Speaker Amps & Preamps A807.8
A $200 Class D integrated amp with Bluetooth, USB-C, optical, coax, RCA and TRS inputs and a one-knob menu, whose sound came surprisingly close to an amp at ten times its price.
DACs DA 2568.2
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.
Microphones & Recording OC168.7
A $449 cardioid condenser built around the CKR6, a ceramic-ring capsule hand-assembled and measured in Vienna: 148 dB max SPL, 14 dB(A) self-noise, one high-pass filter.
Microphones & Recording K6887.2
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.
Accessories Network Router UEF7.8
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.
Accessories Parametric Tower8.5
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.
Headphones HE1000se9.3
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.
Headphones HE1000 Stealth8.5
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.
Digital Sources U2 Pro6.5
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.
Headphone Amps Serenade9.3
HIFIMAN's all-in-one R2R DAC, discrete Class A amp, and hi-res network streamer in one 3.9kg box - lush, musical, and powerful enough to drive almost anything.
Headphones SV021 Pro7.6
A $179 wood-earcup closed-back with a fun, bass-forward sound. A revised driver fixes the original's treble sibilance, though isolation and midrange refinement still lag.
Headphones 105 Silva8.7
A $499 open-back dynamic with hand-polished walnut cups, a custom 50mm carbon fiber-reinforced dome driver, and a warm, fun, easy-to-drive tuning that punches well above its price.
Headphones Belle, Cadenza II, Orchestra II8.1
Three Kiwi Ears IEMs head-to-head - the $30 Belle with a mic, the $50 Cadenza II with KARS 2.0, and the 10-BA $350 Orchestra II flagship. Which is the value pick?
Accessories Woody Queen9.0
Handmade Czech acoustic panels with a luxurious wood frame and PET felt core - true broadband absorption to 100Hz, zero fiberglass, and a 0.94 NRC rating.
Headphones Arya Unveiled9.1
An open-back planar that strips away the outer grill entirely - exposing the driver to deliver dead-silent backgrounds, holographic imaging, and the smoothest Arya treble yet.
Headphones Atheia7.9
A closed-back hybrid headphone pairing a 50mm dynamic driver with a 14.5mm planar - dynamic slam on the bottom, planar speed on top, in a walnut and aluminum chassis.
Headphones Eris6.8
A semi-closed dynamic with 50mm ceramic-metal drivers and a deliberately overwhelming sub-bass tuning - tactile, fun, and tailor-made for EDM, hip-hop, and bass-heavy genres.
Accessories PowerCell 149.2
A 14-outlet flagship power conditioner with seven SRX folded EM cells, ULF+DC biasing, graphene treatment, and a silver matrix ground strap - a tier above any 'power strip'.
DACs ZD37.1
A $150 desktop DAC that punches above its price - swappable op-amps, balanced XLR and RCA, HDMI ARC, Bluetooth aptX HD, a 126 dB SNR, and a clean, slightly bright sound.
Speaker Amps & Preamps Hades 12th9.0
A pure Class A, fully balanced, true discrete preamp with a 60-step relay-based resistor ladder volume control - perfect channel balance, 0.00045% THD, 122dB SNR.
Headphones X18.9
An open-back studio reference headphone with AI-assisted per-unit calibration (±1dB), modular design, real wood cups, and a flat tuning that works for both mixing and music.
Speaker Amps & Preamps AD-1PA+9.0
A 42kg switchable Class A/AB power amplifier paired with a fully balanced preamp - 330W into 8Ω, serious bass control and golden-hued mids.
Microphones & Recording SCT 20008.1
A large-diaphragm tube condenser at $231 with a real 12AX7B tube, nine polar patterns, gold-sputtered diaphragm, and a sound that competes with mics 3-5x the price.
Headphones Anser8.0
A $199 open-back dynamic with real wood cups and a tuning that delivers springy, bouncy mid-bass you won't find on $2,000 headphones - musical, fun, and built to last.
Speakers TAV-607F7.9
A surprisingly capable three-way floor-stander with twin 6.5" woofers, an angled-top low-interference cabinet, and an articulate, energetic sound that punches above its budget.
Headphone Amps EF5008.2
The most affordable HIFIMAN unit to feature their proprietary Himalaya R2R DAC chip - 4.5W per channel balanced, network streaming, and a vertical tower form factor.
Accessories HiFi Tweaks Roundup7.8
Three real tweaks that improve a high-end system without swapping speakers or amps - audiophile network/USB/digital cables, AC power conditioning, and parallel filtering.
Headphones KB026.9
A $39 hybrid IEM combining a 10mm beryllium-plated dynamic driver with a bone conduction driver tuned for sub-bass - V-shaped, punchy, and surprisingly capable.
Headphones Max 17.0
Hi-Res certified wireless over-ears with LDAC, a 20ms ultra-low-latency wireless DJ mode, dual jacks, and 120 hours of battery life - all for €179.
Digital Sources Hermes 12th Anniversary8.9
A serious DDC with OCXO clocking, FIFO reclocking, dual I²S outputs, and two BNC clock inputs - removes the veil between your source and DAC without coloring the sound.
