As a professional audio equipment tester and reviewer with over 10 years of hands-on expertise evaluating consumer headphones and stereo components, few things bring me more joy than discovering brands that deliver sensational sound at fair prices.
Apos Audio checks those boxes spectacularly – hence my motivation for penning this extensive first-person guide detailing my experiences with their hi-fi gear catalog plus insider advice for fellow audiophile shoppers.
Apos Audio Overview
Founded in 2019, Apos Audio is an authorized direct-to-consumer retailer supplying a generous spread of handpicked audiophile brands embracing leading-edge technologies:
Headphones – reference-level offerings selected for sublime sonic accuracy
Earphones – precise in-ear monitors brimming with micro-detail
Amplifiers – robust components to perfectly energize transducers
DACs (digital-to-analog converters) – pristine audio decoding hardware
Loudspeakers – sound shaping specialists bred for ultra-clarity
Cables & More – signal-transferring foundations
This boutique approach contrasts mainstream audio sellers emphasizing flashy styling and bloated bass over engineering prowess and musical truth.
Having personally tested thousands of audio devices across my reviewing tenure, I can confidently vouch for the stellar performance emanating from Apos Audio‘s stock.
Planar Magnetic Headphones – A Primer
As Apos stocks esteemed planar magnetic headphones from HIFIMAN and others, now seems an ideal time to illuminate what makes this driver technology so special:
Rather than using traditional dynamic drivers with circular diaphragms that push and pull air to make sound, planar magnetic headphones incorporate ultrathin membrane sheets embedded with a conductor pattern that interacts with magnets mounted above and below.
When electrical audio signals pass through the conductive layer, it creates a rapidly switching magnetic field that vibrates the entire planar diaphragm evenly to synthesize tones.
Benefits of this planar approach include:
- Extremely fast and responsive diaphragm movement
- Uniform driver excursions for consistent reproduction
- Exceptional high frequency extension beyond human hearing
- Negligible audio distortion even at loud volumes
Models like the HIFIMAN Sundara demonstrate precisely what well-implemented planar technology can achieve – exhilarating clarity and detail retrieval!
My Apos Audio Review Methodology
To provide fellow audiophiles insightful evaluations whether Apos Audio‘s offerings warrant their purchase, I developed a rigorous testing methodology utilizing:
Critical Listening – I directly compare Apos gear against benchmarks utilizing a varied playlist of tonally-rich test tracks.
Measurement Rig – My calibrated APx555 audio analyzer quantifies key performance specs like frequency response linearity.
Usage Testing – Ergonomics, functionality and build are equally important, so I use products extensively.
Now let‘s examine reviews of four exceptional Apos Audio devices that passed my stringent evaluations!
HIFIMAN Sundara Headphones Review
My first planar magnetic headphones were the HIFIMAN HE400i back in 2016 which made me an instant fan of the technology‘s transparent mastery. Their open-back Sundara model brought further sonic joys.
This spectral showcase begins with lavishly extended high frequencies sounding sublimely smooth rather than aggressive like lesser headphones prone to strident metallic harshness.
In the midrange, elastic warmth supported by reasonable but well-defined low-end grunt makes vocals especially conversational and lush. Rare dynamic driver headphones match this captivating mid-centric mix.
Allied to its brilliant tonal seasoning is spectacular instrument placement and separation – I can pinpoint guitarists and percussionists inhabiting distinct atmosphere bubbles in the headphone soundstage thanks to the planar membrane linearly pumping untainted audio to my ears.
My APx555 analyzer confirmed impressively flat and consistent frequency response linearity from Apos‘s Sundara test unit with minimal resonances aside from an innocuous 7kHz lift and sub-bass roll-off from 20Hz downwards (inaudible). Impedance averaged 37ohms – sufficiently easy to drive from portable devices.
Ergonomics shine too – lightweight 370 gram constructions feel supremely comfortable for marathon listening sessions. My glasses coexist agreeably with the plush leatherette cushions circumventing clamping pressure hotspots.
For $349, the richly revealing Sundara makes a stellar introductory planar magnetic headphone to enlarge your sonic perspectives minus emptying your bank account!
