Never should’ve sold by vinyl collection. Vinyl recorded onto reel-to-reel or a high quality cassette deck sounds (to my ears) far superior to digital. Can listen for hours on end. Digital, otoh, get irksome after less than an hour of listening. Don’t know exactly why.
I still have my vinyl collection - about 200 albums in all - some date from 50's to around 1990. There is nothing like the sound of vinyl...and recording on reel to reel boosts the sounds so well that you can hear every single instrument in detail.
I agree that digital doesn't come close to high fidelity stereo or quad-sound that we used to get on vinyl or reel to reel.
