Reference-anchored coverage of headphones, speakers, DACs, amplifiers, and sources. Long listening, head-to-head comparisons against the category benchmark, and buying guides built from real verdicts. Zero sponsored takes.
HIFIMAN HE1000 Stealth Review: Flagship Planar at a Lower Price
A years-old HIFIMAN flagship, cheaper than ever: Stealth Magnets, a nanometer diaphragm, a wide open soundstage, and a fun, bright tuning - mind the treble peaks and the large fit.
Excellent comfort despite 458g - the wide suspension band spreads the weight
The newest headphones, DACs, amplifiers, speakers, and sources tested on the chain. Each piece earned its score through weeks of comparative listening against the category reference list, with no first-impressions takes.
FIFINE K688 Review: The Mic With the Interface Inside
A dynamic broadcast microphone with both XLR and USB-C outputs, so the audio interface is already inside it: cardioid rejection, 130 dB max SPL, on-body gain and mute.
Synergistic Research Network Router UEF Review: Does a $3,000 Router Improve Sound?
A wired-only audiophile router with a linear power supply, EM cell, ULF generator and carbon fiber voicing. In my system it lowered the noise floor on everything I stream.
Ortvik Parametric Tower Review: Absorber and Diffuser in One
A freestanding acoustic tower that scatters and absorbs at the same time - handmade Czech oak over a recycled PET felt core, placed wherever the room needs it.
HIFIMAN HE1000se Review: The Flagship Built to Sound True
An ex-$3,500 flagship, now $1,700: nanometer diaphragm, Stealth Magnets, a holographic soundstage, and state-of-the-art detail - bright, honest, merciless with bad sources.
Douk Audio U2 Pro Review: Does a $70 DDC Reclocker Actually Work?
A $70 XMOS XU316 DDC reclocker (USB-C in; TOSLINK, coax, I²S out). Tighter timing and a fuller, more detailed sound - at the cost of some air and openness.
HIFIMAN Serenade Review: One Box to Replace Your DAC, Amp, and Streamer
HIFIMAN's all-in-one R2R DAC, discrete Class A amp, and hi-res network streamer in one 3kg box - lush, musical, and powerful enough to drive almost anything.
Four rules, applied to every review without exception. A 9.2 here means the same thing in 2030.
No sponsored verdicts
Brands have zero editorial input. Pre-publication review is never granted. A negative review ships even if the manufacturer pulls their ad spend.
Long listening, every time
Two-week minimum on the chain, multiple sources, multiple genres. No first-impressions reviews. No demo-room verdicts.
Reference-anchored scoring
Every piece is compared head-to-head against a published reference list in its category. A 9.0 on a headphone carries the same weight as a 9.0 on a DAC.
Disclosure first
Loaner units are flagged in every review header. We never accept payment to influence a verdict - and we publish it if a brand tries.
Seven review hubs covering headphones, speakers, DACs, headphone amps, speaker amps, sources, and the accessories that connect them. Each hub is a focused review archive. Every piece is compared head-to-head against the category reference list, scored on the same 0 to 10 scale with the same listening protocol, so a 9.0 in one category carries the same weight as a 9.0 in any other.
Curated "best of" lists where every pick is one of our scored reviews - ranked by what actually sounds best on the chain, never by who paid. No "top 10" filler.
Same chain, same listener, same reference recordings - so the score gap between two pieces is real comparative difference, not calibration drift. The closest, most cross-shopped matchups in the catalogue.
Calculators, blind tests, and analyzers that usually cost money or need an install. Every one runs in your browser - no signup, no upload, no tracking - and is built from the same engineering that backs the reviews.
Six in-house pieces, each one a previously published review you can read in full, form the fixed reference chain every piece of incoming gear is volume-matched against. Swap one component, hold the rest constant; that is how a single 9.0 carries the same weight across DAC, amp, headphone, and speaker categories.
Planar magnetic, open-back - Stealth Magnets, neodymium drive, and a nanometer diaphragm. 9.3/10 - the tonality and resolution anchor for every headphone comparison.
Mains conditioning. 9.2/10 - the only Reference-tier accessory in the catalogue; the noise floor every review sits on.
Standards we cite

How scoring works, what the verdicts mean, and the editorial rules behind every audio review.
How does The Audio Stuff score audio gear?
Every review carries a single score from 0 to 10 plus a one-word verdict, and each verdict owns a score band: Reference 9.0-10, Highly Recommended 8.2-9.4, Recommended 7.0-8.4, Mixed 5.5-7.4, Pass 0-6.4. Adjacent bands overlap on purpose - that overlap is the judgment zone where price, competition and reliability decide the tier - but a verdict is never two tiers away from its number, and a review that breaks the rule fails the build. Scores are anchored to a published reference list per category, so a 9.0 on a headphone carries the same weight as a 9.0 on a DAC, an integrated amp, or a pair of bookshelf speakers. The reference list updates as new gear earns its place; older scores can move when a new benchmark arrives.
Are any audio reviews paid for or sponsored?
No - never. Brands have zero editorial input on reviews. Pre-publication review of drafts is never granted. We never accept payment to influence a verdict, and if a manufacturer pulls advertising over a negative review, that gets disclosed in the piece too. The wallet of the reader is the only one we are looking out for.
Do you buy gear yourself or accept manufacturer loaners?
Both, and it is always disclosed. Most flagship and reference-tier gear is loaned by manufacturers or distributors - those loaners are flagged at the top of every review. Mid-tier and budget pieces are usually purchased outright, often used. Either way the review still gets written, the piece still earns the score it deserves, and the unit goes back when the loan window closes.
How long does each audio review take to complete?
Two weeks minimum on the chain in real daily use - typically four to eight weeks for flagship gear, sometimes longer. Reviews are compared against multiple reference pieces, across multiple sources, in multiple genres, before a score is committed. There are no first-impressions reviews and no demo-room verdicts.
Can I submit audio gear for review?
Yes. Email contact@theaudiostuff.com with the unit name, asking price, return window, and a short pitch on why it deserves coverage. We will respond before anything ships. There is no guarantee of a positive verdict, and we do not commit to a publishing date until the listening period is complete.
What does 'Reference' mean in the verdict scale?
Reference is the highest verdict on the scale. It means the piece is a benchmark in its category - the unit that other gear in the same class is judged against. Reference is not the same as best for everyone (price, taste, system context all matter), but it is the unequivocal best at what it sets out to do, with no meaningful flaws holding it back at its price tier.
What audio gear brands does The Audio Stuff cover?
We review gear from any brand making noteworthy products - established names like Sennheiser, Focal, KEF, HIFIMAN, and SMSL, alongside specialist manufacturers like Ferrum, Holo Audio, Eversolo, Schiit, Topping, and Audeze. Category, merit, and reader requests drive the review queue. Brand relationships do not.
Do reviews use measurements or just listening tests?
Both, in that order of weight. Listening is always primary - over weeks, on multiple chains, against published references. Measurements (frequency response, distortion, output impedance, jitter, sensitivity) are added when they reveal something audible or contradict the marketing claims. We do not chase graphs over what the gear actually sounds like in a real room.
How is audio gear compared head-to-head in a review?
Two ways. Same chain, different gear - swap the DAC, swap the amp, swap the headphones - same source, same recording, same volume-matched level. And A/B comparisons against the published reference list at the same price tier. Every review names the comparison units explicitly so the verdict is reproducible if you have one of those references on hand.