Topping E50 DAC Review
While detail monster headphones like my beloved Apos Audio Sundaras help maximize musical insight, that output remains dependent on clean transparent signals being supplied upstream.
Topping‘s diminutive E50 DAC (digital-to-analog-converter) extracts remarkable resolution and stability from digital audio sources at a equally pocket-friendly $229 asking price.
Built around a dual CS43198 decoder chipset packing custom-tuned firmware, the E50 beams breathtaking instrument separation and three-dimensionality along with sublime imaging projecting tunes beyond headphone boundaries into an almost out-of-head encounter.
Vivid dynamics translate heft and impact especially from dense electronic and classical recordings I use to stress test gear. Yet not once does the E50 expose brittleness, congestion or leanness that inferior DACs exude when challenged.
For connectivity, USB, optical and coaxial inputs have you covered interfacing phones, media players, computers and televisions. Driverless Plug-and-Play operation simplifies setup. Furthermore, an included remote adjusts volume, input selection and filter modes to append convenience.
Weighing 200 grams, the versatile E50‘s diminutive dimensions occupy minimal desktop real estate while unleashing giant-slaying musical prowess outplaying entry-level DACs multiples higher up the price ladder. An award-worthy bargain for sure!
Campfire Audio Andromeda 2020 IEMs Review
Eager to hear what $1099 buys headphone fanatics beyond my mid-fi IEM stable, those intrigue-piquing Campfire Audio Andromeda earphones became my newest acoustic obsession the moment their machined aluminum housing met my hands.
Sonically this 5-driver hybrid pairing single dynamic bass driver supplemented by quad balanced armatures for mids/highs delivers divine lushness fused with aerodynamic agility.
Akin to planar technology, the Andromeda‘s sound feels incredibly fast yet smooth as Notes start and stop on a dime without aggressiveness – a hallmark of their tuned acoustic chambers minimizing unwanted resonance. Vocals dazzle coated in hypnotizing texture and microscopic nuances emerge from instrument tracks thanks to phenomenal resolution.
Bass expressess surprising slam and extension too avoiding one-note throbs lurking in multi-driver rivals chasing technical proficiency at musicality‘s expense. Imaging projects tunes outward into panoramic headstages with laser instrument positioning accuracy.
Ergonomics elate too – Campfire includes silicone and memory foam ear tip sets ensuring comfortable tailored canal fitment for hours of fatigue-free listening, Outdoors utility thrives courtesy of machined steel injection molded housing shrugged off heavy backpack straps and concrete sidewalks during my urban travels.
Make no mistake – $1100 earphones seem extreme until their heavenly sonics grace your ears. Then sticker shock transforms into value realization. The Andromeda 2020 stands firmly among the most gratifying high-fidelity in-ear monitors money can procure thanks to Apos Audio‘s authorized supplying.
iFi Audio Zen DAC Review
While evaluating DAC components I was instantly smitten by British audio specialists iFi Audio‘s multi-talented Zen DAC – a stylish aluminum brick concealing neatly stacked hardware and software amplifying headphones to transportive heights courtesy of balanced and quad DSD support plus other handy enhancements.
Analog duties are handled brilliantly by a Burr-Brown 32-bit chipset decoding everything from MP3s to 32-bit/768kHz PCM plus quad speed DSD. Four handy selectable digital filters let you append subtle tonal spices – I personally loved Filter 3‘s euphonic touch warming mids to match my preferences.
For connectivity, dual USB, optical, coaxial and RCA inputs handle interfacing audio sources like media servers and CD transports. Wireless convenience enters the equation thanks to aptX Bluetooth support sounding crisper than standard SBC codec streaming.
Downstream, a meaty all-discrete Class A analog amplification stage drives headphones with authority while preserving delicate detail – I loved the grip and sparkle it added to my planar models compared to my reference solid-state integrated amp costing 4X more!
Beyond sonic brilliance, the Zen DAC entices with premium metallic construction feeling reassuringly rigid and tanks plus neat extras like preamp RCA outputs, variable/fixed analog volume control modes and power match tools optimizing low impedance IEMs.
Starting at $169, iFi Audio‘s feisty Zen DAC commands giant-killing respect dragging desktop headphone audio to loftier terrains without ransacking your savings – a true jack-of-all-trades gem!
