.0 computer program
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.
ENIGMAcoustics Sopranino electrostatic supertweeter
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 Sopraninoa 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.
ETF, or How I Learned to Love My Equalizer
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.
FollowUp RoundUp
When Stereophile publishes followup reviews of various kinds in the print magazine, we add the followup as a "child page" to the full review. That means that they don't appear on the website's home page and might get missed. The October 2020 issue included three followups: of the Boulder 2108 phono preamplifier, the Weiss DAC502 D/A processor, and the IsoAcoustics Gaia loudspeaker isolation feet.

"Cool bag! Can I see it?"
IsoAcoustics Orea Audio Equipment Isolators
After I'd concluded my critical listening sessions with the PS Audio Stellar M700s that I review elsewhere in this issue, I got a call from Dave Morrison of IsoAcoustics, in Markham, Ontario, makers of the Gaia loudspeaker isolation feet. He told me that they had a new product, the Orea, that applies to audio electronicspreamps, power amps, DACsthe isolation technology used in the Gaia.
LG V30 Hi-Res smartphone with MQA
"Phones are the gateway device," proclaimed Marc Finer, executive producer of the Hi-Res Pavilion, at the start of the 2018 Consumer Electronics Show. When he pointed to LG Electronics' V30 Hi-Res+MQA smartphone, which includes streaming apps for Qobuz, Tidal, and YouTube, I sensed the truth in his words. The latest stats from survey company MusicWatch confirm that at least 87% of smartphone owners use a music-streaming service, including the largest, YouTube. Twenty percent of owners said that they stream music/music-related content daily, and 39% stream five or more days per week.
Nordost QNet network switch & QSource linear power supply
"A switch? Why do I need a switch?" That was my response to Meredith Gabor, head of marketing and PR for cable and accessories manufacturer Nordost, after she dropped the news. She had just arranged with Jim Austin for me to write a shorter, "ancillary" review of the new Nordost QNet Network Switch ($3199.99) with its optional QSource linear power supply ($2749.99) and premium QSource DC umbilical interface cables ($339.99 for 1m). Why did I need an expensive QNet switch when my router was functioning reliably? Good question.
