JMF Audio HQS 7001
Stereophile
|February 2024
MONOBLOCK POWER AMPLIFIER
For some, it takes the likes of Scheherazade to seduce; for me, simple sound will suffice. But not just any sound. If I'm going to enter into a relationship with an audio component, I want it to last.
I don't know anyone who, having heard the JMF Audio system at AXPONA 2023-the HQS¹ 6002 dual-mono power amplifier ($40,000) and PRS 1.5 dual-mono line stage preamplifier ($36,000) with Harbeth M40.3 XD speakers-did not rave about the sound. In my show report, I credited the system, assembled by Fidelis Distribution and Audio Skies, with delivering "some of the finestsounding music" I heard at the show. "This is the perfect sound for mellow music," I proclaimed. "Bliss."
Only the need to write umpteen show reports in a short span prevented me from saying more. Completely won over and hoping that JMF Audio's amplifiers would sound as good with my Wilson Audio Alexia V loudspeakers as they did with Harbeth 40.3 XDs, this serial reviewer of mono amps immediately asked Michael Vamos of Audio Skies, the US distributor of JMF Audio, if he (I) could review a pair of JMF monoblocks. The $77,000/pair JMF HQS 7001, which, according to their specifications, output 300W into 8 ohms, 500W into 4 ohms, and 850W into 2 ohms, were the best JMF Audio amps Michael could offer at the time.² Given their power and price, they promised a near-ideal comparison with my reference D'Agostino Momentum M400 MXV monoblocks, which cost $79,500/pair and are specified to output 400W into 8 ohms, 800W into 4 ohms, and 1600W into 2 ohms.³

Doing it for themselves—and for us
Women have undeniably become the most dynamic and vital creative force in music today. Without their good energies and ideas, music, which in the digital age has become more background than art, would be much less interesting and inspiring.

15 FOR 50 1975 IN 15 RECORDS
WAS IT SOMETHING IN THE AIR, SOMETHING IN THE WATER? COSMICALLY INSPIRED BY THE STARS AND THE MOON? OR MAYBE THE DEVIL WAS FINALLY CLAIMING HIS OWN AS ROCK MUSIC IN ALL ITS VARIANTS WAS UNASSAILABLY ASCENDENT.

Pablo Records via Granz and Kassem
Way back in my ignorant youth I thought that Pablo Records, the label of jazz producer/promoter legend Norman Granz, was where jazz artists went to fade away, where they were put out to pasture.

Hi-fi for (very) small spaces
For the past few months, I've been getting ready to move. Those of you who've looked for an apartment in New York City know that it may be the single most dismal thing about living here.

The Shanling ET3 CD transport
Costing just $899, Shanling's top-loading ET3 CD transport appears to have been designed by people who recognize the multitude of big and small fails (or lost opportunities) of previous CD transports. In use, the ET3 felt like a distillation of what I've always wanted in a transport: strong, solid, compact, cool-looking, and feels good to use. Everyone knows I like pro-audio cool with no froufrou. This Shanling deck looked so damn smart and felt so good to touch that it kept my mind repeating, \"Yep! That's how a CD transport should be built!\"

CH Precision C10
It takes audacity for a company that already builds one of the finest DACs on the planet, which is already expensive, to set out to build one that's so much better that it warrants an extra digit in the model number and a much higher price tag. But then CH Precision has never lacked audacity.
