Headphones be offering a number of benefits over speaker programs. In all probability most significantly, they take away the acoustic results of the room, offering a extra constant and predictable listening enjoy. Because of this, headphones proceed to encourage a thriving hobbyist neighborhood.
Denon has been making very talked-about headphones for greater than 50 years, and the AH-D9200 is the corporate’s newest flagship style. I reviewed it the usage of Denon’s PMA-60 two-channel built-in amplifier, a combo that makes gorgeous track in combination.
The AH-D9200 is a circumaural (over-ear), closed-back design hand made with top rate fabrics. For instance, the outer casing of each and every earcup is constructed from bamboo, which is alleged to have herbal acoustic houses that very much cut back undesirable resonances and advertise a wealthy, heat tone. As well as, the memory-foam earpads are clad in engineered leather-based for optimum convenience over lengthy listening periods.
A diecast-aluminum hanger supplies strong reinforce and versatility, permitting the earcups to transport freely round two axes for optimum convenience on all kinds of head dimensions and shapes. Convenience may be enhanced via the scarf, which is wrapped in authentic leather-based. However regardless of the usage of such high-end fabrics, the AH-D9200 weighs most effective 375 grams (13.23 oz).
Every earcup properties a 50mm free-edge diaphragm constructed from nanofiber fabrics selected for tension and occasional mass. The diaphragm is fastened in a vibration-reducing engineered-resin baffle with a comfortable encompass subject matter that makes it more uncomplicated to transport in line with the track sign with out flexing or distorting. This design is alleged to cancel out resonances within the diaphragm.
With a specified impedance of 24 ohms and a sensitivity of 105dB/mW, the frequency reaction extends from 5Hz to 56kHz with a most energy dealing with of 1800mW. The neodymium magnet boasts an enormous magnetic box energy of greater than 1 tesla, which is alleged to pressure the diaphragm with decrease distortion and decreased vibration. To place this in standpoint, maximum scientific MRI machines have a magnetic box energy of one.five teslas, whilst Earth’s magnetic box is within the vary of 25 to 65 microteslas on the floor.
The AH-D9200 comes with two removable OFC (oxygen-free copper) cables, either one of which hook up with the 2 earcups with Three.5mm plugs. The copper wires within the Three-meter cable are silver-coated for upper conductivity, and the cable terminates with a 6.3mm (1/Four-inch) plug for a house stereo machine. The wires within the 1.3m cable aren’t silver-coated, and it terminates with a three.5mm plug for moveable gadgets. The shorter cable additionally features a 1/Four-inch adapter.
The incorporated garage case and cleansing material assist stay the headphones secure and pristine. Sadly, it’s slightly flimsy cardboard. I might be expecting a extra considerable case at this worth.
To pressure the AH-D9200, I used Denon’s PMA-60 two-channel built-in amplifier ($599), even though many different amps would paintings neatly with those headphones. The PMA-60 features a devoted headphone-amp circuit that includes a high-speed, low-distortion, wideband op amp paired with an absolutely discrete ultimate output degree. It even gives an adjustable headphone-amp acquire keep watch over with low, medium, and excessive settings. This keep watch over defaults to medium; the excessive environment presented slightly of hiss, so I left it at medium.
For many of my listening, I performed DVD-Audio and SACD discs on an Oppo UDP-203 common participant. The participant’s optical and coax digital-audio outputs downsample high-resolution audio, so I used the left and proper analog outputs, connecting them to the amp’s aux enter with a 1-meter AudioQuest Emerald stereo cable with RCA plugs on each ends.
My favourite high-res audio recordings come from AIX Information, which releases its titles on DVD-Audio and Blu-ray discs with 2-channel and five.1-channel mixes and a PCM decision of 96kHz/24 bits. I began with the 2-channel mixture of Bach’s Brandenburg Concerto No. five in D Main, First Motion: Allegro, as carried out via the George Enescu Philharmonic Orchestra beneath the path of Cristian Mandeal. The sound was once beautiful—wealthy, complete, and open. Every solo device and phase of the orchestra was once obviously rendered, permitting me to listen to deep into the combo.
Subsequent, I listened to a number of tracks from an AIX demo disc referred to as A Top-Solution Audio Enjoy, which contains all kinds of genres. Sticking with classical for the instant, I looked at Chopin’s Nocturne in D Flat primary as carried out via Roberto Prosseda at the album Chopin: Decided on Works. The solo piano was once rendered fantastically; it sounded exceptionally blank all the way through the frequency vary with very good dynamic vary.
