Just how many is enough. I have 2500 collected over the years and management has made it clear, enough is enough. In the UK we have small houses compared with you guys, just not enough storage.
I read a few years ago about a Chinese enthusiast who'd bought a collection of over 250,000 LPs. My question, why? Someone worked out it would take over 20 years of constant waking hours listening, to get through them.
