JMF Audio HQS 7001

MONOBLOCK POWER AMPLIFIER

- JASON VICTOR SERINUS

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
