I think I'm in over my head on this board but you all seem helpful and friendly. I've been trying to research a CD player and I'm overwhelmed.

Here's what I have now:
2 Energy XL-250 floor standing speakers
Yamaha RX-496 Stereo Receiver
Sony CDP-C211 5 disc CD player

I don't want surround sound or home theater. I'd like to stick with the Energy speakers.

I do really want more than 1 disc capacity. Honestly, I had a hard time parting with my vinyl but I finally did because I was too lazy to get up and flip the darn things. Let alone play more than one. Color me sad but honest.

So, can I improve on what I have? For <$500 per component. Can I just get a CD player? Do I need to get a new receiver to hear improvement? I prefer not to get a separate amp. Would I do just as well with a shelf system?

It's for my living room which is approximately 12x14 with 10 foot ceilings and open to a ~12X24 kitchn/dining room. Pretty much the entire first floor of my house is open.

Thanks for your opinions!
