Turntable and subwoofer in the same room? Here's how to stop the feedback loopA subwoofer and a turntable sharing a room can turn a great pressing into mud. Here's how to place both so bass and vinyl actually get along.
Class D amps have won the value war. Here's why I'm still not 100% soldClass D amps now deliver serious power for giant-killer money. Dave Okafor breaks down what you actually gain, and give up, versus solid-state and valve gear.
IEM ear tips: the free upgrade that beats most cable swapsEar tips shape IEM sound more than most upgrades costing real money. Here's how seal, bore size and tip material actually change what you hear.
Cartridge alignment: why the last half-millimetre matters more than the cartridgeOverhang, zenith angle and azimuth decide more about vinyl sound quality than the cartridge you buy. Here's the engineering, explained by a digital guy.
First reflections: finding them with a mirror before you buy any panelsBefore you spend a cent on acoustic panels, find your actual first reflection points with a mirror and a torch. Here's the method, and why it beats guessing.
Streamer output stage vs speaker sensitivity: matching the digital front end to your pairYour streamer's output impedance and gain structure interact with speaker sensitivity more than most buying guides admit. Here's how to actually match them.
Building a home cinema budget: the spending order that actually pays offWhere to put the first dollar in a home cinema build, and why most people spend it on the wrong box first. A spending order from twelve years of installs.
Six-figure DACs: what the money actually buys over a good $2,000 boxI've compared statement DACs costing more than a car against a good $2,000 unit. Here's where the extra money genuinely goes, and where it doesn't.
Subwoofer output limiting: the setting that quietly ruins cheap subsMost budget subs sound worse the harder you push them because of built-in limiter behaviour, not the driver. Here's how to find the real ceiling.
Watts on paper vs watts that matter: matching amp power to real speakersWhy the watts-per-channel number on the box tells you almost nothing useful, and how to actually match an amplifier to a speaker without overspending.
Turntable in the theatre room: why vinyl and Atmos rarely mix wellVinyl and a dedicated Atmos set-up can share a room, but rarely share a rack. Here's why, and what I'd actually do about it.
Turntable isolation: why footfall and feedback matter more than the plinthSuspended floors, speaker vibration and footfall do more damage to vinyl playback than plinth material. Here's how to actually isolate a turntable.
Budget subwoofer, right spot: why placement beats price every timeA cheap subwoofer in the right spot will beat an expensive one shoved in the wrong corner. Here's how to find that spot without buying anything.
Why your streamer's output stage still shapes the sound at the speakerBits are bits, but the analogue stage after the DAC chip in your streamer still colours what your speakers do. Here's what actually matters.
Diffusion vs absorption: the treatment decision statement rooms get wrongSix-figure speakers, dead-flat frequency response, and a room that still sounds wrong. The fix is usually a diffusion problem, not an absorption one.
Headphone impedance and power: why your amp's output matters more than wattsWatts on a spec sheet don't predict how a headphone amp will actually drive your cans. Here's the impedance and output-impedance story that does.
Why your multiroom volumes never match (and how to actually fix it)Same track, same app, different loudness in every room. Here's the actual engineering reason multiroom volume matching fails, and how to fix it properly.
MQA is dead. Here's what that actually means for your streaming serviceMQA's collapse left a lot of confused shelves of "Masters" tier subscriptions. Here's what actually changed, and what to do about it.
Standmounts near-field, floorstanders far: matching speaker format to listening distanceListening distance changes which speaker format actually works. Here's how near-field, mid-room and far-room seating should shape your standmount vs floorstander decision.
Desktop headphone setups: getting the desk itself right firstBefore you chase another DAC or amp, sort the desk. Reflections, cable strain and monitor height quietly wreck more desktop headphone rigs than gear ever does.
Speaker cable gauge and length: when it actually changes what you hearSpeaker cable gauge and length can measurably shift frequency response over long runs. Here's the maths, the thresholds that matter, and where to stop spending.
Subwoofer size versus number: why two small subs beat one big oneA 10-inch sub in two spots usually beats a 15-inch sub in one. Here's the room-mode maths behind why, and when a single big box still wins.
Toe-in angle: the free speaker upgrade nobody bothers measuringToe-in angle changes your speakers' tonal balance and imaging more than most upgrades. Here's how to actually find the right angle for your room.
Open-back headphones and a shared house: when the leak actually mattersOpen-back headphones leak sound both ways. Here's how much, when it genuinely matters in a share house or apartment, and when it's a non-issue.
DAC chip specs are marketing. Here's what actually decides sound qualityESS, AKM or a "flagship" chip name tells you almost nothing about how a DAC sounds. Here's what genuinely separates a good one from a dud, on any budget.
Bass management over network audio: why your streamer's DSP matters for subsModern streamers now carry crossover and room EQ duties that used to live in an AVR. Here's what that shift actually changes for your subwoofer.
Digital source, analogue speakers: why your streamer choice still shapes the pairA DAC engineer's take on why speaker matching starts upstream — how digital volume, output stage and streamer choice interact with standmounts and floorstanders.
Multiroom for headphone listeners: building a private zone that doesn't sound like an afterthoughtMost multiroom systems are designed around speakers in rooms. Here's how to build a headphone zone into that same ecosystem without gutting the sound.
Statement turntables: what six figures of vinyl front-end actually buysFrom air-bearing platters to outboard motor pods, what separates a reference turntable from a very good one, and why the gains get smaller as the price climbs.
Acoustic treatment at the statement level: what six figures of speaker buys you in a bad roomEven reference loudspeakers can't out-engineer a bad room. Here's what serious acoustic treatment actually buys a statement system, and where the money should go first.
