Overview
The Audio Stuff is an independent online publication dedicated to honest, reference-anchored reviews of audiophile and hi-fi audio gear. Founded and run by Jakub Charkiewicz, the site covers headphones, speakers, DACs, amplifiers, sources, and accessories. With over 62 published reviews, each piece of gear is scored on a 0 to 10 scale and compared head-to-head against a published reference list in its category. The site also offers 16 free browser-based audio tools, buying guides, and comparison pages. The Audio Stuff operates with a strict editorial policy: no sponsored verdicts, no pre-publication review by manufacturers, and full disclosure of loaner units. The reference chain includes six in-house components, each previously reviewed, ensuring consistent testing conditions across all reviews.
Services & Expertise
The Audio Stuff provides a comprehensive suite of services for audiophiles and hi-fi enthusiasts:
-
Headphone Reviews: In-depth evaluations of open-back, closed-back, planar magnetic, dynamic, and in-ear monitors (IEMs). Each review includes a score, verdict tier (Reference, Highly Recommended, Recommended, Mixed, or Pass), and detailed analysis of tonality, technicalities, build, system fit, and value. The site currently features 28 headphone reviews.
-
Speaker Reviews: Coverage of bookshelf, floorstanding, active, passive, and studio monitor speakers. Six reviews are available, each anchored to the reference loudspeaker (Triangle Australe EZ) and measured using the ANSI/CTA-2034-B Spinorama framework.
-
DAC Reviews: Analysis of desktop, portable, R-2R ladder, and delta-sigma DACs. Six reviews are published, with the Denafrips Enyo 15th Anniversary serving as the reference DAC. Measurements follow AES standards for SNR, THD+N, and IMD.
-
Amplifier Reviews: Separate categories for headphone amps (4 reviews) and speaker amps & preamps (3 reviews). The HIFIMAN Serenade is the reference headphone amplifier. All comparisons are volume-matched to ITU-R BS.1770-4 LUFS standards.
-
Source & Accessory Reviews: Coverage of network streamers, all-in-ones, transports, turntables (4 reviews), and accessories like cables, stands, room treatment, and tweaks (11 reviews). The Denafrips Hermes 12th Anniversary is the reference digital source.
-
Buying Guides: Six curated "best of" lists that rank scored picks by actual listening performance. Categories include best DAC under $2,000, best headphone amplifiers, best IEMs, best open-back headphones, best planar magnetic headphones, and best reference-grade audio gear.
-
Comparison Pages: 33 head-to-head comparisons between closely matched products, tested on the same chain with the same recordings. Each comparison quantifies the score gap and explains the real-world differences.
-
Free Audio Tools: 16 browser-based tools including a headphone power calculator, ABX blind test, hi-res audio fraud detector, EQ simulator, room mode calculator, and a "Help Me Choose" finder that generates ranked shortlists from the review database.
-
YouTube Channel: Long-form video reviews, listening sessions, A/B comparisons, and teardowns. New videos are published most weeks, complementing the written reviews.
How They Work
The Audio Stuff follows a rigorous, transparent review process. Every piece of gear is tested on a fixed reference chain consisting of six in-house components: the Denafrips Enyo 15th Anniversary DAC, HIFIMAN Serenade headphone amplifier, HIFIMAN Arya Organic headphones, Triangle Australe EZ speakers, Denafrips Hermes 12th Anniversary digital source, and Synergistic Research PowerCell 14 power conditioner. Each review begins with a minimum two-week listening period, often extending to four to eight weeks for flagship gear. The reviewer listens across multiple sources, multiple genres, and compares the unit head-to-head against the published reference list for its category and price tier. All A/B comparisons are volume-matched to the ITU-R BS.1770-4 standard, not by ear. Scores are built from five weighted axes: tonality (30%), technicalities (25%), build & ergonomics (15%), system fit (15%), and value (15%). The weighted sum is rounded to one decimal and mapped to one of five verdicts. Measurements (frequency response, distortion, output impedance, jitter, sensitivity) are added when they reveal something audible or contradict marketing claims. The entire process is documented on the site, including the editorial promise of no sponsored verdicts and full disclosure of loaner units.
