Hello, all- I'm looking to buy an iPod/MP3 player for mainly working out and plane trips, etc. However, I was wondering if these things were able to be hooked up to your receiver- I've heard the MP3 quality isn't as good as CDs- is that true? Is it noticeable if you can play it through your receiver and speakers?

If it's possible to hook them up to your receiver, what's usually needed?

Just curious.

Thanks.
Eric
