When to give up CDs and TT?

HI here is my opinion.

Easy answer, never. Its so nice to have all 3 options as each represents a different aproach/ lisining culture.

With LP's yuu have all the artwork and a sublim size of the cover,

Lisining to LP's are mostly one side at the time and the ritual of puttin it on the turntable makes you  biased for what to come, beside that they often feel more precious because they were hard to get. The music was made for recordplayer and often sound best there and its the way you are biased.

Lisining to CD hasent the same as the LP but still you have some kind of album but you somehow dont have the same respect for them, they dont feel so much like art but they still are something fysical and like the LP's is made a lot of fun finding them. They mean something.

Streaming music are much more consumerist, you have access to millions of tracks but dont have the same feeling for the tracks and you easily tend to quickly skip. Here a track dosent have any value for you and its easy to forget the music again when you hunt for something new. You easily spend a lot of time searching and its so far away from the experience of going into a good record store and feel the vibrations and passion for the music.

Streaming is a new way to acquire music and great for finding new music but it easily leads to a bad culture of "using of throw away" and you are now that emotionel connected. which easily means you dont dive so deep into the music and may miss a lot.

SO dont throw your old music culture out, once the streaming isent the exciting new gadget anymore you will miss the old LP's and CD'c.

When I got into streaming I did sell and give away many of my discs. Specifically the ones I rarely if ever listened to.

If you're like me, you have a core collection (in my case it's somewhere between 100-200 discs) that is played often, or at least a few times per year. And then a whole bunch more that you just have sitting on the shelf, but almost never actually play. I found that I couldn't bare to part with the former, while I really don't miss the latter. Streaming is very enjoyable and you don't have to completely get rid of all your media in the process. 

@curiousjim stated, "When I was young, I abused my vinyl with cheaper turntables and whatever cartridges they came with, and I wore out a lot of albums!"

The whole notion of using Vinyl is to create an end sound, which is only achievable through the use of the Vinyl LP.

Using the Vinyl LP is putting an interface into play that is sacrificial to two critical materials. The Groove Modulus and the Cartridge, especially the Stylus, are from the outset deteriorating.

The better the understanding of the absolute requirement for the Interface is, where the notion of longevity is being catered for. The less that is known, the speedier the deterioration will occur.

I myself have put Albums and Cartridges through the wringer, but would I change a thing? I was young and exuberant, without much influence of sentiment, whereas today, those very same Albums that went off with me on excursions are looked on, 40-ish years on, with a real fondness.

Talk to a Vinyl collector, and the notion of unpeeling the cellophane wrap on Album is classed as an abuse. The same album suggested to be played on a TT, is the equivalent of desecrating the sacredness within. 

I have one Album with this status, which is the original pressing of Pink Floyd 'Pulse', one replay will see the value fall by nearly £500. I'm sure there will be other descriptions for what has been abused if I play that one. Reserving it for the first £10K Cartridge ever used is a good deterrent to keep it pristine.     

That is something only you can answer for yourself.

I will never give up my Vinyl collection. I have been collecting since 1967 and have over 3000 LP's.

I have a much smaller CD collection in the 100's, but I'll keep those as well.

I only stream when I'm lazy or want a marathon listening session without interruption.
