My father worked for IBM and he and some of his buddies got together and bought Knight Stereo Systems kits back in the 60's and assembled them. So when I grew up, I listened to that back in the 70's. It was lo-fi but few cared or had better. At the time it was a good system.
When I was in college I read Stereophile and WhatHiFi magazines and bought their recommended components. I bought a Pioneer CD/DVD player, an Arcam Amp, Rotel pre-amp, Celestion 3 speakers. I had full size speakers to, but I'm too lazy to go look at the manufacturer. My old college stereo system is sitting here, I don't use it. The components are all from 1995 - 2000. The components are not bad just old and I do not buy CDs any more.

I get my 24 bit 192 kHz streamed music from Qobuz and Tidal. Tidal had a deal a couple of months ago where they give you a month or two for $2, then it's $10 per month, so I took it. The deal at Tidal may still be going.
The reasons why I like Qobuz and Tidal are that they have a wide variety of high bit-rate music. It isn't all 24 bit 192 kHz, but it is all CD 16-bit quality or better I believe. I look for 24 bit 192 kHz tracks to play. You can even download the tracks, but I have not done that yet.

So far on Tidal I like Joni Mitchell, Supertramp, Miles Davis, Stevie Ray Vaughan, Rush and The Carpenters.
Three months ago I bought a JDS Labs Element IV DAC and SYNAPSE USB that attaches to my home computer. It took me about 5 minutes to unbox and get it all plugged in. I try to listen to some 24 bit 192 kHz music every day. It's excellent! So excellent that I bought Focal Clear MG open back headphones. I never had open back headphones but the soundstage is supposed to be very good.
