Home Theater Cable Connection Questions

[Bluray Freak 2009]

Note:Best buy says they will supply basic speaker cables to connect the speakers to the receiver,but I want to know if there are better quality cables other than the ones best buy supplies, I already know a few types of cables I will need to buy they are in the list below.

I have read a little about the cables I need but not a lot so if I don't respond to this thread for a few days I'm just reading up on information about the cables I need. I know to use HDMI cables where ever possible.

Cables That need to be bought

Video Cables

1.HDMI Cables (2)
One that goes from the Receiver to the TV
One that goes from the Sony Playstation 3 To the receiver

2.Component Cables (3)
Nintendo Gamecube Component Cable *
Nintendo Wii Component Cable
Sony Playstation Portable Component Cable

I know you might be thinking why hook up the Nintendo Gamecube when I have a Nintendo Wii,I have two hardware items that don't work with the Nintendo Wii,The two items are the Gameboy Player and the Broadband adapter.

Video Cable Questions

1.I have a Sega Dreamcast that still works and that I still use,I have been using the red,white,yellow audio and video cables that came with it what is the best type of Video Cable to use when hooking it up to the receiver?

I apologize in advance if I am not allowed to ask this question but where can I buy first party Nintendo Gamecube Component Cables around this price range 20$-34$, you can PM me the link if you want.

Thanks In Advance For your Replys
