I get where you are coming from as well.
I currently have about 600 CDs with a growth rate of about 6 - 10 a month at the moment.
Due to the fact that I work away from home a lot I don't get as much time to listen to music on a stereo setup I have spent £000s on

. I only get to listen to music about 7 - 8 hours a week.
I do own an iPod but only use it on planes. I am sat in a hotel room at the moment but I am not listening to my iPod because it's just not the same as listening on a good stereo setup at home. I listen in my car - but that's not the same either.
When I win the lottery I will build a dedicated listening room with stupid amounts of money spent on amps & speakers and have my whole house loaded with speakers networked into every room.
Until that time I have to make do with the time I can set aside for music .
Funnily enough I am the opposite of Pezzerino. If I don't get to listen to some good music properly on a regular basis I get withdrawal syptoms

.
Do I enjoy it any less or will I stop buying more music ?
NO CHANCE
