Glad you asked about "Pace", "Rhythm" and "Timing"!! The fella that first mentioned these dynamics(viv-a-vis critical listening), Martin Colloms, is a highly regarded British audio reviewer, speaker designer and holds a number of engineering degrees. I thought some might care to read(carefully- all of it) the following treatise, and gain some illumination on the meanings the terms: (http://www.stereophile.com/reference/23/index.html) I just re-read it myself(I've still got the Nov. '92 Stereophile issue), and it's interesting how it flows so well with what was stated earlier about, "tight bass". Some of Mr Colloms works: (http://www.worldcat.org/search?q=au%3AMartin+Colloms&fq=ap%3A%22colloms%2C+martin%22+%3E+ln%3Aeng&qt=facet_ln%3A) (http://www.wiley.com/WileyCDA/WileyTitle/productCd-0470094303.html) I believe he may know a little something on the subject of audio/music reproduction! Happy listening!!
