<font color='#000000'>Yeah, particularly the Alpha's are excellent for the price. I spent much of the day at Ultimate Electronics, and they had a nice setup w/ 4 matched bookshelf Infinity Alpha's w/the matching center & a smallish sub. I thought it sounded remarkably good (playing a DVD of Brian Setzer Live in Japan, great disc...). Much better than the Klipsch or Def Techs.
It does seem like the Infinity's are less hyped, tonally, and certainly would be my choice if one was going to listen to more than rock (eg Classical or a lot of acoustic music). The old clique is that JBLs are rock speakers, and at the lower price range this seems to be true.
Still, tastes vary. I like the Infinity's because they use driver technology similar to my Monitor Audio speakers, and they have a similar character (to my ears, they're very neutral, but I'm sure everyone is used to the sound of their own speakers. Although that neutrality and midrange sound is why I bought them). I like the JBLs a bit to the Klipsch- just a little too forward and spitty sounding for me. Maybe with the right gear, or tubes, they might sound a bit more mellow.</font>