Headphone Amps EF4998.1
A balanced R2R DAC/headphone amp with built-in network streaming for under $300 - warm, musical, and a serious one-box answer to the separates-or-not question.
Accessories PF-1000LPS8.0
A serious 8-outlet power filter with a linear DC/USB supply, 3-tier filtering, audiophile fuses, and a phase detector - real protection and a measurable noise drop.
Speakers TAV-500B v.27.9
Active 6.5-inch bookshelf speakers with built-in Class D amplification, Bluetooth, USB, optical, and a 30Hz bass extension that punches way above their €249 price.
Speakers Australe EZ8.1
French three-way floor-standers with a rear-firing DPS tweeter that 'cheats' a massive soundstage - lively, detailed, and demanding the right partnering gear.
DACs Enyo 15th Anniversary9.1
A $699 true balanced R2R ladder DAC with an O-Core transformer, I²S input, and a natural, musical sound that easily competes with delta-sigma converters costing far more.
DACs RAW-MDA18.0
A $239 balanced DAC/headphone amp with dual ES9039Q2M chips that doesn't sound like every other ESS box - warmer tonality, forward mids, and a flexible soundstage.
Headphones Luan8.1
A semi-open dynamic with real wood cups and a natural, chocolatey midrange - $360 at launch, now $299.
Headphones Verum 18.0
A $349 open-back planar that goes the opposite direction from most of the market - smooth, refined highs, full warm mids, and ruler-flat bass to 20Hz.
Speakers Chors 58.5
A 2-way closed-box floor-stander with ceramic-coated drivers, fast dynamic bass with no port, and uniquely smooth treble - one of the most distinct speakers in its class.
Speakers DIAMOND B-60 v.38.2
Bookshelf speakers with no parallel surfaces, neutral and organic tonality, and a midrange focus that's so inoffensive you'll listen for hours without noticing time pass.
Accessories 4-all-in-1 Cable Set8.5
A pre-matched cable kit at €790 (or PRO version) - speaker cables, power cord, and shared geometry tuned together to give you synergy out of the box without trial and error.
Headphones Orchestra Lite8.0
An 8-balanced-armature IEM with a 3-way crossover at $249 - mid-forward, naturally warm, with depth-focused staging that's the opposite of most IEMs in its class.
Headphones RE2000 PRO Silver8.8
An older HIFIMAN flagship IEM with the same topology driver as the RE800 but a CNC-machined aluminum shell - by far the most detailed IEM I've ever heard at $349.
Speakers Borea BR098.0
Three-way French floor-standers with three bass drivers, neutral tonality, and a bigger-than-expected soundstage - balanced, distortion-free, and free of overdone bass.
Headphones RE800 Silver8.0
An older flagship IEM with topology driver tech, now $100 (down from $600) - audiophile-grade performance with surprisingly wide staging and an interesting non-target tuning.
Microphones & Recording PUC2 Mic LEA8.6
A €769 audio interface from Germany with proprietary LEA leveling technology - automatic perfect mic levels, zero-latency monitoring, and a slightly warm, transparent sound.
Accessories Brown Sugar BSSC95xx8.5
Melodika's flagship 9.5mm² LITZ speaker cable - super thick OFC copper, hand-finished Italian leather, and a big improvement in extension, dynamics, and treble air.
DACs PS2007.0
A $89 ESS-based DAC that measures fantastically but illustrates why specs aren't the whole story - it sounds fine, just not exceptional.
DACs DL1008.2
A $179 balanced DAC/amp combo with MQA, DSD256, 4 Cirrus Logic chips, and a clarity-focused house sound that punches well above its budget category.
Headphones Arya Organic9.2
A continuation of the Arya series at $1,300 (or $1,100 on sale) - the most resolving headphone at this price, with spectacular detail and bass you can feel.
Headphones Arya Stealth8.7
An exceptionally comfortable HIFIMAN flagship at $759 with a rare warm-leaning balance, unbeatable imaging, and a taste of high-end sound at a non-flagship price.
Headphones Robin SV0217.8
A $149 closed-back dynamic with real wood earcups, masterpiece-level build, and a fun, exciting V-shaped sound that breaks the 'budget closed-back' mold.
Headphones Ananda Nano8.6
A nanometer-thickness diaphragm trickled down into the Ananda line - one of the best picks in its price range, with detailed treble that can occasionally cross the line.
Headphones Ananda Stealth8.8
An overlooked HIFIMAN planar at $359 with a slightly warm tonality, fantastic imaging, and a 'pleasantly wet' sound that beats the Edition XS in almost every way.
Accessories Brown Sugar BSSC45008.2
A higher-tier 4.5mm² LITZ speaker cable that delivers tighter mid-bass, better instrument separation, and a more natural, lifelike sound - a clear upgrade over the BSSC3300.
DACs DO100 PRO8.0
A balanced lower-mid-range DAC with dual ESS chips, MQA, DSD512, and a tinker-friendly DPLL value control - solid sound that doesn't break records but offers great value.
