This is a singer who has rock ‘n’ roll in his veins, and the live performances of rock standards like ‘Susie Q’ and an early cover of The Beatles’ ‘I’ll Cry Instead’ were delivered with such impact that the surface noise disappeared like tinnitus in a hurricane. There was something about the playback that enabled you to listen through the detritus. In addition to the sounds of the venue, Rivers’ distinctive vocals, with his mix of textures and a hint of nasality, were as perfectly reproduced as I have heard… and I am a Rivers devotee.
Toying with a worn-out LP is hardly an ideal way to assess a piece of equipment, but it does educe the belief that a fine system can work wonders with a less-than-wonderful recording, or in this case an LP in not-so-pristine condition. With the sonic spectacular that is Hall & Oates’ H2O [RCA RCALP6056], a mint original, the bottom end heard on ‘Maneater’ made me question what was alleged to be the logical sonic sacrifice of the Air Force IV versus the Air Force III. Surely the overall mass of the III, the vastly heavier platter, would lead to greater impact and weight? At no point did it sound like the IV was losing anything to the beefier III.

HIFIMAN Arya Wi-Fi Streaming Media Planar Magnetic Headphone $1449 Review
September 10, 2026 § Leave a comment
When I think of HIFIMAN, lately I’ve also been thinking about Dr. Fang Bian and his visionary push for his company. I remember him once saying that he doesn’t like to simply repeat success, but to keep pushing into new territory. He has many “firsts” to his name, including the first “First True High-Fidelity Portable Music Player” that HIFIMAN brought out in 2009 called the “HIFIMAN HM-801”. That was followed by the first planar magnetic headphones designed for the mass consumer market, the “HE-5” in 2009, and the world’s first R2R True Wireless Earphones, the “Svanar Wireless”, in 2023. This was followed by the “Unveiled” open-back technology that removed the outer protective grill from the headphones. This started with the flagship Susvara, which I reviewed in Oct. of 2024, and has now been incorporated in several of the HIFIMAN models. And now, in 2026, we have the release of the Arya Wi-Fi and the HE1000 Wi-Fi, another bold first in the headphone world.
Though this world’s first Wi-Fi planar magnetic headphone series has had some network set-up issues (at least for me) and is awaiting an iOS app as of this writing, the headphones themselves are stellar. Not stellar because they are the first Wi-Fi headphones, but simply stellar. They have the quality of “soul” that I love to find in a headphone. It is an intangible quality that makes me stop analyzing for a review and simply get lost in the music. Considering the amount of hi-tech packed into these headphones, it may be odd to say they have soul, but for me, they do.

Marten Parker Duo Diamond Edition $35,000 Review

Unusually for such revealing and analytical performers, these Marten speakers won’t go out of their way to highlight those flaws. You can hear the shortcomings easily, of course, but they remain in proportion, and the good parts of the recording will still shine.
However, feed these speakers a diet of great recordings – classics such as Miles Davis’ Kind Of Blue or Take Five by the Dave Brubeck Quartet, for example – and they will turn in a performance full of subtlety, dynamics and cohesion that’s almost eerily convincing.
That the Marten Parker Duo Diamond Edition are capable of a high level of resolution should not be a surprise. Such qualities should be a given at this level. However, what sets them apart from most rivals is the degree to which they step beyond the mechanics of hi-fi – you know, a cone moving backs and forward, crossover components and enclosure resonances – to put the music front and centre.
These speakers sound impressively natural regardless of whether we are talking about rendering instrumental textures in classic jazz recordings or the nuances of Billie Eilish and Khalid’s vocals on the wonderful song, Lovely.

Onkyo A-50 Network Integrated Amplifier$1,599 Review

With its $1,599 MSRP, the Onkyo A-50 Network Integrated Amplifier is essentially a streaming computer built around a very good integrated amplifier with a built-in DAC and phono stage. You can build a very feature-rich system by simply adding a pair of speakers and streaming all of your music to it, and you can add a turntable or CD player to it later if you’re into physical media.


Dan D’Agostino Momentum Z Mono Amplifier $125,000 a pair Review

Since my Alexx V arrived, very few upgrades have moved the entire system this far forward. The Dan D’Agostino Momentum Z is one of them. This is not a small refinement to the Momentum formula. To my ears, it is a step function. I am hearing things from the Alexx V at whisper quiet levels and at the other end of the volume knob that I simply had not heard before.
What makes this even more interesting is where D’Agostino goes from here. Out of the gate, the C2Z and Momentum Z combination felt like it was nipping at the heels of the Relentless systems I have heard. Dan and the team have already moved the goalposts again, taking the Z technology into the new Relentless Z Preamplifier, Relentless 800Z, and Relentless Epic 1600Z. That tells me the Momentum Z was not just another product cycle. It was the beginning of a new architecture for the company.
I also cannot stress enough how much I love that they managed all of this while staying true to the original Momentum form factor. The Z is heavier, more complicated, and much more ambitious inside, yet it still looks and lives like a Momentum. It fits on a normal rack shelf. At this level, that matters more than it might sound.
If you own an S250 or M400 and can swing the cost, the Dan D’Agostino Momentum Z gets my highest recommendation. In fact, if I were choosing between this and chasing the next source upgrade, I would do the amplifier first. The Z lets you hear more of everything already in front of it. I am hearing things from my Alexx V, at extremely low and extremely high volumes, that I simply have not heard before.



Sendy Audio Kylin $1,499 Review

So, I had to take my most insensitive headphones to perform the listening testing. The Sennheiser HD6XX was also fine, as it’s high impedance and the noise couldn’t come through. And the thing is, once you have the right headphones connected, the Sendy Kylin is pretty excellent. Maybe they only used their own planars to test it and nothing easier to drive?
So, with my heavier loads, the Sendy Kylin exhibited a very mature and sophisticated sound signature. Not too warm and not cold in the least, despite using an ESS chip. Together with the Questyle Sigma Pro, it’s one of the more organic-sounding implementations of an ESS converter that I’ve heard. Long-term listenability is great, provided you have the right headphones.
In terms of technicalities, the Sendy Kylin is also one of the more impressive all-in-ones I’ve heard. There’s a very believable transmission of timbre and overall recording venue ambiance. I had to use my Moondrop Skyland to really explore the depths of it all. Macro dynamics here are stronger than minute shifts, likely because of the relatively high noise floor.

I am not going to say it was as night-and-day as comparing tubes with transistors, but careful, intense and even frustrating listening allowed me to differentiate between the two, the vast cost disparity notwithstanding. That in itself makes all of this moot. But I was able to tell which was which thanks to my old faves, the J. Geils Band.
‘Did You No Wrong’ from Ladies Invited [Atlantic SD 7286] features each of the band’s members displaying virtuoso talents on guitar, harmonica, drums and assorted keyboards. Both decks allowed the listener to zoom in on each, or simply sit back and savour the experience. Where the two differed was in presentation. The Air Force III was more revealing, more analytical, with the kind of grip and command which places great demands on the rest of the system.