Lip sync and audio delay: why your AVR's setting isn't the whole fixYour AVR's lip-sync slider only fixes part of the chain. Here's where audio delay actually comes from and how to measure it properly.
The last ten per cent: where statement systems actually spend their moneyPast a certain point, extra dollars buy engineering headroom and craft, not more sound. Here's how to tell the difference in a statement system.
Phono preamp gain and loading, explained by someone who'd rather not own a turntableGain and loading settings on a phono stage aren't optional extras. Here's what they actually do to your cartridge's signal, explained without the mysticism.
Speaker stands and boundary distance: the invisible spec on your spec sheetStand height, mass and distance from walls change a standmount's measured bass and imaging more than most upgrades. Here's how to get it right.
What a statement headphone system actually buys you over a good oneA look at what genuinely changes when you push a headphone system into cost-no-object territory, and what you're really paying for once the sound has stopped improving.
Where a vinyl system's money actually goes: spending in the right orderA former record shop owner on the real spending order for a turntable system, and where extra dollars stop buying you anything.
Subwoofer crawl vs measurement: how to actually find the right spotThe subwoofer crawl is a good starting point, not a finish line. Here's how I actually locate sub placement on real jobs, and when to trust the numbers instead.
Damping factor and output impedance: what actually happens at the speaker terminalDamping factor gets thrown around like a quality score. It isn't. Here's what the number actually measures and when it matters.
Headphone listening rooms: why the space around your head still mattersHeadphones bypass room acoustics for the direct sound, but the room you sit in still shapes fatigue, focus and what you hear. Here's why.
Where you put the DAC in the signal chain (and why it changes the sound)DAC before or after the preamp, streamer or separate box: where the conversion happens in your chain affects noise, volume control and cable runs more than the chip inside it.
Four-subwoofer bass: what a statement system actually buys youFour subwoofers aren't about loudness. Here's what a properly configured multi-sub array actually fixes that two subs, EQ or a bigger single box never will.
Loudspeaker sensitivity and amplifier matching: what the numbers actually predictA speaker's sensitivity spec and an amp's watts-per-channel number look simple but rarely tell you what you think. Here's how to actually match them.
Multiroom for headphone listeners: getting a private zone rightMultiroom systems are built around speakers in rooms. Here's how to get a proper headphone zone out of the same network, without losing resolution.
Bit-perfect and PCM vs DSD: which digital format claims actually matterDSD, MQA, bit-perfect, hi-res PCM — Nell Shaw sorts which digital audio format claims genuinely change what you hear and which are marketing noise.
Bass trap placement: why corners aren't always the answerCorner bass traps are the default advice, but they don't fix every room mode. Here's how to actually find where your bass problems live before you buy foam.
Clamping force and headband sag: the comfort variables nobody measuresFrequency response gets all the graphs, but clamping force and headband sag decide whether you'll actually wear a headphone past the twenty-minute mark.
Streaming to headphones: how your service and DAC settings actually shape the soundWhat actually changes when you stream to headphones: service quality settings, exclusive mode, and the DAC steps that matter more than the app you use.
Why room correction can't fix your DAC, and your DAC can't fix your roomSplitting out what a DAC upgrade genuinely changes from what only acoustic treatment and correction software can fix, so you spend on the right layer first.
Speaker format by room: when standmounts beat floorstanders (and vice versa)Choosing between standmounts and floorstanders isn't about budget or looks. It's a room-shape and listening-distance decision, and I've watched it wreck good systems.
Atmos speaker placement: why height channels fail in most roomsMost Atmos height channels underperform because of placement, not gear. Here's how to actually get overhead sound working in a real room.
Cable and interconnect upgrades: where the money stops making senseA measurement-led look at speaker cable and interconnect spending: what genuinely changes electrically, what doesn't, and where to stop.
Subwoofer placement by the numbers: the measurement approach that actually worksForget "sub crawl" folklore. Here's how to place a subwoofer using real in-room measurements, and why the corner is rarely the answer.
Crossover points and driver integration: what actually matters when you buy a speakerCrossover frequency and slope shape the sound more than most spec sheets admit. Here's what the numbers actually tell you about driver integration.
AVR vs processor plus power amps: when to make the jumpThinking about splitting your AV receiver into a processor and separate amps? Here's the engineering case for and against, without the marketing fog.
Clock sources and jitter in home cinema: what actually mattersJitter gets blamed for everything from harsh treble to flat soundstages. Here's what clock sources actually do in an AV receiver and where the worry is misplaced.
One subwoofer or two: why a second sub fixes what EQ never willA second subwoofer often solves bass problems that EQ can't touch. Here's why multiple subs smooth response across a room, not just at one seat.
Feedback and damping factor: what negative feedback actually does in an amplifierNegative feedback gets blamed for "solid-state sound" more than any other design choice. Here's what it actually does, measured, and why the folklore doesn't hold up.
Streaming resolution vs your ISP: why the bottleneck usually isn't your networkBlaming the NBN for dropouts and dumbed-down streams? I measured the actual bandwidth hi-res audio needs and it's rarely the wire that's the problem.
Why your DAC's output impedance matters more for headphones than its DAC chipThe chip inside your DAC gets all the marketing. The output stage that actually drives your headphones gets almost none. Here's what to check.
Sealed vs ported subs with a turntable in the room: what actually changesPorted subs and suspended timber floors don't always get along with a turntable. Here's how sealed vs ported bass actually behaves when vinyl is in the signal chain.
