I've actuallly never heard the Maggies, but I hear from people who really like theirs. I admit to being curious. I am going to look them up now. I am starting to get concerned that my source (in my sig) is severly lacking. About Jazz recordings, it really depends on what era we are talking. Most of them are studio. That's a controlled setting. I have several live recordings dating back many decades. Jazz recordings are likely the 2nd best way to test speaker abilities. People say vocals are best because human ears can more easily discern when they are being "colored" but the saxes, muted trumpets, and piano are better for me. Why? Their wave forms are going to be CRAZY. That's what I want as the benchmark for the midrange and tweeters of speakers. I also like to listen to music direct, if it is an option on a source player or pre/receiver, but the LSi's (though powered with seperates) never gives enough to the low end, or the recording engineers weren't very good.
