Buy them and see if you like them better. Best Buy carries them so returning them would be easy if you don't like them. Personally, from what I have heard, the new E-series sound much better than the S-series. Granted, I heard them at Best Buy in a poor listening environment. I think JBL took a big positive step with their new E-series.
Not sure if the E30 sounds better than the S26. It may or may not. But in general, the E-series speakers seem to be a big improvement over the Studio and Northridge (sp?) series. I listened to the E80 and E90, I think, a couple of months ago. Not bad. Definitely better than the previous models. I actually liked them better than the Athenas which are a pretty highly regarded speaker in it's class.
It doesn't matter what any of us think. Go listen to them for yourself. It is JBL's opinion that the studios sound better than the E series, and if I'm not mistaken, the studio also costs more. Are you looking for new speakers or trying to find out every little detail about the JBL speaker company?
But do you guys still think the E Series are alot better??
I do, but that's just my opinion and my ears. You or someone else may find the opposite to be true. It all depends on what you like. Go listen and choose the speaker that sounds good to you. Like I mentioned earlier, buy them and try them out. If you don't like them, return them.
