Been buying CDs since 1993 and I’m not going to stop. Charity shops and eBay are regular haunts.
The current vinyl bubble is a double-edged sword. On the one hand, too many bands/labels only put out music on vinyl now and the humble little CD has been shunned because let’s face it, if you can charge a physical-buying schmo £30-40 for a 12" why bother with £10 CDs? On the other hand, vinyl nerds have been (inexplicably) getting rid of their CD collections as they upsize and I have been reaping the rewards and finishing out my collections as they sell their unwanted drinks coasters for (mostly) peanuts.
There’s stuff I’d like on vinyl for the sheer collector side of it, plus obviously lovely big art, but I always feel they’re a trade-off in terms of occasion/ritual over sound quality. My grandad was a sound engineer who built his own speakers and amplifiers and I remember him basically saying that CDs were the pinnacle of sound reproduction and it’s stuck with me.
