That is my experience as well with the Preludes: non fatiquing and very musical. Although I have not heard a great deal of "audiophile grade" speakers I can say I like these better then my quad 21L's and GR Research AV-1's which are no slouches. Although this is a very balanced speaker from top to bottom I feel the midrange really stands out and they match up great with my Tad 1000's and Tad 150 preamp. I was lucky enough to find a pair used in my area a couple of months ago, and although they are approx 10 years old and the fit and finish could be a little better (Reanaissance has vastly improved them in this area)I'm more then happy with these and think I would have to spend signifigantly more $ to approach the quaility of sound I'm getting from the Preludes. I do wonder what kind of improvemements have been made to these, if any over the last several years or so and may contact Renaissance to find out
