When Pass Labs is mentioned, it's natural to think of its founder, iconic engineer Nelson Pass. But Nelson heads a team of engineers at the California company: Their XP-30 preamplifier, which I enthusiastically reviewed in April 2013, was designed by Wayne Colburn; and the subject of this review, the HPA-1 headphone amplifier, is the first Pass Labs product designed by Jam Somasundram, former director of engineering for Cary Audio. Somasundram joined Pass Labs in July 2013; he spent a year working on the HPA-1, which was shown at the 2015 Consumer Electronics Show, in Las Vegas, but not formally launched until the 2016 CES, at a hefty $3500.

My lifestyle consultant warned me not to review Zu Audio's Soul Supreme loudspeaker ($4500/pair).

"Why not?" I asked. "They're exciting and super-enjoyable."

"Zu speakers are not mainstream," he explained. "People either love them or hate them. They're for music lovers, not audiophiles."

"That's not true!" I whined like a disappointed child. "They play Nina Simone and Aretha Franklin with spooky soul and natural tone! They play big classical orchestras—especially with trumpets and timpani—with radical ease and full-tilt momentum! And . . . and . . . they project large soundstages! Isn't that what audiophiles like?"

Register to win a pair of Meze 99 Classics Headphones ($309.00 Retail Value) we are giving away.

According to the company:

"What is it that discards the superfluous, the gimmicky, the flashy, the questionable, the overly fragile, the misplaced? The obvious answer would be time. And this is also the riddle of good design: very few objects achieve such a rarefied consistency of qualities. This is our aim with the Meze 99 Classics, the anti-fragility of a classic, with a sound on par with the design. Pure, natural sound in a timeless body."