For classical vocals, I listened to “Now could be the Month of Maying” from the album Voices Unbound, via Zephyr, a blended a cappella choir. The voices all sounded solely herbal, and it was once simple to listen to each and every voice within the ensemble.
Within the people realm, I performed “Mosaic” from Laurence Juber’s album Guitar Noir and “Ocean” from Jonathan McEuen’s One Step Forward. In each instances, the acoustic guitar and acoustic bass sounded superb, very wealthy and luxurious with none trace of congestion. Likewise, Jonathan McEuen’s vocal sound was once utterly herbal.
Turning to jazz, I looked at “Yo Move Jo Po” from the album Peculiar Males In via the Emil Richards & Joe Porcaro Large Band. I’ve performed in numerous large bands, and the sound of this recording at the AH-D9200 is no doubt proper. I may listen each and every phase obviously, and the solos had been large blank and proper up entrance the place they must be. The similar was once true with “The Very Considered You” as sung via New york Switch alum Cheryl Bentyne on her album Amongst Buddies. The sound of her gorgeous voice was once very intimate, and the piano, guitar, acoustic bass, and drums supported her in simply the correct share.
Along with DVD-Audio, I listened to a couple tracks on SACD discs, which provide a distinct form of high-resolution audio. As a substitute of PCM (pulse code modulation) at 96kHz and 24 bits consistent with pattern, they use a scheme referred to as DSD (Direct Movement Virtual), which makes use of PWM (pulse-width modulation) with 1-bit decision at a lot upper sampling charges, beginning at 2.8MHz. As a result of some SACDs don’t have 2-channel mixes along side five.1 mixes, I set the Oppo participant to output 2-channel on this case.
I began this spherical of listening with “Summer season Fling” from Spyro Gyra’s The Deep Finish. The sound was once superb, very wealthy and attractive. The electrical bass was once impressively deep, and the keyboards, guitar, drums, percussion, and soprano sax had been all large blank and whole.
Likewise, I in reality loved being attentive to O Fortuna from Carl Orff’s Carmina Burana as carried out via the Atlanta Symphony Orchestra and Refrain beneath the path of Donald Runnicles. That is the well-known section that’s utilized in numerous film trailers; it’s most commonly loud however with a couple of comfortable spots. The whole thing sounded very blank and clean; I may simply listen all of the instrumental sections and choral voices, and the bass-drum hits and brass on the finish had been particularly spectacular.
The PMA-60 supplies the power to circulate audio by the use of Bluetooth, so I paired it with my iPhone XS and performed a few tracks from my iTunes library. In the beginning, the extent was once a lot not up to it have been from the Oppo participant, however I found out that the telephone’s quantity environment was once slightly low via default for some explanation why. After turning it up, the extent was once lots loud sufficient.
“Glamour Career” from Steely Dan’s Gaucho sounded nice, even though slightly brighter and extra brittle than DVD-Audio and SACD. The similar was once true of Percy Grainger’s Irish Track from County Derry from the album Grainger: A Lincolnshire Posy via the London Wind Ensemble beneath the path of Denis Wick. This piece has a large dynamic vary, and it sounded fantastic in any respect ranges, with each and every instrumental phase obviously delineated.
The Denon AH-D9200 is the epitome of a flagship audio product. It sounds superb, with deep bass, open midrange, and super-clear highs. If truth be told, the entirety I heard sounded utterly herbal, and I may simply listen deep into the combo.
Additionally, it’s extraordinarily neatly made. As I located it on my head, it felt very strong and considerable, but additionally light-weight, most likely due partially to the earcups’ bamboo casing. And the earpads and headscarf had been extraordinarily at ease, permitting me to concentrate for hours with out pinching or undue power. (After some time, I began to sweat slightly beneath the earpads, however my pores and skin is reasonably energetic in that means; you could no longer have the similar drawback.) My most effective criticism here’s that the incorporated cardboard garage case is simply too flimsy to in reality give protection to the headphone.
At $1,599, the AH-D9200 isn’t for everybody. However for individuals who can find the money for it, Denon’s flagship headphone is definitely well worth the funding, bringing musical nirvana in your ears.
