That's great! And don't feel rushed to upgrade everything. I'm going on 7 years and it's been a slow process. But one that you have to force yourself to stop and listen to music.
When I started out I always got excited looking at upgrades. Now I don't like upgrading because I have to audition and break stuff in. I'd rather have it all set up and just listen.
You will learn a lot on audiogon - just checking out the discussions.
Good Luck,
Rob
