How BIG is yours?

That is, music collection. Seems like everyone is proud of their big (physically, cost-wise etc) stereo systems. I want to know how big your music collection is. I always ask when I conduct a transaction, half out of curiosity, half wondering whether to trust the sonic biases of someone who owns maybe fifty-sixty albums/CDs tops. I'll start: I have around 500 LPs and 1500 CDs, more and more of which are the excellent DCC Gold and XRCD variety. Would you rather spend $100 on trying music you haven't heard or trying a new power cord (no wrong answer here, I do both)?
