It would be an understatement to say that in 2001, when Nordost introduced their original Valhalla cables, they were a revelation for me. Their focus and resolution of detail were like nothing I'd ever heard, and revealed in recorded performances a startling energy and realism. Throw in their seemingly absolute transparency, and similarly unique levels of spatial and temporal precision, and the Valhallas established a new standard of sound quality in audio cables. Although their tonal balance was cool, as I reported in my first review of them in the November 2001 issue, they were the only game in town in terms of reproducing the feel of a live performance. I immediately adopted them as a reference cable, and they remain a reference for me today.

Life is too short to put up with poor-sounding headphones, I mused the other morning, during my 60-minute commute on the NYC subway. All around me, straphangers gripped smartphones and listened to multicolored Beats, noise-canceling Boses, white Apple earbuds, and, only rarely, Sennheisers and Grados.

Stereophile hasn't reviewed a PS Audio power regenerator since February 2009, when Robert Deutsch tried the company's then-flagship, the Power Plant Premier ($2195). But earlier this year, as I prepared to write my review of PS Audio's NuWave DSD DAC (published in the May 2016 issue), a perfect opportunity to revisit the line came about: I read, in the owner's manual for the PSA DAC, that "power conditioners and the quality of the AC power can make a significant difference in sound quality." Eager to help the NuWave DSD put its best foot forward, I asked PS Audio to assist me in dealing with my AC power, which is marginal here in crowded New York City. They sent me their PerfectWave P10 Power Plant AC Regenerator ($4999)—and John Atkinson asked me to spill some ink on this most recent of the company's clean-power flagships.

I'm sitting on a dark leather sofa, legs crossed, lips pursed, brow furrowed.

Glenn Gould playing Bach's Goldberg Variations can be faintly heard through a tape recorder in another room. To be more specific, a Realistic CTR-68 Model 14-808B.
