Fascinating, as are all of Techmoan's videos! Funny that, as CX was partly dreamed up to hold back the march of the CD, today CD is effectively a dying medium and vinyl is still going strong :lol:

Yeah, CDs were pushed onto the public by the bean counters.

Also, from what I remember, most (if not all) of the encoding systems for reducing vinyl noise) exhibited what what was called a "pumping sound" (to one extent or another) as the system struggled to decode and eliminate the unwanted sound. It was always a bit of a trade off that the purists rejected.

Perhaps, if it were to be introduced today, with modern digital technology, it would be more successful.

Yes. Techmoan already did a video about them way before his one about CX records.

CD is dead, but with vinyl I don`t think they will invent something like dbx, cx or quadraphonic again. This was all marketing steps to buy new turntables and records,but weren`t economically successful. CD was economically a huge success, but now the party is over. Compact disc opened the doors of digital music playback, so the invention became the victim of own revolution. And old relict vinyl record came back.

No, and I think playback from modern cartridges and turntables is so good these days it's not needed. More people have RCMs now so surface noise is less of a problem. With my current set-up dynamic range is already impressive without any enccoding systems, as is the lack of surface noise. We've come a long way.

Quadraphonic listening for music has never really caught on, in the same way that 3D films and video haven't, though they keep trying to reinvent it every few decades!

On certain fronts we seem to feel quite secure in the future of the vinyl format. But when you factor in the shrinking number of good gear repair sites, the fact that most retail stores are more interested in selling clothes, bedclothes, and curtains instead of vinyl related products, the fact that former music centered stores are now more interested in selling t-shirts, cheap DVDs and drone kits, and the fact that most new cars are only equipped to play virtual music which comes from subscription services or downloads stored on thumb drives, I see a much less rosy future for any physical music playback system. I never see anyone carrying records or CDs to the cash registers in stores that still carry those selections. They've even stopped carrying Crosley products. CD collections left in stores are pitifully bereft of variety, and you have to look carefully to find a new receiver with a built in phono preamp, much less a tape monitor loop.

That is because of webshopping. Majority of people buy vinyl on internet, it is more easy to get what you want. I also bought all hifi components on the web, because I got what I want and it was cheaper like in local store.

That is not reality. Actually all of new japanese amplifiers have built-in phono stage also on entry level. A few years ago reality was different, that is why there are a lot of cheap phono preamps still on the market. I see also otputs for tape recording on majority of them.

You have been saying "CD is Dead" for a while.Yet I can find almost anything on CD on Amazon and E bay to this day.It is not dead.I think you want it to be dead though because you blame CD's for the near death of vinyl back in the day.It is easier to get something on CD and for much cheaper than vinyl these days.

Actually, not. The format was pushed by Norio Ohga, so he could have uninterrupted classical recordings. And the maximum recording recording time was keyed to a symphony he liked, 82 minutes or so. The bean counters arrived later.

IIRC the CD was made with long enough play time to hold a specific recording of Beethoven's 9th.

Am I the only one who remembers how much a single CD cost back then? IIRC the cost was >$25. The Sony CDP-101 IME sounded awful. It had high frequencies that made me want to cut off my ears and run away.

COMPLETELY AND UTTERLY OFF TOPIC: The first CD players used one DtoA converter and switched it back and forth between channels. This resulted in phase errors that could do just what you heard. Or something else. That's the problem with phase errors: unpredictability:
Plus the first of anything isn't perfect. Remember the first transistor amps?
