Find the right gear, not the highest score.

The best product on the list is rarely the right one for your ears, your room or your budget. Start from where you are: a product you already have in mind, two you are torn between, or none.

Henry Audio DA 256 Review: A €1,600 Open-Source DAC That Skips XLR on Purpose

Twenty years of one engineer's work in a €1,600 box: a published schematic and firmware, reclocked coax and optical, RCA only, PCM to 24-bit/192 kHz, and every omission deliberate.

Watch out for: No XLR outputs at all

FIFINE K688 Review: A $69 XLR and USB Broadcast Mic

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: An Acoustic Panel and Diffuser

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.

Watch out for: No bass absorption

How every review is tested and scored.

Four rules, applied to every review without exception. The median score across all 70 reviews is 8.1, and nothing has scored above 9.3.

  1. No sponsored verdicts

    Brands have zero editorial input. Pre-publication review is never granted. The site carries no advertising and no affiliate links, so a negative review ships with nothing for a brand to withdraw.

  2. Long listening, every time

    Two-week minimum on the chain, multiple sources, multiple genres. No first-impressions reviews. No demo-room verdicts.

  3. One rubric, every change dated

    Every score is one writer's judgement, weighed on the same five published axes and set against the gear its category is compared on. Scores compare within a category, and a score that changes keeps the old one on the review, with the date and the reason.

  4. Disclosure first

    Most flagship units are lent by their maker or distributor and go back after the review, and a loan never buys a verdict. We never accept payment to influence one - and we publish it if a brand tries.

The test chain

A product under review is swapped into the same fixed chain, with everything else held constant, and heard sighted with the volume set by ear. Each piece is a published review.

Who does the listening

Every review is signed by the writer who tested the gear, and each writer's page lists everything they have reviewed and the verdicts they have given.

  • Jakub Charkiewicz, founder and lead reviewer, has written 66 reviews and 12 buying guides since .

  • Bastien Beauchamp, reviewer, has written 4 reviews since .

Common questions about our reviews.

How scoring works, what the verdicts mean and which gear we cover.

More questions about how we work

  1. 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 no other tier shares: Reference 9.2-10.0, Highly Recommended 8.2-9.1, Recommended 7.0-8.1, Mixed 5.5-6.9, Pass 0.0-5.4. The bands do not overlap, so a score names one tier. The single exception is a score exactly on a tier's floor (9.2, 8.2, 7.0 or 5.5): that makes a product eligible for the tier, and the verdict may hold it one tier lower where price, competition or reliability argue against the higher one. Our publishing system will not let a review go live with a verdict its score does not allow. A score is one writer's overall judgement after weeks of listening, set against the reference for its category at a similar price, with the five published weights of the rubric (Sound 30%, Technical performance 25%, Build & comfort 15%, System fit 15% and Value 15%) as the guide; it is not computed from them. Scores compare within a category, and the verdict bands are this site's own. A published score is not recomputed when a price moves or a newer product arrives, and a score the editor changes keeps the earlier one on the review, with the date and the reason.

  2. What does 'Reference' mean in the verdict scale?

    Reference is the top verdict, for scores of 9.2 and up: a product that sets the standard in its class, and rare by design. It does not mean the product suits everyone - price, taste and the rest of your system still decide that. It is also a different thing from the test chain, the gear every review is compared on: a piece is in the chain because it stays the same from one review to the next, and three of its six pieces score below 9.2.

  3. What audio gear brands does The Audio Stuff cover?

    Gear from 33 brands so far, most of all HIFIMAN, SMSL, Sivga, Taga Harmony, Denafrips, Kiwi Ears, Melodika and Monosaudio; the other 25 are in the review catalogue, searchable by name. Category, merit and reader requests decide what gets reviewed next; brand relationships do not.

  4. Do reviews use measurements or just listening tests?

    Listening. Every review is sighted listening over weeks on the fixed chain its category is compared on, with levels set by ear, and none is a blind test. Nothing is measured in-house: the impedance, sensitivity, power and noise figures a review quotes are the maker's published specifications, corrected on the review when the maker's own page says otherwise. That puts the large differences a review describes, such as a headphone's tonal balance, on firmer ground than the small ones, such as what a cable changes. The how-we-test page sets out what a score can and cannot tell you.
