Headphone listening has always been an important part of my audiophile life. In recent years I've been using at home Audeze's large, open-back, circumaural LCD-X headphones, which I bought after reviewing them for the March 2014 issue; and a pair of small Ultimate Ears 18 Pro in-ear monitors, which provide much better isolation on my subway commute to Stereophile's offices in Manhattan. I was intrigued by Audeze's iSine in-ear models, which were introduced in November 2016 and are unique in using planar-magnetic drive-units mounted outside the ear. I thought about reviewing a pair of the affordable iSines, but before I could get around to it, I heard that Audeze was to launch a cost-no-object version, the LCDi4, priced at a substantial $2495/pair. Aspiration got the better of frugality, and I asked for a pair to review.

The Swissonor TA10, a contemporary tonearm designed for the Thorens TD 124 turntable (1959–1970), challenged me to set aside some of the things I thought I knew about phonography. On at least one of those counts, it succeeded.

Handmade in Switzerland and modeled on the Thorens TP 14 tonearm of the 1960s, the TA10 ($3990) improves on its predecessor with an effective length of 240mm, which Swissonor says is the longest that can be achieved with a stock TD 124 armboard (the TP 14's effective length was only 210mm), and replaces the non-universal plug and socket of the TP 14's removable headshell with the more common SME standard found on most contemporary headshells, pickup heads, and tonearms.

Every conductor who undertakes Mozart's Requiem must ask one fundamental question: Whose Requiem shall I conduct? After René Jacobs asked the question, he can up with a novel solution for his new period-aware, decidedly contemporary Harmonia Mundi recording of the Requiem with the Freiburger Barockorchester and RIAS Kammerchor.
