New special turntables designed to best engage with HD vinyl will likely have laser pickups. New HD stamping will allow more tracks or perhaps reduce the size of the disc. Add a little reflective polycarbonate, and Hello 1982!

I can't imagine this going mainstream, even to the man-bun-wearing hipsters who tout vinyl today, as the rest of the audio system chain (pre-amp, amp and speakers) are unlikely to be of high enough quality to enable one to tell the difference. It'll be interesting to see what the true audiophile loonies (thems with $100K + investments in sound systems, including $20K+ turntables) will have to say about this.

A laser record player has been available from ELP for several years.

f8lee-- I doubt this is aimed at 'mainstream man-bun-wearing hipsters who tout vinyl today' as you quaintly put it. I also seriously doubt vinyl enthusiasts have any similarities with your mythical species. 'True audiophile loonies (thems[sic] with $100K+)' is another silly characterization, if you knew anything about vinyl, or the people who prefer it. So, less sneering might improve your opinions.

Wish this came round about 40 yrs ago! Sounds like a very clever idea. It won't literally 'drag your vinyl' into anywhere cos you'll have to buy the new vinyl, along with a cartridge/stylus of adequate performance. Will the RIAA standards still apply?

"more amplitude" I think what you are referring to here is called "dynamic range".

@JimFox - I suggest youo read a few issues of Stereophile magazine or the Absolute Sound - note the ads and reviews in there for $20K+ turntables and $100K+ speaker systems. And those are the folks who were lamenting digital sound back in the day.
So the question is, with the earbud/bluetooth/relatively cheap speaker systems used by the vast majority of audio enthusiasts, will any of them actually be able to tell the difference with this so-called "HD" sound? Unless it eliminates the hiss common in vinyl recordings, I seriously doubt it.

There have been two attempts to get better definition on vinyl in the past. 40 years ago with DBX Disc - and in the early eighties the CX Disc.

they really need to do something about record and stylus wear. if they can send a man to the GD moon, they can find a way to make phonograph records crackle-proof.

I thought the appeal of vinyl was its warm analogue sound. If this process starts with a digital signal then it kind of defeats the purpose doesn't it?
