About How Much $ Have You Spent On Your System & Is Your Room Acoustically Treated?

Also is your rig set up to get the most out of it or compromised by poor set up(ie:bad location hard surfaces etc..)?

5k, mostly purchased used.  Bought a brand new integrated amp last year.  I love the way the room sounds as is.  I just need more time/opportunities to enjoy the system and the room.  Very, very happy with it all and I occasionally hunt for new LPs/CDs.
About 35k retail. My basement space is well treated with a combination of ASC and Echobuster products, most of which I had left over from a previous room.
