Headphone Reviews

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.

Every day in my bunker, I use one of a few high-quality headphone amplifiers to double as a line-level preamplifier-controller and operate as the quality-assurance reference for my ongoing audio experiments. I must choose this component carefully, because it determines the upper limit of my system's ability to reveal any subtle differences among components under review.

In equipment reports, I use the phrase forward momentum to refer to something a little deeper and more encompassing than what's meant by that well-worn Brit-fi expression pace, rhythm, and timing (PRaT). Pace refers to the speed at which a piece of music is being played, and the accurate reproduction of that speed requires audio sources with good dynamic pitch stability. (Digital folk always lord it over LP clingers for digital's superior pitch stability.)

For digital playback, in recent months I've been breathing some rarefied air, pricewise. In December 2016, I reviewed dCS's Rossini Player and Clock, followed in May 2017 by Meridian's Ultra DAC, and in June by Chord's DAVE DAC. The Rossini Player costs $28,499 without the Clock, the Meridian $23,000, and though the DAVE is less expensive than either at $10,588, that's still a fair chunk of change. Even PS Audio's PerfectWave DirectStream DAC, which I bought following Art Dudley's review in September 2014, costs $6899 with the Network Bridge II, which hardly counts as "affordable."

Before he left Stereophile for AudioQuest at the end of March 2014, Stephen Meijas asked Thinksound to send me the On1 closed-back heaphones. He thought I might like them.

Cool beans, Stephen. I do. These are among the nicest 'phones I've come across lately. List price is $299.99, but the street price—sometimes directly from Thinksound—is usually $249.99. You save an imaginary $50. That's $50 of your savings that you can share with me in Bitcoins.

I figured it was coming, but it wasn't until just after I'd returned from the Audio Engineering Society's 2016 International Conference on Headphone Technology—held last August in Aalborg, Denmark—and was writing up my report and summary on the event for InnerFidelity.com (footnote 1) that I knew for sure: Headphones are about to change . . . a lot.
