I hope someone out there has the knowledge needed for my question. I am wondering if I can hook up a new cd carousel or dvd/cd player to my Pioneer SX580 receiver. I was looking at home theater systems and shelf stereo systems and my head began to spin. Then I had the thought that maybe what I should do is purchase the component and hook it up to my Pioneer and purchase some new speakers. Can I do this? Is it a good or bad idea? I have always liked the sound quality of my tube receiver. If it will work, I'd also like opinions about some decent speakers, including wireless.

Thanks,
Faith
