Hang in there partner, unless your very rich it can take quite some time to build a large collection.Here’s my modest surround collection. I’m new to mutlichannel-my first 5.1 disc (Close to the Edge) arrived January 20th, and this is what I’ve acquired since then. I may have gone a little crazy in a short amount of time
Edit: Blue Train is not multi—sorry!
The good news is that today there's so much available on Apple you don't have to spend a fortune.
Good Luck.