Accessories P902E6R + USB Cables7.8
Sub-$150 high-end power cables and audiophile USB cables that brought tighter bass, a wider soundstage, and unexpectedly large clarity gains across an entire HiFi chain.
Headphones EM6L7.6
A budget hybrid IEM with 1 dynamic + 4 BA drivers, a 3-way crossover, and an attempt at the Harman 2019 target - mostly successful, with a fun 'weirdly big' soundstage.
Speaker Amps & Preamps AD-2PRO+8.8
A 36 kg, 240W integrated amp with switchable Class A and Class A/B modes, neutral tonality, and the kind of dynamic headroom that pairs well with virtually any speaker.
Accessories Brown Sugar BSSC33007.5
Polish-made spiral LITZ speaker cables - clean, neutral, and detail-rich, but the 3.3mm² gauge is on the lighter side for full dynamic punch.
Accessories AS-EU08 + SP-USB8.0
An affordable alternative to PS Audio and AudioQuest. The AS-EU08 paired with the SP-USB delivers a darker background, lower noise floor, and a more refined sound.
Headphone Amps EF4007.5
An entry-level Class AB amp/DAC with HIFIMAN's Himalaya R2R DAC, fun subjective sound, and a slightly soft character - underpowered for the hardest planar loads.
Accessories PS75R1R, CAT 8, P903M07.8
Affordable audiophile cables from AliExpress that genuinely deliver - silver RCA interconnects, OFC CAT 8 Ethernet, and a power cord with real, audible improvements.
Headphones E-PROTOTYPE8.0
Unlike anything you've heard or seen. The E-PROTOTYPE goes to extremes - both positive and negative - using proprietary technologies you won't find anywhere else.
DACs PS1007.0
Below $30 for a DAC. It's not a measurement monster and the sound doesn't shine in any aspect, but it does what it has to do - and frees up your budget for a better amp.
Headphones Svanar Wireless7.8
A $499 single dynamic driver TWS with an R2R DAC and LDAC. It's both lacking and feature-packed at the same time - and it actually delivers where it matters.
Headphones Sundara Closed-back6.8
Sundara, but cheaper, better isolation, easier to drive? Nope, not even close. An entirely different headphone that manages to be mediocre in every way that matters to me.
Headphones Sundara9.0
An amazing value proposition - the latest Sundara revision performs exceptionally well at $299 in the open-back planar market. It's just a steal.
Headphones HE400se7.6
A stupidly cheap open-back planar with Stealth Magnets technology at $109 - loved by some, criticized by others. So what's actually going on with it?
Headphones HE-R96.9
Both terrible and amazing at the same time - the HE-R9 is a closed-back bass monster at $199 with a tuning that's either perfect for you, or completely wrong.
Headphones Edition XS8.7
An exceptional open-back planar at $269 with a sound signature that's hard to find elsewhere - held back only by a controversial headband design choice.

What gets reviewed, how to use the catalogue, and how the verdict scale actually maps to gear you can buy.
Headphones (open-back, closed-back, planar magnetic, dynamic, and IEMs); Speakers (bookshelf and floorstanding, passive and active); DACs (desktop R-2R ladder and delta-sigma DACs, budget to reference); Headphone Amps (desktop headphone amps and R-2R DAC/amp combos, balanced and streaming); Speaker Amps & Preamps (power amps, integrated amps, and line preamps for loudspeakers); Digital Sources (digital-to-digital converters and transports for hi-fi playback); Microphones & Recording (condenser, tube, dynamic and USB microphones, plus audio interfaces); Accessories (cables, power conditioning, network gear, and room treatment). Each has its own hub under /reviews/, and every review sits in exactly one of them.
Open the category page that matches what you are buying (headphones, speakers, DACs, etc.), sort by score, and look for pieces tagged "Highly Recommended" or "Reference". Each review includes the price tier and direct comparisons against gear in the same bracket, so the best value is usually the highest-scoring piece at or below your budget.
Reference is the top of the verdict scale, for scores of 9.2 and up: a product that sets the standard in its class, and rare by design. It is not necessarily the most expensive option, and it does not mean the product suits everyone. It is also not the same thing as the test chain, the gear every review is compared on, which is chosen because it stays the same from review to review.
Roughly weekly during normal periods, sometimes longer when a flagship piece needs an extended listening window (four to eight weeks is typical for top-tier headphones, amps, and DACs). Subscribe to the RSS feed to get every new piece without checking the site manually.
Trust the reviewer who publishes their methodology, names the comparison gear, discloses every loaner unit, and writes negative verdicts when the gear deserves them. Every review on The Audio Stuff names the gear it was compared with and links the published testing method, which says plainly that the listening is sighted. Most flagship units are lent and go back, and there are no sponsored verdicts and no pre-publication review for brands.
Rarely, and only by the editor's hand. A published score is not recomputed when a price moves or a newer product arrives. When the editor changes one, the review keeps the earlier score under Score history, with the date and the reason.
Compare the verdicts. Scores compare within a category, each set against its own category's reference. Nothing tests whether an 8.5 headphone and an 8.5 DAC are equally good, so across categories only the verdict carries one meaning, and the verdict bands are this site's own.
