I'll provide full details here, but if you need any more information please ask. Thanks in advance for taking the time to help a rookie like myself out.
I have a 10x10 room with a 42" LCD tv. This is connected to a laptop via standard 1/8" cable; on it I have a large collection of DVD-ripped Divx files and V0 VBR MP3s. This is how I play all of my media; I don't watch "television" or need speakers for a cable box.
I have a $100 (retail 2007 price) pair of 2.1 Logitech speakers, currently. They sound good, or so I think.
However, I'm not content just accepting this. I'd love to improve my speakers. I don't think I need 5.1 or 7.1, so two speakers and a sub is probably just fine.
Here are some questions, if you can edify me
Can I get better sound quality with a "better" set of speakers?
Do I need a receiver? Would this help?
I'll never be playing Blu-Ray or wav files; would I be able to tell the difference playing V0 MP3s/Divx?
Would I be able to tell the difference in a tiny 10x10 carpeted room?
What kind of differences could I (potentially) notice, and for how much?
Any help is much appreciated. Thank you!
