SPL Audio’s Crossover is for users whose subwoofer either includes no low-pass filter because it’s passive; or who wish to bypass what’s built in for something superior. It’s also for those who prefer…

Unicorn sightings? That’s only if you misspell it. KEF’s new Uni-Core array is a patented solution to…

I wanted to send some sort of New Year’s wishes to my friends and colleagues but it is difficult in today’s world to know exactly what to say without offending someone. So I met with my lawyer yesterday and on advice I wish to say the following:

Here I was just thinking this morning that maybe it’d be a good idea to let Srajan know of new developments at Rethm and here I get an email from you with some pretty impressive detective work. Not sure who posted those pix and how you got wind of them…

Oh my Kron. No, today your rare direct-heated triode didn’t die a fiery death. Today we’re profiling Omicron’s Tesla…

A Xmas story: Unholy oil. Today isn’t about Exxon Valdez, Deepwater Horizon or corporate malfeasance though it does involve oil. When we relocated from Switzerland to the Republic of Ireland, our first home ran a geothermal pump for radiant floor heating. Keeping warm during the cold months was built in. Our second rental now…

KIH #81: SUBversion. Recent experiments with an active filter built into my new autoformer passive preamp have suggested a new wrinkle for skinning the multi-way condundrum (well, new to me at least). Pál Nagy’s icOn 4Pro Model 3 SE includes 4th-order Linkwitz/Riley 40Hz outputs. Those feed mirror imaged data to monitors and subwoofer. The former’s roll-off starts at 100Hz. It’s down -6dB at 40Hz, -24dB at 20Hz. The sub does the opposite. Perfect handshake. Before I get at the subversive goodies…

May I borrow your ork? If we did Lord of the Rings, that’d get us at bork. Hello loaner ork. Grunt. Alas, wrong movie. borg.audio who insist on the spelling invoke Starship Enterprise and its crew’s cybernetic phantom nemesis, the hive-mind Borg. Fittingly, two of their models…

Fake hifi news. There I was minding my very own bananas. Then this press release dropped. Clunk! Ouch! Doctor! …

KIH #80. The life of Pi in 2 and 4. Those numbers refer to half and full space. In audio they describe sound which either propagates omni as bass does—you get four pies for that—or sound which bundles like high frequencies over a 1-inch dome tweeter. That’s worth only two pies. Those who believe in fuller plates often reach for super tweeters. It seems a mistake to think them ‘super’ for additional bandwidth when human hearing doesn’t extent past ordinary tweeters. If a super tweeter can really hit 100’000kHz, it’s not germane to our ear/brain per se except perhaps for zero phase shift. There’s also the issue of first break-up modes. An aluminium tweeter which breaks up at 23’000Hz will reflect ugliness into the audible bandwidth unlike a diamond tweeter that’s good to 70’000Hz. But let’s return to our pie as a function of dispersion. If the ‘super’ in an add-on tweeter isn’t about bandwidth but broader dispersion, it should …

How will we be remembered? Marja & Henk were my oldest contributors. They joined 6moons when Ivette and I still called Taos/NM our home and listened to Avantgarde Duo speakers like our Dutchies did. They also were the only wife/husband reviewers I knew and knew of. Sunday before last, Marja emailed me a long very carefully crafted and detailed letter…

Shovelling shit? – When I launched 6moons in June 2002, I built my site in Adobe GoLive as the software I’d learnt at Soliloquy Loudspeaker Company. It was a default move. Use what you know. Adobe’s successor was DreamWeaver which still wrote static HTML. As such there were no interactive comments. Anyone wanting to comment or critique had to email me personally. My answer would then publish with the question unless the reader requested total anonymity. When I transitioned…

Not HorrorFi but a riff on the imagined overlap between horology and hifi. Today’s tickled into being with Jeff Fritz’s editorial on luxury hifi wherein he referenced Patek Phillppe; and hifi journalist Ken Kessler’s piece on Christopher Ward’s new super compressor watch.

Hattor not Hathor. Arek Kallas not Maria Callas…

There’s a new popemobile in town…

Upwardly mobile. What should I do next? It’s how some audiophiles work. They play their hobby not just on the music level which, if you stream content, is cheap these days. They also are constantly busy on the gear level which hardly ever comes cheap. Whilst some hardware buys might eventually turn out to be detours or explorations of alternate but not preferred flavours, the motivation behind it all tends to be simple: to ascend to the next level by significantly improving one’s sound.

People don’t just buy what they need. They buy what they want. That needn’t be the same. Case in point? Active preamps.

KIH #77 – Chinese chimera. A while back one of my writers was solicited to review new Chinese DAC Pegasus from new brand Musician Audio. As is policy, he checked with me first. Looking at their web link, I couldn’t help but see Denafrips…

KIH #76 – How to add some passive radiance to your sound…

With the cancelled Munich HighEnd 2020 show, here’s what Métronome’s Jean Marie Clauzel and Artesanía’s & Kroma’s Cayetano Castellano planned on showing in art-meets-sound style.

Mårten Design. Like their Danish colleagues at Børresen Acoustics, our Swedish team sport in their name a letter which for Brits and Americans isn’t on the keyboard. Like the Danes, it’s become a stylized part of their logo. Another mark of distinction goes to a long-standing collaboration with German driver supplier Thiele & Partners aka Accuton. Like Tidal in Germany and Albedo in Italy, Mårten champion their ceramic and diamond transducers over all others. So it’s no surprise that in their newly introduced middle range replacing the prior Heritage models, the three-deep Parker series goes all ceramic again, even offers an upgrade path to a diamond tweeter…

10 secrets to the best sex ever. 5 secrets to a toned body in just 30 days. 3 secrets to the perfect omelet. If there’s a subject, there’s a self-help book or weekend workshop. So here are my little secrets about how to assemble a personally fulfilling hifi system…

Pop went the weasel. There goes our weasel word musicality. Kapoof. Good riddance. That’ll be John Darko. He hates it. Rightfully so. “How was your food?” “Delicious!” “How was your weekend?” “Just fine.” “What did you think of those speakers?” “Awesome, dude.” Throwaway answers of no real meaning are legion. Using them to convey subjective listening impressions with any degree of specificity is impossible. How to express meaning with meaningless words? Calling a hifi “very musical” is like calling your car “very automotive”. A hifi plays back music. Of course it’s musical and not agricultural, medicinal or antiseptic…

We all know how strategically placed wall mirrors can make a room feel bigger and better distribute available light. German company Arakas—their name is an anagram for Acoustic Room Sound System—apply the same principle to sound by offering acoustic mirrors using an undisclosed surface material that’s stretched under tension over round and square frames…
