I am trying to decide whether to get the JBL s38's or the JBL s310's for my fronts. I have the JBL S-center right now.
If you have the S38's are you satidifed with the power and sound? Thanks.

Yep, I've got them. Unfortunately, I cannot tell you how it sounds cranked up (I live in a townhouse and when I even come close to what I would consider loud, the neighbors are none too happy).
I have them hooked up to a Harman Kardon AVR-35 receiver which comes no where near pushing them to their limits (I think it is rated at somewhere around 50watts per channel).
But I am very happy with them and they were exactly what I was looking for...
