I have had the gma callisto's for almost a year. I second everything that bombaywalla has written. in addition, the bottom end is very well defined and clean. obviously you don't get the big dynamic oomph, but - and this is important to note - you get the bass that is in the recording, and it is incredibly well integrated with the mids and highs. if you do a high proportion of your listening to jazz, folk, vocals of any sort, then you will be astonished. to do justice to rock, you need a different speaker, or add a sub. this is not to say that it is subpar, merely, that it's limitations become apparent with rock. i feel no need to upgrade.......at this point. finally, the people at gma are a pleasure to deal with.
oh yeah--- i have no other connection with gma other than being a happy owner
