i have the logitech x-540 5.1 system for my computer and i like it just fine, especially for the $40 i spent on it. i am not an audiophile so i dont need an expensive system. im looking for something for my living room now, and will have an htpc, hdtv receiver, and xbox. i am looking for something either roughly equivalent to my X-540 system but with multiple switchable inputs, or else an audio/video switcher that i can plug 3 different inputs into. i dont know much about this stuff so any help is appreciated. thanks!
