Throughout the summer and fall of 2016, I worked on a project with Stereophile contributor Sasha Matson, recording, editing, mixing, and mastering—for release on 180gm LP, CD, and high-resolution download—an album of works that Sasha had composed for various chamber ensembles: Tight Lines. As you can read in the article we published about this project, for the vinyl release we decided not to master the discs directly from the hi-rez files, but to create an intermediate analog tape master. Feeling that audiophiles would want an LP that at some stage was "analog," we therefore needed to choose a D/A processor to drive the Studer open-reel tape recorder we were going to use.

Following my review of the floorstanding Magico S5 Mk.II last February, I spent some time with two-way stand-mounted speakers from Aerial Acoustics, Bowers & Wilkins, and Dynaudio. As much as I appreciated the small speakers' virtues, I found myself missing the big Magico's bass extension and ability to play loud; my next loudspeaker review, therefore, would be of another floorstander.

It's been a while since we published a review of a Rockport Technologies loudspeaker.

The first room I went to at the 2017 LAAS was that hosted by LA dealer Optimal Enchantment featuring a system based on Vandersteen's Model Seven Mk.II speakers ($62,000/pair) and M7-HPA amplifiers ($52,000/pair), which I reviewed in May 2016, this time reinforced by a pair of Vandersteen's SUB NINEs operating below 100Hz. It may have been the first room I visited but as good as many other systems sounded, they didn't match what Vandersteen refers as System NINE for its effortless sweep of sound, precise, palpable imaging, and smooth yet detailed high frequencies.

I tend to be skeptical of tweaks. Too often in the past, I have heard an astonishingly audible difference when the whatever is demonstrated by its promoter, only for any difference to stubbornly disappear when I try the same thingamabob in my own system. But listening to the difference when Isotek's Bjorn Hegelsted replaced the cheap power strip and stock AC cords in a MoFi Distribution system using the impressive but affordable Wharfedale Diamond 225 speakers ($449/pair) driven by a Quad Artera Play CD player ($2199) and Artera Stereo amplifier ($2299) with a star-wired, 6-outlet Isotek Polaris conditioner ($495) and Isotek Premier AC cords ($149 each), the improvement in image palpability and dimensionality, the elimination of "shoutiness" on female voice, was extraordinary.
