Superconducting speakers, are they on the way? Would you be first?


Lots of hoopla right now about LK-99, a potential super conductor out of South Korea that is causing labs around the world to attempt to replicate their findings.

It got me thinking, for certain superconductors are already in use (MRIs) and a room temperature, low pressure superconductor would turn engineering on it's end, but how many of us would rush to the store to hear speakers made of LK-99? 

Does the idea of a hyper-modern material in your stereo excite you?

Really should have asked this in a different category.  How many of you would dump your $2,000 power cables for a super conducting power cable?

Would you still replace it if the new cable was $50?

Won’t be selling my cables or speakers just yet.

Replication attempts

As of 4 August 2023, the experiment has not been successfully replicated, despite the initial experiments being completed in 2020. No replication attempts have yet been peer-reviewed. After the July 2023 publications release, independent groups reported that they had begun attempting to reproduce the synthesis, with initial results expected within weeks.[6] However while positive results can come quickly, negative results are slow, as "falsification needs to verify all possibilities, and it will take a lot of time."[46]

The first attempts that published results did not observe levitation or diamagnetism, and their samples had high resistivity. None have published tests of flux pinning or specific heat capacity.

Early replication efforts gained global visibility, with the aid of online replication trackers that cataloged new announcements and status updates.[36] Some researchers released brief teaser images or videos before publishing any results, which received great public attention. On 1 August 2023, a team at Huazhong University of Science and Technology in China reported producing tiny flakes that showed diamagnetic levitation, on their second attempt.[13] On 2 August 2023, a team around Sun Yue at Southeast University, claimed to have measured zero resistance in a flake of LK-99 up to a temperature of 110 K (−163 °C; −262 °F).[47] Doubts were expressed by experts in the field (from the University of Maryland) that their results had what looked like a large measurement artifact, did not show the expected dropoff to zero resistance, and were quite noisy and unable to measure resistance below 10 µΩ, which is high for measurements of superconductors.[48]

Generation one of any new tech is not likely to exceed in overall performance of, for instance the speakers I have which have fifty years of refinement in them from the same company.

 

Any one else here try Windows 1.0… omg. I couldn’t get it to function on the new hardware I had.

 

Class D amps are starting to get closer to other pre existing amp types… in how many decades?

 

No thank you.

Room temperature superconductors and cold fusion seem to pop into the news every few years.  Both technologies are desperately needed to complete my newly designed warp drives.

They do indeed! :D I’m really just kind of thinking of how attracted audiophiles are to the concept of modernity. Having cutting edge tech.

 

 

Not without an amplifier that is .0000000002 ohm stable

@avanti1960 No worries, just need to start using current amps instead of voltage amps. :)

Does the idea of a hyper-modern material in your stereo excite you?

Not really; in the realm of speakers certainly not compared to the importance of physics, implementation and design. We’re exposed already, and have been for decades to the "wonders" of material evolution (rather than, as often advertised: revolution), but fundamentally it doesn’t change the limitations of a physically restricted/compromised package - which has been the less flattering hallmark of most home speakers since the 50’s and 60’s. Computers, another matter.

No thank you.

Maybe tube amps were simply the better outset musically speaking compared to Class D topology, not least in the form of SET’s over high efficiency, high impedance speakers which were their natural mating partners anyhow. I’m sure the notion of equating the technological achievement with the transistor and the acoustic suspension design with something that was in the interest of actual sonic advancement could be be tempted..

The only thing that will excite me is already designed :

Dr. Choueri BACCH filter...

Gear design matter , be it cables and new amplification concept or new materials ...

But gear design matter less than acoustic  improvement and psycho-acoustic discoveries...

Give me any good speaker it will sound great in the room i will make for them...
