Agreed: DON'T go for B(l)ose. You'll just be sorry. If you get ahold of a multichannel reciever (that is, if you want multichannel sound), you might want to look into
Axiom surrounds and such. Also, yes, that should handle any music. Assuming that you're using high-quality speakers, sub, electronics, and cables, you should be fine. As long as you don't overdrive your stuff, it'll sound great. And of course, high-quality cables means something like
Blue Jeans,
River Cable,
Impact Acoustics,
Ram Electronics, or
Cobalt Cable. And honestly, if you're looking to get a high-quality product on a budget but without the *BLING*, go for Blue Jeans or Impact Acoustics. Just make sure that if you go with Impact Acoustics that you opt for their best Interconnects. They have triple shielding, good measurements, and are still cheap!
