Headphone Reviews

When Stereophile publishes a followup review in the print magazine, we add it as a "child page" to the website reprint of the original coverage. We have recently done so with three significant products: the Magico M2 loudspeaker, the Linear Tube Audio Z10e tubed headphone amplifier/integrated amplifier, and the Okto Research dac8 PRO multichannel D/A processor.

I am certain the quality of life I live is determined by two factors: who and what I give my attentions to, and my ability to observe all that I encounter with an open mind. This approach to living has served me well—especially during this review of the Benchmark Media Systems HPA4 headphone amplifier ($2999).

In February 1994, when I reviewed the pricey ($12,900 with amplifier) Sennheiser Orpheus headphone system—HE 90 headphones and HEV 90 D/A processor/amplifier—I commented that the company had a similar, but less expensive, alternative available: the HE 60 headphones combined with the HEV 70 amplifier. At the headphone end, the HE 60s aren't so different from the HE 90s furnished with the Orpheus system. Both are extremely lightweight and supremely comfortable—even for long listening sessions (I logged up to four hours without a break on the HE 60s). In fact, the less-expensive HE 60s are about 100gm—4 ounces—lighter than the HE 90s.

Today is March 22, 2020. Outside my door, the plague is gaining intensity. People are wearing masks and rubber gloves. But outside the window by my desk, there is a Callery pear tree, and every day its blossoms are becoming more intensely white. Each day its brightness (measured in units of luminous flux) increases noticeably. The optical radiance of its zillion-petal whiteness illuminates the whole garden.

Almost a year ago, a headphone pal loaned me the Zach Mehrbach–designed ZMF Auteur LTD headphones. He said, "Herb, see if you like these." I took them home and right away thought, Wow, these headphones really disappear!

Nothing about their sound attracted my attention. The only thing I noticed, casually, was how relaxed and unbelievably transparent they were.

My current romance with audiophile-quality headphones began in earnest with the appearance, about 10 years ago, of Audeze's LCD-2 planar-magnetic headphones—these predated the company's patented Fazor elements, said to guide the sound around the transducers' magnet structures—and Schiit Audio's original Asgard headphone amplifier. Together, these groundbreaking products rekindled my interest by making headphone listening into something new and exciting—something less distorted, more dynamic, denser, and more intensely lifelike than what I was getting from my speakers on the floor. Best of all, I could listen while lying in bed with my eyes closed.

I have on hand a number of pairs of headphones. And I admit that I've lusted after the heavenly sounding, medieval-looking Abyss AB-1266 Phi headphones, and considered the MrSpeakers Aeon closed-back headphones. (I prefer the isolation from outside sounds provided by closed-back 'phones.) But from the moments I saw—and then heard—Meze Audio's 99 Classics, with their graceful style, balanced sound, and natural wood-grained glory, they had me.
