From what I've read the A5's have the best sound quality, then Soundsticks, and then the Sony.

Harman Kardon Soundsticks III: http://www.amazon.com/gp/product/B0042F3K9W/ref=gno_cart_title_1
If you can name any others it would be great!
Note: They will be used with an iPod. Except the Sony one, cause it has CD Player and radio.
*iPod Classic > LOD > PA2V2 > Speakers
Genres: Rock, Alternative, Metal, Grunge, Punk, etc.
Based on the genres I listen to, I don't need a subwoofer, but it would be good to have one as a feature.
