JBL speakers
I have a pair of JBL S310II speakers from the old studio series.
I really love their sound. However, i find that they are a little bit "metallic"
I mean, metal made instruments like cymbals or trumpets sound really great and lively. When i hear a ride cymbal on these speakers i can close my eyes and feel like i'm sitting behind a drum kit!!!!
However, wood instruments sound a little bit metallic. For example, acoustic guitars sound like they have metal strings instead of nylon ones (i'm exaggerating a lot).
I think that sheep is absolutely right . "warm sounding speaker kinda guys" won't like them.
Oh, and they do sound great with movies
My experience with higher end speakers is really limited (null i must say) so i'm not a really good point of reference. However, I hope that my thoughts help you.
PS: sorry if my english is bad
