I think you're massively underestimating how much gold costs. If my math is right, 1M of a single conductor 16AWG gold wire would have ~$1541 worth of gold at today's spot price. You'd have to sell it for obscene amounts just to get your money back and you'd probably have to have them pay upfront.

Given the volumes involved and the difficulty of actually obtaining that much gold and turning it into something usable, you'd probably have to charge at least $10k/m just to break even on a two conductor cable.

I think pure silver would be too fragile to make one of those speaker cables made of 78 individually shielded strands woven in a tennis net formation that costs $1000 a metre. Solid silver core 12 AWG, now we're talking.

If your speaker wires aren't solid 24 carat gold and thick as an industrial power cable then you're not really listening to music.

Wait this needs to be palladium. I think that's mildly toxic and also very expensive.

Pure silver interconnects were certainly a thing for connecting your iPod to your portable amp back in the day

IIRC they were paying >$100 for a cable a few inches long

There are definitely silver cables out there but I've never heard of gold, even at the stupid 80 grand MIT Cables level. I'd guess no supplier makes stranded gold wire for them to use.

The only thing white people deserve is a bullet to their empty skull
Pure gold is probably a lousy material to make wires out of. Not because of its electrical properties, but because terminating the connections would be difficult. It's so ductile that I doubt crimping would work well, and soldering to solid gold is problematic. (see: https://www.indium.com/blog/soldering-to-gold.php)

This gives me an idea for a listening room on a giant seismologically isolated platform. You know, so the sound of plate tectonics doesn't get in the way of your enjoyment of *reads notes* The Sheffield Track & Drum Record.

Why not the whole distance and hit a triple-isolated floating fully anechoic room? Of course, an acoustically dead room is a bit strange to be in, so the next step is to add a fully three-dimensional wave field synthesis system so that you can accurately recreate any room reverberation time curve of any venue or space you can think of.

It should be possible for somewhere between $500k and $1m, before adding your hifi of choice.

Context: This dude was adamant that his speakers have superior clarity and lower distortion than studio monitors costing 100x as much, based on a theory that Chinese manufacturers don't know that low frequency distortion is less audible, so they build their speakers and amps with super low distortion. And that somehow makes them sound better than studio monitors.

If it’s just for one day, find a local PA rental house and take whatever self-powered box they have. Something like a Yamaha DSR112 will be plenty loud and good, albeit not bluetooth. We’ve owned 16 of them for years and they’re one of our most versatile boxes.

ONLINE LECTURE
Perspectives On Audio: Information vs Data; Fidelity vs Resolution

Tuesday 17th August 2021, 7:00–8:30pm (approx.)
Bob Stuart, MQA

Audio bridges science and engineering with the complexity of the human listener. If we are to close that gap, we need to ask the right questions. This talk begins with a tutorial overview of modern auditory science that is pertinent to fidelity and resolution. It also sketches information flow in the listener giving some surprising estimates. Next, a quick tour through sound reproduction, starting with analogue, shows how a ‘narrow’ approach to digital audio has inadvertently embedded key errors in recordings and playback systems. This is briefly illustrated with seven theories of ‘High-Resolution’ and a consideration of the paradoxes of losslessness and data vs information flow.

When we consider the whole chain from microphone to loudspeaker, and more precisely define objectives for transparency using principles of communication theory, modern sampling theory and current auditory science, we show that a better engineering solution is indeed possible.

J. Robert (Bob) Stuart studied electronic engineering and acoustics at the University of Birmingham and took an M.Sc. in operations research at Imperial College, London. While at Birmingham he studied psychoacoustics under Professor Jack Allison, which began a lifelong fascination with the subject. In 1977 Bob co-founded Meridian Audio and served as CTO until early 2015. In 2014 he founded MQA Ltd where he is currently full-time as Chairman and CTO. At the request of Hiro Negishi and Raymond Cooke, Bob chaired the advocacy group Acoustic Renaissance for Audio between 1994 and 2002. In the 1990s he worked with Michael Gerzon and Peter Craven on lossless compression and was instrumental in its adoption for optical discs.

Bob has contributed to the DVD-Audio and Blu-ray standards and has served on the technical committees of the National Sound Archive, JAS and the ADA (Japan). In 2020 the Royal Academy of Engineering awarded him the Prince Philip Medal for his exceptional contribution to audio engineering. Bob’s professional interests are the furthering of analogue and digital audio and developing understanding of human auditory perception mechanisms relevant to live and recorded music. His specialities include the auditory sciences and the design of analogue and digital electronics, loudspeakers, audio coding and signal processing.

Bob joined AES in 1971, has been a Fellow since 1992, and is a member of ASA, IEEE and the Hearing Group at Cambridge. Bob has a deep interest in music and spends a good deal of time listening to live and recorded material.

This online lecture is organised jointly by the AES UK Section Cambridge Group and IET Cambridge Local Network. It is open to all, but registration will be required here. A link to the Zoom session will be sent to registered participants prior to the talk.

I want to build and sell an audio cable that's simply a heavily insulated tube filled with conductive liquid metal (highly prone to leaking if pierced). Ideally something dangerous like mercury.

Slap on some really nice cable sleeving, call it "stellar-grade audio" or something, suitable for use in space missions to the moons of neptune. The liquid metal really smoothes the highs and evens out the mids.

Price? Only available for hard gold bullion. Delivered, no certificates accepted.

Call me a heretic, but wouldn't the "liquid" be affected by gravity, atmospheric pressure and temperature?

Or is the word liquid simply the product name (they also have a liquid pre-amp)?

I'm pretty certain it's just in there filling the gap. If it was relatively well done without any cavities it would be conductive, and gallium anyway which is what I assume makes up the majority of what they use is fairly stable. It's just loving insane and funny and stupid though, also love that they come in pelican cases because it's illegal to ship gallium on a plane as it will decimate aluminum if spilled.

Also it made the MQA icon light up (briefly) despite Apple using their own lossless codec. I was waiting for audiophiles to say the lossless streaming they don't have to pay extra for isn't actually true lossless because gotta justify to yourself that $30 Qobuz subscription.

It is legitimately wild how someone who ostensibly is critical enough to require absolutely lossless audio is also satisfied with "LED go bright mean good." Especially when that LED is linked to a marker from a dead, proprietary format that had like 100 titles released. (I know it's more but whatever).

This is spot-on. I keep equipment for playing obsolete formats because I do a lot of work transferring old recordings; my clients need me to have a working DAT deck, a working Minidisc deck, a working R2R, etc. But on my own time you couldn't pay me to use any of those. I've never quite figured out why people cling to them, but I think it's a combination of "you casual listeners wouldn't understand" snobbery and the belief that because a technology wasn't picked up by the mainstream it must mean that it's superior in some way. FFS, there are dudes who are into the Elcaset and are seriously recording music onto and listening to that format.

I'd use the Minidisc because it's cool. I enjoyed the This Does Not Compute video about it bringing up that audiophiles hated the Minidisc because it wasn't high res enough.
