Raj and Michael, you have expressed precisely my own viewpoints. I am very gratified to hear that others understand this concept: that the driving force behind equipment upgrades for some of us is due to the discoveries we have found in the music, and that these discoveries have propelled us to explore a wider range of music styles. Even our collection of older recordings that did not involve us in the past suddenly become revelations when we listen to them anew after an upgrade.
I've kind of made it a mission to encourage fellow audiophiles to be drop some biases, be more adventurous, and try listening to some new stuff. Maybe not everything will appeal to you, but I've surprised myself at what I have found to be rewarding. I've come to discover and really enjoy various forms of ethnic folk, bluegrass, 50's and 60's Country, Medieval, Mel Torme, Elvis Costello, Natalie Merchant...music all over the board. This is in addition to my usual staples of straight ahead jazz, classical, and movie soundtracks. I guess one common thread is acoustic instruments recorded in natural space (not a recording booth). Although I do enjoy some techno, Blue Man Group, and 60's and 70's rock. I've got to look into acquiring more international artists. There must be some great music out there that I don't even know exists. DVV proved that by sending out a sample of Hevia with the Dezorel. I'm surprised no on else has commented on that cd.
